Hi, im currently experiencing mini periodic lagspikes. When I try to ask google, it always refers me to Lol or some other online game.

 

What I experience are mini lag spikes that happen while the PC is running. I could check this by holding a key in a textbox allowing the character to spam itself. You would notice sometimes stops for a millisecond or so then goes on again. I could also check this by moving the scroll bar up and down and instead of moving fluidly, it moves erratically. 

 

When I check the task manager for the CPU usage and memory usage, they don't seem to be at full capacity. I find it weird why the pc lags behind. I would notice this in games where suddenly things slow down for a moment then speed up or whenever I code using IDE's.

I cant remember if this happened before I used combofix or not. I cant use a restore point cause I think it got removed when  I used ccleaner afterwards, trying to find out whats causing the lag.

I read in the rules that I think we're not allowed to discuss combofix. If that is indeed the cause problem(combofix) and we're not allowed to discuss it here, could you then at least point me to the right direction since I am really in need of a solution.

I'm running windows 7

http://www.bleepingcomputer.com/forums/t/535313/mini-periodic-lag-spikes/#entry3380039

 

Basically I copy pasted the description from my earlier post in the "Am I infected? What do I do?" section. I assumed it had something to do with malware. After some help from Broni, of whom im really grateful for, I still experience the lag spikes. I decided to completely reformat the laptop and start fresh with a new OS. Upon further testing I still experience the lag spikes whenever the temperature goes up. I didnt have this before I ran combofix. There could be other causes but I dont really know. I assume everything should be reset to default because this is a brand new installation of windows 7 ultimate. Could anyone please enlighten me? I wonder if there's something wrong with the processor.

You did not read such :), what you may have reference to is the fact that ComboFix and other tools used for malware situations...are not proper tools for discussion or use here in a forum which does not deal with malware or the use of tools designed for malware situation.

 

If you have questions about any aspect of ComboFix...I suggest that you post those at BC's AV/AM Software Forum, where the contributing members are more qualified to comment on questions about ComboFix and other AV/AM tools.

oh sorry, I shouldve ommited combofix. Anyway, do you know any diagnostic tools that could help me check for hardware problems? I ran a...I forgot the exact name...some kind of built in memory diagnostic and it just says "hardware problems were detected, please consult manufacturer".

 

The current status of that laptop is it just shows a black screen where the login screen should appear. My next move is to just reinstall and reformat to make the laptop work again.

edit: I also suspect that my laptop's hardware has also degraded due to the heat it produces. That is what my friend says. Im not really certain of the cause but this could also be another lead

Some laptops throttle performance based on heat, actually most new computers do this. Dust it out as step one. You can blow canned air through intake and exhaust ports (where the fan pulls in air and blows air out). You can also use an air compressor with low psi (40 or less). Make sure to disconnect the main battery and power, have the computer off when dusting out.

 

As far as diagnostics go, if you are not getting BSOD, I suspect your ram is fine. You could run MHDD which would test your hard drive for bad blocks or slow blocks... I will post that below since it is a long instruction set.

 

Also while you are at it, run speccy:

 

  • Go to Piriform's website, and click the big download.png button.
     
  • Next, click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version.
     
  • You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.
     
  • After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
     
  • Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
    p22004369.gif
  • Now, at the top, click File > Publish Snapshot
  • You will see the following prompt:
    p22004371.gif
  • Click Yes > then Copy to Clipboard
    p22004372.gif
  • Now, once you are back in the forum topic you are posting in, click the p22004370.gif button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.
  • Congrats! You have just posted your specs!

MHDD

 

If a hard drive has a smart status warning or the drive is questionable this test may be of use NOTE this test does not work with AHCI or Raid sata operation. It must be done with IDE, ATA, or compatibility mode:

 

Before running this test it would be a good idea to backup any data that you cannot afford to lose. This test uses the hard drive at 100%. If the drive is failing or has problems it is possible for the drive to fail suddenly especially during heavy use as this test will do. It is unlikely but still I recommend backing files up to be safe. Here are the instructions to run the test:

 

The first step will be to burn MHDD to a disc as an image (cd preferably). MHDD Can be found here: http://hddguru.com/software/2005.10.02-MHDD/  Click the Last version of MHDD, CDROM iso-image download and burn this file directly to a disc.

 

TO CHANGE SATA OPERATION: (You may need to use your keyboard arrow keys and enter key if you can not click to change settings).

After burning the disc, restart the laptop and start tapping f2 or f1 or delete right away to get into the bios. There you should see System Configuration, expand that by clicking the + button (or using your arrow keys and enter key). In that list there should be something called Sata operation. (Sata Operation may also be by itself in that first screen list)

Click on sata operation and take note of the current setting to the right it will probably be set to AHCI it will need to be switched back to this after MHDD is done running. Select ATA, compatibility or ide mode and then click apply. Save and exit the bios, or if apply was the only option you can use Ctrl+Alt+Delete to restart.

COMMON BOOT MENU/BIOS keys: https://support.fixmestick.com/hc/en-us/articles/201577043-How-to-get-to-your-Boot-Menu-or-your-BIOS-settings

 

Now with the burned disc in the drive after a restart, start tapping (F12 Dell, Toshiba, Lenovo), (F9 HP), or (Esc HP, Samsung, Sony) on the keyboard (or change your boot options to boot to cd/dvd first). This will bring up the boot options menu. Select cd/dvd/cd-rw drive and hit enter.

If this worked correctly and booted to mhdd you should see a screen that says Microsoft windows 98 startup menu. You can let the timer run out or just hit enter on option (2 . Start computer without SCSI support).

 

Now you should see a screen with numbers, most of these will not have any device listed behind them but one number should for example on my dell computer number 6 has WDC WD1600BEVT-75A23T0… and at the end a number in white which is the size of the drive.

Example: If your drive is a 500gb I would expect that number in white to be somewhere around 500,107,862,016 or close to. Find the correct drive to test then on the keyboard type the number in front of the drive (in my case it was 6) and then hit enter.

 

Now you should have a screen with MHDD> and a blinking cursor.

Now hit F4 on the keyboard 2 times and this will start scanning the hard drive.

You should be able to see the computer start scanning, each block represents 255 sectors (130560 bytes) on the hard drive. What we are looking for will show up on the right side of the screen.

There is a list on the right which shows numbers:

<3

<10

<50

<150ms

Etc…

 

Anything below the <150ms is a slow sector or a problem sector. Slow sectors <500 or >500 will slow down the computer. If there are a lot of these one after another (several 1000 or more) the drive should probably be replaced. Also if you have any at the end that were marked as UNC this means the drive has uncorrectable errors and the hard drive should probably be replaced.

Basically if you have any sectors that are below <150 (green) let me know and if possible the total number of them.

 

If all of the sectors were ok and fell within the range of:

<3

<10

<50

<150ms

Then the hard drive is ok, if there are only a few that are slow <500 or >500 the hard drive should be ok to use.

 

NOTE: that if there are many slow sectors one after another or you start having error after error the drive is in bad shape and I recommend ending the test. To end the test hit the Esc key.

 

After you are done testing you will need to go back into the bios by restarting the computer and tapping F2, F1, Delete (or whatever key gets you into bios). Go back to Sata Operation and change it back to the default which probably was AHCI.

Then restart and the computer should boot again.

(If you are getting a blue screen and the computer restarts go back into the bios and confirm that Sata Operation is set to what it was before changing it to IDE, ATA, or compatibility).

 

ADVANCED USERS: (USE AT YOUR OWN RISK)

There are options for fixing drives: erase delays and re-map bad blocks, enabling re-map is ok to do for most drives, no data should be lost. DO NOT erase delays if you have not backed up all of your data! These options are available from the F4 menu (only pushing F4 one time from the MHDD> blinking cursor screen.) Use your arrow keys to move up and down to highlight the option and hit enter to open and change the setting. Another useful key to hit at the MHDD blinking cursor screen is F8, this will bring up a drives S.M.A.R.T information.

 

What re-map does: This option if enabled moves available data from a bad block to a good block and disables the bad block by telling the controller to add it to a black list (list of blocks that the drive will not write to). This is a good option for drives that have available free space that have many bad blocks that can cause many problems including: BSOD bug check 0X7A etc. During a scan with re-map enabled a BLUE block after a bad block indicates succesful re-map.

 

What erase delays does: This option if enabled will erase blocks (and add them to the black list) that are slower than <500ms, if you have a lot of slow sectors greater than 20% of the total blocks, this is not recommended. If you erase delays on an OS drive or drive with any data, your OS may no longer load, your data may become corrupted. I only recommend this option on a drive that you intend to format and then re-use. Erasing delays can speed up a drive. The logic: 500ms = half a second. Each time windows tries to write or read from that block it takes half a second. Having a file written in 1000 slow blocks at 500ms (each block) would cause that file to take 8.7 minutes to read. 1000 blocks = 124.5 Megabytes. During a scan with erase delays enabled a white W indicates an erased slow sector. Slow sectors >500ms can significantly slow down write/reads depending on the actual read/write time for the block.

Reply to the first reply. Sorry I wasnt able to reply immediately. Just got on the laptop right now after a few days.

 

the result, Im not sure if this is the hottest that the laptop could get because Im not playing anything that takes alot of CPU resources.

the hard drive seems ok based on the SMART diagnostic. 

To add some more detail, I think I ran combofix (which I thought was the initial cause of my problem) due to a blue screen of death. 

I heard that a friend of mine received blue screens due to hamachi. I had that on but I couldn't remember if my first BSOD happened when I had it installed. My brother has the same laptop model and receives BOSD's too but does not have hamachi. He does not receive lag spikes like I do though when the temperature goes up.

Those temps are fairly high but not the max. I believe that chip throttles at 100C. If those temps are not doing anything cpu heavy, they are pretty hot. Idle temps should be lower. You could download and run HWmonitor and keep an eye on the temps.

 

If you have had any blue screens please download and run whocrashed:

 

We need to analyze your operating system's crash dump files to further diagnose what could possibly be crashing your computer system.

Please download Who Crashed? and save it to your desktop.

Double click whocrashedSetup.exe and choose Run

On Windows Vista, 7, 8 and 8.1 machines, when User Account Control asks if you wish to install this program, say YES to install the program on your computer.

Program can also be installed by right click and choosing Run As An Administrator.

On the next screen choose Next and accept the agreement.

Install the program in it's default location C:\Program Files\WhoCrashed (If your primary drive is different from C:, choose your primary drive.)

Choose Next and allow program to create a Start Menu Folder called WhoCrashed and click Next.

Allow program to create desktop icon and click Next.

Now Click Install.

Once the program is installed on your computer system, look for the WhoCrashed icon.png desktop Icon and double click it.

Accept the User Account Control request and the program will open on your screen and should look something like this.

whocrashed.png

Next, Click the Analyze button. analyze.png

An Information Window should appear on your screen prompting you to scroll down your screen.

If a report was generated we would like to have a look at this report.

To do this, click File analyze.png and then choose Export.

Save as WhoCrashedOutput.htm to your desktop.

Open WhoCrashedOutput.htm and copy and paste all of the contents from System Information (local) and Crash Dump Analysis and the Conclusion into your next reply.

will try this when I get home. I do hope the logs are still scanable.The last time I had a major crash was when the computer froze and the computer refused to start up anymore(a black screen appears where the log in screen should be). from my main installation, I reformated once and placed a fresh installation of windows 7. After the last crash, I just reinstalled windows without formating. I cant remember if I had a BOSD after the reformat.

how should the files look like in C:\Windows\Minidump? currently there are no files for the program to check in that folder and in the windows.old folder

I heard a rumor before that there was a certain virus that causes some of the hardware to overclock themselves or something like that...any truth to that? I dont see that happening though since I already reformatted my drive unless it stays somewhere other than the disk

There are some virus's that will use your hardware at 100% which will certainly cause lag everywhere. These are generally online currency mining virus's they use your computers hardware to mine something like bitcoin for the virus creator.

 

Since you have already re-formatted I doubt this is the issue. If you used a genuine windows disc to reload the os it will be clean. Sometimes using a hard drive factory restore partition will not work. There are a few virus's that can infect the restore partitions. I have only seen this 2 times.

 

The bsod dumps should be located in this directory: C:\windows\minidump

 

If the crashes only happened on the old installation, I don't know if they would have been saved. What data do you see in windowsold? If I recall correctly, windows will save the users folder, program files and program data. I don't recall if it saves the windows info.

 

If it does look in windowsold\windows\minidump, copy the files from that location and move them to your current C:\windows\minidump, then run who crashed and it should work with the old dump files.

There are no files in the windows.old\windows\minidump. I had 4 installations of the OS. The 1st one was the original one where I first encountered the problem, the 2nd where I re-installed the OS but did not reformat, the 3rd one where I re-installed again with reformat and lastly the current one after the 3rd one fatally crashed when running a game and caused a black screen where the login screen should be causing the laptop to be unusable. I just re-installed the 4th one, I didnt reformat. 

 

I reformatted after the 2nd installation and I dont think I received BSOD's during the 3rd and 4th ones.

The original problem happened after either a BSOD or running combifix after the BSOD happened. Not quite sure what the cause is. 

The lag spikes didn't occur before the 2 suspected events. 

Upon using Specy, the average temperature of the processor and motherboard when idle is 60-70 and goes straight to 100 when running games. 

Right now I'm thinking of sending the laptop to the shop to have it looked at. I suspect there might be something wrong with the fan since as you said, the processor throttles itself upon reaching a 100 temperature. I might also get an external cooling fan.

The most likely suspect after a fresh reload is hardware especially if your temp is going up to 100 quickly. Fans wear out and heat syncs get clogged with dust and hair etc. A shop may dust it out for free (the shop I worked in would) and this might solve the problem.

Hi, I had my fan cleaned and the fan exhaust seems stronger now, alot of dust was collected. I haven't really tested the programs I usually run for the lag spikes yet but I have used certain programs for testing the cpu load. While constantly at 50% processing speed, the temperature goes up gradually. The problem is, it doesn't go down. I haven't tested if it would reach 100 degrees Celsius but it reached 97. I checked around online what are the safe temperature levels for components and I saw that running above 90 degrees for extended periods of time is bad and I apparently do that alot. Is there a way to check if my processors or other components are below 100% durability?
