HI all,

 

Thanks in advance for any and all advice.

 

Here's what has happened and what is happening:

 

While I was on a business trip my wife's computer was sluggish and eventually she got a BSOD. She attempted a reboot but almost nothing happened. When I returned home I tried to boot the system. The system got hung on the ASROCK splash screen before the POST beep. I tried a few times and got the same result. I noticed that I couldn't access a BIOS setup or a boot order screen either. I also notice that the keyboard lights were not flashing and the mouse was not getting power. I figured this was a mobo problem. bad news/good news. The mobo is a couple years old and I cannot find another to purchase. on the other hand, I built my kids' PC with the same mobo. So the plan was to cannibalize the kids' rig, replace my wife's mobo, and get a new mobo for the kids' PC. I would then do a clean install for the kids. They have lots less stuff to reinstall, etc.

 

So today I sat down to pull my wife's PC apart and figured "what the heck" and tried to boot it up. For some reason I disconnected the printer USB and moved the keyboard USB input to that port. Lo and behold, the machine booted up... Sort of. I got past the splash screen and was able to boot into safe mode. That was a plus, but everything was moving very slowly. So I tried booting normally and got in. I thought this was a victory, but everything was incredibly slow. I brought up the task manager and saw that the CPU was running at only about 4 - 7% and the RAM was pushing only 2.15 of the installed 4gb's. But just closing that task manager window took more than 3 minutes.

 

I decided to run a malware scan, so I installed Malwarebytes (took a while) and ran the full scan. The system found 28 potential registry problems, but a quick look didn't show me anything scary. I quarantined those and rebooted.

 

On the reboot I got a disk-read error. A quick CTRL-ALT-DEL rebooted the PC, but now I was concerned for the hard disk. So I pulled off a couple of important documents with password lists and such and set it to run a CHKDSK. It is running that check as I type this.

 

So here is my question: Does this sound like mobo problem? A HDD problem? a RAM problem? What?? I am confused.

 

My money is on mobo first and HDD second. I don't think it's a RAM problem, and why would a HDD failure of some kind cause the internet to move at a crawl? Unless it's something to do with the HDD being accessed to pull up the browser.

 

Any thoughts or advice is appreciated.

 

As mentioned, I have a new mobo on the way, so I can switch that out and reinstall if necessary, but if it's a HDD thing I don't want to waste my time on that.

 

Thanks again!

Hi,

Before I started replacing components I'd finish doing the security scans - 28 registry problems don't just 'happen'. Once I'm sure that the possibility of an infection is passed I'd start testing components.

Keep us posted

It looks like a failing HDD to me. If BIOS having issues detecting HDD, it will hang on the splash screen.

 

 

 

why would a HDD failure of some kind cause the internet to move at a crawl? 

 

 

Your OS , apps and everything is stored on the HDD. Also Windows requires writing to page file stored on the HDD frequently. Yes, the HDD do have a huge impact on system performance. That is why you will see a considerable performance improvement when you use SSD as the boot drive.

 

 

Please post a "Speccy" snapshot of your system by following the below guide.

Thanks for the replies guys.

 

I am at work right now, but when I left today, the CHKDSK was still running. That's over 12 hours. I set it to find and repair bad sectors as possible.

 

I will post a "speccy" pic when I return home today. Hopefully the HDD will be done checking itself. It doesn't look good, though. Luckily, my wife is smart enough to have MOZY backing everything up to the cloud.

 

Thanks again and I will be in touch.

I agree with other posts about the HDD being the problem. I have seen many bad hard drives cause hangs on post. Also if you had problems with usb ports not working, visually inspect all usb ports for shorting pins or damage...


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.

Thanks Zingo. The strange thing about the USB ports is that they work and then they stop. For example, I use a USB wifi adapter on this PC. The system connects to the internet, but on reboot that adapter goes dark. I switch to another port and it works.

 

That was one of the reasons I thought the mobo might be the issue.

One other update. The CHKDSK seems to be hung at the following point:

 

usn journal verification completed.

CHKDSK is verifying file data (stage 4 of 5)...

10 percent complete. (131952 of 231920 files processed)

 

It has been sitting at that point for several hours now.

 

If someone can tell me how to include a pic in this post I will post a picture of the screen

 

 

EDIT: I attached the pic

That was one of the reasons I thought the mobo might be the issue.

This might still have something to do with a failing hard drive. Chkdsk is not always accurate. I generally recommend a surface scan utility. The one I use to test hard drives is called MHDD. I will post the instructions below.

 

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).


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
