Hi all,

Here's my computer stats:
Vista 32-bit
Intel® Core™2 CPU 6300 @ 1.86GHz
1Gig Ram
Nvidia GeForce 7900 GS
Creative Sound Blaster Audigy


Okay, so it started about a month ago. First, my sound card stopped working. Usually, a restart causes it to work again. Then, occassionally I'd get this windows security message in my taskbar about not having any anti-virus running, even though my AVG free was running. I assumed it was just windows not recognising it sometimes, because the security message doesn't appear all the time. After about a week or two, the security message became permanently there. Again, i just ignored it, because my AVG was running perfectly fine. However, a few days later, while browsing the web, the computer just died. Screen went blank, and the power button blinking orange. Restarting the power and everything didn't work, it refused to start. Since it was still under warranty, i called up Dell and they sent someone done. He replaced the motherboard, and it could work again.

Just a few days after that, the same thing happened, just died out of nowhere. So, i called up Dell again. This time round, when they sent someone down, I wasn't able to be there, but from what i can see from the details of work from the receipt, he replaced the power supply, flushed and upgraded the BIOS. (From 2.3.0 to 2.4.0). When i came back and checked the computer, i realised my sound wasn't working anymore. Device Manager didn't even detect the sound card. Since the sound card is already around 4 years plus old, I thought it had spoilt, so I just removed it and used the onboard sound. (I tried plugging the sound card into the other PCI slot, didn't work either. And my sound card is my own, and therefore not covered under the warranty.) Less than a week later, the front port which i use to plug my speakers in to the onboard sound, stopped working. Only the one on the back worked. It was around this time that the permanent security error of not detecting any anti-virus came back again.

I called up Dell again (I bet they were really fed up with me by now. :thumbsup: Haha) and they sent someone down again. On the evening that he came, when he started up the computer, AVG didn't even load at all. Tried running AVG directly from it's folder didn't work either, it just refused to run. Also, it was at this point the technician realised that he couldn't download anything using IE. The downloading screen will come up, but when the download finishes, the file will not be anywhere to be found. I'm not sure when this started, because I use google chrome. Also, he tried replacing the front USB hub, but the front sound jack still didn't work. At this point, he recommends a reformat and states that he cannot help anymore because it's more than likely a virus or software problem. (That isn't covered under the warranty either.)

So, I bought an external hard drive, and backed up only my essential things and reformatted. I scanned the external hard drive with AVG before i transfered the things back, and it was clean. For some weird reason, my sound card didn't work right after my reformat. It was only after a few days later, when i decided to put the cover back on onto the CPU that it worked.(I have no idea why i even left the sound card plugged in when i put back the casing cover...) It's been less than two weeks since the reformat and now the problems are coming back again. I saw the security message about no anti-virus, even though AVG is running. A restart later, the error was gone. Then for the past few days, my sound card has around a 50% chance of working. Sometimes a restart makes it work again, sometimes not. More often than not, it starts out working, then after a few hours or even a few minutes, it just stops working. No errors anywhere or anything, just no sound at all. (This refers to both the sound card and onboard sound)

Earlier today, i downloaded Avira Anti-vir personal. A full scan doesn't show anything at all. I've been scanning with AVG free and Spybot every few days since the reformat. AVG free hasn't detected anything so far. Spybot just catches the usual spyware and removes them without any trouble.

Thanks!

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click mbam-setup.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Ok, lets run one last scan just to make sure that this isn't malware.

Please do an online scan with Kaspersky Online Scanner

Click on Kaspersky Online Scanner

You will be prompted to install an ActiveX component from Kaspersky, Click Yes.
The program will launch and then begin downloading the latest definition files:
Once the files have been downloaded click on NEXT
Now click on Scan Settings
In the scan settings make sure that the following are selected:
o Scan using the following Anti-Virus database:
Extended (if available otherwise Standard)
o Scan Options:
Scan Archives
Scan Mail Bases
Click OK
Now under select a target to scan:
Select My Computer
This will program will start and scan your system.
The scan will take a while so be patient and let it run.
Once the scan is complete it will display if your system has been infected.

Save the file to your desktop.
Copy and paste that information in your next post.

Hi,

So sorry, but the scan is taking a very long time and at this rate it's going to take a few more hours to complete and I can't wait that long. I'll be leaving my computer on and posting the results in probably 8 hours or so when i wake up.

Two things though... When i tried to turn on my computer today, it hanged twice at the windows loading screen. The third time, it started normally, but took a very long time to log into the account. Also, before i started the scan, the computer was rather laggy and slow. It then proceeded to deteriorate over the next few hours. (I had started the scan soon after the lag though, so I'm not too certain if perhaps the scan is the reason. Though it wouldn't really explain why the computer is getting progressively slower. I'll probably find out in the morning.)

Ok, I will wait for you to post back the scan results, and then if nothing is found, give some things that might speed it up a little

Hi,

So sorry, it seems my father turned off the computer while I was sleeping... I'll have to re-run the test again. Also, it seems the lag should have been due to the scanner, because the lag is now gone.


Edit: Hmm... I just asked him, and it seems that he when he turned on the monitor, there was nothing running. Obviously, if the scan had been still there, I'm sure he would have seen it.

Since this doesn't appear to be related to malware, I would suggest that you start a new topic in the Internal Hardware section of the forum where someone will be more knowledgable about a solution to your problem, as your problem appears to be with your internal hardware, not malware.

You could copy and paste your first post in this topic, and then start a new topic at this forum:

http://www.bleepingcomputer.com/forums/f/7/internal-hardware/.

Make sure you say that you know it is not malware related.


One more thing, please post a link to your new topic that you posted in Internet Hardware forum back on this topic.

Thanks
