Windows 7: Random BSOD

Back again with a new video card and same blue screens, but what are the odds that the second one is also damaged...

NOTE: I have severe eye problems. If I do not respond to your postings, please PM another member for assistance.

While it's possible that a second video card could have defects that would cause the exact same problem - it's not as likely as something else causing the problem (and the video card being good). As I said in my PM, I would next suspect the motherboard - but we'll have to check things out first.

The MSINFO32 file shows numerous different BSOD's. This is usually due to a hardware problem - but can be caused by compatibility issues, low-level driver corruption, or even malware.

Please rerun the video stress test that previously generated errrors for you (?VMT?) and see if it still generates errors. If it spits out errors similar to before, we'll assume that the video cards are good. The only other way to test the video cards is to stick them in another system (that isn't haveing BSOD's) and see if they work there.

Have you looked at your motherboard to see if anythign looks wrong with it? I'd also check for bad caps: Badcaps.net - How To Identify

Do you have an A=Rock overclocking utility installed (even if you're not using it)? If so, uninstall it as many of these utilities will cause BSOD's.

Uninstall all the system utilities and benchmarking utilities such as AIDA and CPU-Z, etc. They're cluttering up the results and we don't need them right now.

7 memory dumps from 25 Aug to 03 Nov 2011 (2+ months)
3 different BSOD error codes (0x1A, 0x4E, 0x3B)
4 different causes blamed
This is usually due to a hardware problem - but can be caused by compatibility issues, low-level driver corruption, or even malware

Here's some other stuff I'm wondering about:
- MalwareBytes AntiMalware appears in the dumps. Although I don't suspect it, please uninstall it to ensure that it's not adversly affecting the results.
- download a fresh copy of the Windows 7 drivers your your Linksys wireless adapter. Then uninstall the current drivers and install the freshly downloaded one's.
- Please uninstall MagicISO as one of it's drivers dates from 2009. Don't reinstall until we're finished troubleshooting.
- please do the following:

Anti-Virus Removal:
Please do the following:
- download a free antivirus for testing purposes: Free AntiVirus
- uninstall the ESET from your system (you can reinstall it, if so desired, when we're done troubleshooting)
- remove any remnants of ESET using this free tool: How do I manually uninstall my Windows ESET security product? - ESET Knowledgebase
- IMMEDIATELY install and update the free antivirus, then check to ensure that the Windows Firewall is turned on.
- check to see if this fixes the BSOD's
NOTE: NEVER run more than 1 anti-virus, firewall, Internet Security/Security Center application at the same time.
- I also wonder about your Etron USB 3.0 drivers. Is this a separate card that you can uninstall and remove from the system?

The above stuff is stuff that I'm not accustomed to seeing in memory dump files. This doesn't mean that it's bad - but removing it will eliminate it as a possible cause for the BSOD's.

Good Luck and let us know what happens!

Now I will go a little around what you have wrote above and get back to it if I will spot problems again, below find why.

I have found that when comes to memory testing it is adviced to test modules one at a time. Earlier I did like 48h of memory testing with memtest x86 and no errors appeared. Yesterday I decided to test the modules one at a time and one of them was fine after 6 hours of testing, then I have switched them and left it for another 8 hours. The second module reported two errors in the memory. I have removed the faulty one and look how PC will behave now.

Thank you for your support. I am really sorry that such a kind person with extremely large knowledge about computers is having eye problems, it has to be hard for you. This is most unfortunate. I hope you will get better!

Yes the issue is fixed. I had not a single bluescreen since I have changed my memory to the new one.

Advice learned from this one: always use memtest86 with a single memory module when testing. Then if no errors occur then put them back together and test again so you are sure then that everything is ok with the memory.

Thank you for your help usasma!

Thanks for letting us know your results! I'm especially interested in the testing methodology (1 stick at a time) and will suggest it in the future!
