Hello, again!
I've been meaning to post an update to my situation here. Thanks a lot for your reply, it's greatly appreciated.
I think I have to explain the situation's background, the context of this BSOD.
Since late December 2009, I installed Windows 7 x64 Pro. Back then, I installed all the latest drivers I've found for my hardware and all the software I require. I do not use any specific firewall software, just the included one from Windows. As an antivirus
I installed Avira Antivir Personal.
In the first weeks, I also tested a few games to see how the system fares. So, until April no problems occur, of any kind, no BSODs, no freezes/locks. Of course, poorly coded applications crash at times, in certain conditions, but that is unrelated to the OS.
I should also note that I did not install any additional drivers since January or any new devices. I also did not upgrade/change any drivers.
Since I installed Windows, I've enabled Windows Automatic Updates. Given the media coverage of latest Windows Updates which caused numerous BSODs for systems which were running fine, I started to suspect myself as well the updates which were installed by Windows.
Before jumping to any conclusions, I ran multiple PC burn-in tests for CPU, GPU and other devices to find any possible problems related to hardware failure. All the tests were succesful, no BSODs occured.
Having no other choice, I uninstalled all the Windows Updates of April 2010 and the last two from March 2010. Since then, that's one week already, no more BSODs occured :). This is troubling, because I would really like to use Windows Updates and it seems Microsoft
pushes unreliable updates. Here's the list of the updates I uninstalled: KB980302, KB980182, KB981433, KB979683, KB980232, KB890830, KB979309, KB978601. I have no idea which one causes the BSOD in my case. I've read their descriptions to try to figure out
which one would be the cause, but no luck.
If you know which update causes the BSOD, please let me know.
So, to conclude, the solution to stop having BSODs was to uninstall all the Windows Updates of april 2010 and to deactivate Windows Automatic Updates. For now, I do not intend to use it anymore. It seems that one never has to fix a system which runs fine :).
Best regards,
Marius
