Hi I have assembled a new computer a week ago and have been having at least one BSOD a day ever since. I run memtest86 overnight, 7 passes finished without any errors. I also run CPU and GPU stress tests, as well as checkdisk, none of them revealed any problems. Nearly each BSOD had a different bug check code. The first BSOD was during Windows update, and broke .NET installation. The following ones were during just about every activity. Gaming, video, computer being idle and locked at night, etc. I have performed a clean Windows installation, but this didn't solve the problem. I tried disconnecting the wifi module that caused some problems with my previous computer (couple problems in a few years, not much), and used ethernet connection instead, but no luck. The last BSOD in the archive happened when using ethernet. I use Windows 7 64b Here is the archive with 4 minidumps that happened since the last windows installation. Thanks in advance.
