Have you been recently infected? Have you run a security scan recently?

Hello Route44

No computer wasn't recently infected, and yes i did the security scan and didn't find anything suspicious.

Do the following: Start > Run > type in EventVwr.msc > Okay

Please note any Yellow Triangles and Red Xs.

No errors or warnings in whole event log (application, system or security part) before BSOD.

Hmmm, okay what make is your harddrive? By your error codes we are going to need to do standard yet important hardware diagnostics.

I already did hdd and ram diagnostic tests - no errors found. I did't attached new hardware or any new drivers installed. It seems more like some software problems, but i can't find what
