Scanning didn't show any infections. And i got few more blue screens.
System is stable so far. I hope i fixed it myself.
Here is what i've done to him. Source > Google <
CPU what my pc is using is not working very well with RAM memory freq. 1600MHz. (Especially when CPU is OC like mine) So i went to BIOS and set freq. for RAM to 1333MHz. So far no blue screens..
System is stable for more then 2 days. I really hope this problem is past for me!
I'll mark later this thread as solved, want to be sure in this.
Be back here in 1 week. Hope not sooner.
Thx for all help guys.
