Everything is at stock - voltages, freq, bios settings
This usually happenes:
I run prime95 - no errors for 10-20 min and then system crashes. Just black screen and restart. However, if i start prime95 and launch some application while its running (like chrome, player, game, word...) - instant crash to black screen. No bsod, just black screen. And no errors in prime95.
Same thing with OCCT and IBT.
I also ran x264 encode for about 30 min and it worked great until i launched vovie player (mpc-hc) - instant crash
-CPU temps are ok - 45C under full load
-there is no dust in pc case
-i checked if all power connectors were plugged to mbo and gpu.
-I ran memtest - 0 errors
-i flashed bios to older version
-i upped voltages to northbridge and ram
I have no idea why is this happening. Here is log from OCCT power test. Ignore the dip in the mid, I accidentaly alt-tabed from occt.
8350, 990xa-ud3, kingston-1600 2x4gb, xfx-550w, msi 7950 boost, win8.1 x64. All latest drivers and win updates installed.
Tell me if you need me to post some other stats like bios settings, hwmonitor etc.
