XFX MB-750I + q9550 Quad Core = absolute instability ,Lockups. HELP!
Hey guys! I came across with some instability over my system..its been going on for years, so I simply not used my PC for months because of that. Check my specs. I heard about something about compitability issues between Quad cores and XFX 750i, but now I have no video signal randomly from my video card, sticked into XFX Mobo.
I have checked the other thread replacing my xfx nforce sli 750i mobo: Advices
Now I even cant access BIOS, no video signal..so easily changing voltage for the core would not be that easy.
First. My video card is not burned and works normally on different systems - have checked it elsewhere.
Second. The system and OS had been randomly working for hours and days..with both Stress test on video (FurMask) and on CPU applied (prime95) for 10-15 minutes = no mistakes,errors or freezes. (Even though the other day, it did freeze)
Third. All parts of current build mounted on different systems worked just fine, as usual, no BSOD or anything.
Fourth. Dishonored and Battlefield 3 games were running on it Maxed out with out lags, just randomly freezing and randomly running for hours.
Any advises what to do?, Currently no video signal is present + randomly appearing to give access to XFX screen logo or bios, sometimes to Windows in Safe Mode, but no stable user possibility of using PC.
Honestly, unpredictable mysterious behavior of my PC.
