[QUOTE=rolandc5;2516870]cant be the GFX card because i just got it a few months ago, i ran dxdiag it says no problems found. my video card is not overheating at all it runs at 56C at max and 48 at idle[/QUOTE]
OK then check into getting another PS since you say the GFX card isn’t overheating. I had a problem
similar to what you are experiencing a few years back with an ATi card and it wasn’t overheating or
dxdiag didn’t report and thing wrong either but I replaced the card and the trouble just went away.
To be certain it was the GFX card I tried it in another system and it started having the same problems
with the blank/black screens pulled the ATi card out and replaced it with the original and problem gone.
But both systems had really good PS’s in them at the time so it could very well be that your Bestec PS
is what’s causing all of your problems. I believe I’d be looking for another PS and stay away from all of
those no name PS’s stick with a brand name PS like Antec or Corsair, Thermaltake, SeaSonic, Enermax
PC Power and Cooling, Zalman. etc., etc,.
