Ok, so i added new ram and a new processor to my computer a few months ago. I had a 8600Gt video card in it at this time, and i was having problems with trying to play video games on it. It'd run the game for few mins then my screen would flash and then go blank. The sound was looping still tho, and the cpu was running but the monitor would say no signal. So i thought it was my graphics card so i bought a 9800 GTX and installed it. Well the problem stopped for awhile and now its doing it all over again. Idk what to do ='(
