Over the last week a problem has begun to develop on my computer. I will recieve momentary freezes on my computer while playing Call of Duty 2, C&C Generals, etc. At one point it began to occur every 2 to 6 seconds. Essentially what will happen is the game will just freeze and you will hear a buzzing sound. At the same time that this is occuring my Video Card is overheating. I have a XFX nVidia 6800gt. A while back I over clocked it to about 370 and 1.02 (from a stock 350-1). Unfortunately I did this with a stock fan. I am wondering if this is coming back to haunt me. WHen I play CoD 2 the video card gets to about 108 degrees. I tried underclocking it and the problem did improve slightly. However, on top of all this I am getting random crashes on my desktop and have also recieved the blue screen of death with the following message-IRQL_NOT_LESS_OR_EQUAL. I googled that and didn't get anything helpful. Is there a possiblity that it could be a virus? Or did i just screw up my video card? lol. Well any help would be appreciated. Thanks bunches.
