recently installed an 8800gt an began receiving system crashes, initially thought the card was to hot but now ive did some research and someone has mentioned that installing a new more powerful video card can also increase CPU usage and in turn heat, which also increases ambient temperature leading to a nasty chain reaction and a system crash. I'm using hardware monitor while running prime 95 and this alone is putting my CPU to 79 degrees. This is approaching safe limitations an x2 6400 isnt it? When I stress test the card and the cpu the system crashes.. im using stock coolers but this still should not be happening my system is well ventilated. any tips or possible other reasons for this problem?
