CUDA Crash

Hi have had this problem for awhile now and starting to think its my hardware causing the problem. My problem is whenever i use a CUDA enabled program it will crash my computer. Only information i have is this.

Display driver nvlddmkm stopped responding and has successfully recovered.

4101 3 0 0x80000000000000 70503 nvlddmkm

this has happened on vista,xp and windows 7

at first it was bsod now the display drivers recover and the program fails.
