MATRIX GTX580/2DIS/1536MD5 Help please!?

Hey guys, my mates MATRIX GTX580/2DIS/1536MD5 graphics card seems to be crashing his BF3, he has a 500 watt power supply and he thinks this is the problem, I just need to know if this is is actually the problem before he goes out and buys a new supply, (even though he is well due for one) I just dont want him buying one and still having the problem. Any ideas?|||Simply upgrade the driver for the graphics card first. You can download the latest driver from http://www.nvidia.co.uk Also, make sure that all updates for his operating system and software are installed. The power supply should be fine, although 600W would be better most likely.
