if your running a new install of windows 7 Fully updated and the MB bios at the highest version out there
and when ever u run a game on high graphics and u get quite a fps drop and a Video card driver fail
could that mean your power supply is not strong enough and or is failing as the moment as the driver fails and restarts normally u can run fine still
sorry if that was a noobish question im from the old area were single core cpus Ruled.
1 ati 5870
1 250 gb hdd
1 1tb hdd
power color 650watt
There is no noob question. Asking questions is good. It 'could' be a power supply problem but it is not certain. 650W should be sufficient for your setup. Try updating the drivers, check the temperatures of cpu and gpu.
