Do I have enough power?

[Euchrestalin]

I am experiencing nvdkllm driver crashes when gaming. I have already tried uninstalling the nvidia drivers using driver sweeper and reinstalling the newest version. This leads me to believe the problem may be that my power supply may not be providing my system with enough power during taxing operations.

My rig:
Intel Core 2 Extreme QX9650
EVGA 780i SLI
2x2GB Corsair Dominator DDR2-1066
EVGA 8800GTX
WD Velociraptor 300GB
Seagate 7200.11 1TB
2x Seagate 7200.11 1.5TB
PC Power & Cooling Silencer 750W
Windows Vista Business 64-bi

A fully functioning PC P&C Silencer 750 wouldn't break a sweat powering your system.

Perhaps your videocard is dying.

Definitely not PSU related. Unless its just defective

Tests you can run:
Memtest 86+ to rule out RAM
Some flavor of HD test to rule out bad sectors or something HD related
OCCT PSU torture test to rule out bad PSU

If those all pass make a partition on one of your HD's and install Win7 RC or something and game for awhile on that to see if it crashes too. If it doesn't, reformat time.

Absolutely enough power.
