Nv4disp.dll BSOD!

[Peskoly]

I was playing SC2 earlier today and randomly got a BSOD. It related the crash to the nv4disp.dll driver. I recently upgraded my graphics card to a 9800gt and i have the newest drivers. My computer has been running fine for the past month since ive put in the new card so i cant think of what the problem could be

Core 2 Duo 2.9ghz
3GB ddr2 pc5400 RAM
Coolermaster 500 watt PSU / +12v1 @ 18A +12v2 @ 18A
Asus P5N-D MOBO
EVGA 9800GT 512 MB

The only thing i can think of is the power supply not being rated high enough for it. Could that be the problem?

Also my GPU runs at about 56C when just using internet and what not but when im playing games it shoots up to around 65Cish

Could it be overheating and crashing??

Your PSU is more than enough and 65c is nowhere near overheating.

Go back one or two driver sets,, sometimes the latest drivers will not work properly with any given card, [for whatever reason], and ,, if you are worried about your gpu's temp take it apart and replace the OEM gunk with Arctic Silver 5 or something,also you could try reinstalling your current driver maybe it is a bad file, otherwise consider the above...
