BSOD - Driver?

Hello all :)

Hi - I have started getting BSOD when running apps.

BSOD Suggests driver issue. The error messge is:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

also mentions uguru at the end of message (motherboard is abit ip35pro)

I have uninstalled uguru now and still get the error.

My Nvidia 8800 gts has the latest drivers (8.17.12.5721) (Vista 64 bit) - I am wondering if they could be the cause, but i don't have the previuous drivers to roll back to.

Any ideas how to decipher the code. I have latest Windows patches and have not installed any new hardware. I did reset the BIOS recently as system would not boot (power would only come on for a second).

Strangely i seem to lose some settings like desktop resolution and web pages dont remember my passwords after the crashes.

The memory.dmp file (converted to word) has this in it [I have cut stuff out that repeats] - again mentions uguru.
