Windows 7: BSOD with System Service Exception, CLASSPNP.SYS

Hey Dave,

All the BSODs that ive had, the error line most commonly visible has been:
IRQ_LESS_OR_NOT_EQUAL

other than this one, i have never seen anything specific.

but i have an interesting discovery to share!

My windows finally crashed (due to many BSODs in the last 2 days maybe, or something Internet Download Manager did with my system files, i dono...)

Anyway, i had to install a fresh copy of windows 7.
A friend suggested me to install 32Bit windows 7 Ultimate, but i opted for the 64Bit one...
When windows 7 was installed, i could not find my motherboard drivers disk...
so i had to log on to the website to get the motherboard drivers for my system..
but i had installed MSE first....

i downloaded the VGA drivers from
ASUS - Motherboards- ASUS P8H67-M LE

Intel Graphics Accelerator Driver V8.15.10.2618 for Windows Windows 7 64bit---(WHQL).
and
Intel Corporation graphics Driver V8.15.10.2219 for Windows Vista 32/64bit & Windows 7 32/64bit.

afterwards, while i was updating windows, there was a BSOD with no specific error told...

i had installed ONLY MSE and then the VGA drivers when this BSOD occured..

is there something that can be done regarding this discovery?

Or shud i really try installing 32Bit ultimate windows 7??



thanks

now here it was...

i reinstalled the VGA driver with hotfix provided at the asus website.
then i went to start up menu and had the settings reset to default..
havent had a BSOD eversince...
so for me, i think the causative agent for BSODs, was the settings in BIOS that i had changed while trying to make the 'sata to ide convertor' work for my old IDE hard disk...

thanks a million for all the help guys!
now i will mark it as solved and i hope it stays that way

Cheers!
