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

windows 7 ultimate 64 bit
 
 

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 Win7 64bit---(WHQL).
and
Intel Corporation graphics Driver V8.15.10.2219 for Windows Vista 32/64bit & Win7 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!

HDD controller BIOS settings corrections or boot manager repair?

Hallo, I’m trying to transfer the operating system, due to the lack of space on a SSD, to a HDD and I’m encountering a BSOD.

Print screen BSOD: 0x0000007B (0x80D86B58, 0xC0000034, 0x00000000, 0x0000000A)

Short video sample: start-up to BSOD

It’s an OS back-up image made with Acronis 2013 (Windows 7 Ultimate 32 bit + updates to day) that I’m trying to restore on another PC.

About the hardware it’s a downgrade

from
Intel Core i5-4440, 3.1 GHz / ASUS H87-PRO / Crucial DDR3 (2 x 4GB) 1600Mhz / Gigabyte Geforce GT 640 2048MB GDDR5 / SSD SAMSUNG SATA3 50GB

to
Intel Core 2 Duo E6600, 2.40 GHz / ASUS P5LD2-SE / Kingston DDR2 4096 MB / Nvidia Geforce GT 430 / Western Digital Caviar Green 2TB SATA 3 (WD20EARX)

The idea is that the first was BIOS> AHCI (for SSD), while the second is BIOS> SATA (HDD) and I think the restored image contains some BIOS conflict information from the previous PC.

I changed the actual BIOS IDE config > Onboard IDE from “Enhanced” to“Compatible” and I got “No IDE Master HDD Detected” and then NTLDR is missing (booted from the partition with Windows 7, it's a dual boot with XP)

In safe mode drivers load until CLASSPNP.SYS, then blue screen appears for less than a second and then it restarts.

I tried a boot repair through the windows 7 DVD; it has found something wrong but in the end couln’t solved it; Also I tried with command prompt but I think I didn’t input correct choice of lines

Here they say that it would be rather a matter of AHCI / SATA


Any suggestion would be highly appreciated
Thanks
