New bsod. For me anyway

I updated my VIA drivers yesterday & got rid of kbdclass errors. Now when I reboot or shut down I get a bsod with, "drive power state failure". Nothing in event viewer, but info events. Any clues? Thanks BB

How to Use the File Signature Verification Tool to Find Third-Party Drivers
Check APCI is enabled in the BIOS.

It may be worth uninstalling the VIA drivers back and see if the problem goes away.


Thanks Guys. Think a clean install is in order. Have played w/drivers for last 4 hrs.
 Now can't get to BIOS, kbd not working till 2k starts? Any other suggestions? BB

Oopps I left off a "R" in my post, which makes a world of diffrence in the error message.
Stop  0x0000009F, 0x00000100, 0x85638B80, 0x85638B80, 0x85644B0
Sorry  BB
It seems as if I have a bad update w/my IDE drivers, not sure how to get out of it.
If I delete in device man. it'll install a MS driver when it reboots.
Thanks bb

I updated the drivers from ViaArena, in safemode. Still getting a Bsod stop error on restart or shutdwn.
& Kdbclass in event viewer. Will try the Abit drivers in safemode. If no go will format. Thanks BB
I uninstalled Photo shop7, Studio MX, & Screens & themes. At this time no Bsod or Kbdclass in event viewer.
So with fingers crossed, (MAYBE) happy days are here again.  Thanks all  BB
