Windows failed to load b/c driver is missing or corrupt


New Member
CMOS battery died. XP got corrupted somehow. I d/l'd Windows 7 Ultimate ISO from MSDN and made a bootable dvd. Installed Windows 7 from the DVD. When I boot up now, I get the following error:

Windows failed to load because a critical system driver is missing or corrupt.

Status: 0xc0000098
File: Windows\system32\DRIVERS\ql40xx.sys

Can anyone shed some light on how to resolve this?

Go to website of that company and try to download driver.

You may have to use another compter and download to a finger drive etc.
Once you have it, you can boot from the Windows DVD and try to install.

Alternatively, you can go to device manager, under view, check show hidden drivers. If you find one with a yellow marker, you can try to dowload from there.
