View Full Version : MSI K7N420 M/B and Windows XP Errors

10-08-2002, 08:45 PM
I am configuring a new machine:

MSI K7N420 Pro Motherboard
Duron 600 (not o/ced)
Seagate Barracuda IV 40GB
and standard CD-RW and FDD

Everytime I try to install windows (any version) I get problems with the installer crashing on IRQL_LESS_THAN_EQUAL errors.

I am at my wits end with this problem, and am considering a BIOS flash as a last resort....

Anybody out there familiar with this problem or have any suggestions, I have changed all the BIOS settings in many different combinations without sucess.

Recently i have purchased a MSI board (KT3 Ultra ARU) and experienced the errors you are receiving. The problem being that the videocard is sharing a IRQ with another device. It is a known issue, expecially with NVidia based videocards.

Take a look at the following URL's, as there is some interesting info on this problem with possible sloutions.
