Hey guys, new to the site and wanted to seek some advice on my computer. I am going bald pulling my hair out on this problem.

My system is a HP Pavilion Media Center TV m7470n Desktop PC.
2x 1gig DDR 400

My computer auto installed a SP3 update from Microsoft and my computer would not fully reboot after. It reboots and before it gets to the login screen, it says IRQL_NOT_LESS_OR_EQUAL. Also i have had PRN_LIST_CORRUPT.

I did a complete low level format and reinstall of windows, or tried to. It formatted and then began to install windows. Part way through I got the IRQL blue sceen again. I cant get past that. I know the BIOS has the most recent update drivers from the HP website. ( 03/03/2006-RS480-SB400-6A666M4DC-00-None Phoenix-Award)

I ran mem test and it came back fine... looped the test 12 times over night.

PC Test had two errors:
Memory 1 Microtopology Failed

Memory 2 Microtopology Failed
(All other memory tests past)


All other tests including motherboard and hard drive passed with no problems. I can run Linux Live on the CD but not load Windows XP. Keep getting multiple errors.

The last thing I did before the complete crash was the auto update of SP3 for windows XP and updated my ATI Radeon XPRESS 200 drivers from HP's website. (BIOS was updated a few weeks prior to these problems as well)

I tried new ram but same problems. Even tried shuffling the ram to the other two unused sockets.

Any help much appreciated!
