Too many BSODs, too little time...

Hi folks,

My brother's computer recently bit the dust while he was at work (much to my chagrin he leaves it running almost continuously for no particularly reason) and in trying to fix it I've uncovered various BSODs which come and go, but invariably full XP refuses to load. It dies either whilst loading, or when you attempt to log in. Safe mode boots but only after I already tinkered with a few things.

The spec is as follows:

Athlon FX55
1GB RAM
Leadtek 7600GT
200GB Maxtor
Asus A8V

Initially, the computer wouldn't boot to XP at all but having disabled all but two of the USB ports, underclocked the CPU multiplier to 12x and unplugged the DVD drive (a CD writer remains) safe mode now seems largely stable (I was able to run a disk defrag but when networking is enabled it BSODs).

I've run memtest86+ (1.6) and it comes up negative for errors (I it continuously overnight and apparently no problems).

Some of the BSODs are: NDIS.sys, nv4_mini.sys, USBPORT.sys

Haven't seen USBPORT.sys since disabling most of the usbs, and NDIS seems to be the most common cause, combined with the added instability of network safe mode could the onboard LAN be at fault?

Otherwise, I'm suspicious it might be a PSU problem as this would explain
the variety of errors and apparently unfaulty RAM. Looking in the BIOS setup the VCORE seems to be fluctuating a little but having never checked before I don't know if this is normal? The readings are as follows:
VCORE 1.4~1.55
3.3V --> 3.264V
5V --> 5.107V
12V --> 11.840

Any suggestions as to how I might fix this would be much appreciated!

Many thanks.
