Hi all, my friend has a computer that every so often reboots for no reason, it did it yesterday (monday) and last thursday. I have the mini dump file but I don't understand it that well and wondered if anyone can make sense of it. Cheers

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 00000000, memory referenced
Arg2: 000000ff, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: e1491c68, address which referenced memory

see if this helps:

start -> run
"sfc /scannow" (without quotes)

then put in your XP CD

basically, it checks all the Windows files against the ones on the CD to make sure they're not corrupt
 
Thanks I will try that although the computer has just been formatted and had a clean installation of XP so I don't think that will be the problem. The problem was occurring before the installation as well so that is not the cause either.
 
I have downloaded it I just haven't tried it yet, I just remotely connect to their PC and ran PC Wizard to check the CPU temp and Fan and all seemed to be in order, the CPU is running at a fairly low temperature of 38C and the CPU Fan is running at a decent RPM.
 
It could be a mobo problem google your mobo model to see if it happens on that model I've heard of that once on some models something with the chipset don't remember well.
 
Well it has recently had a new motherboard but when I try to look at what motherboard it is it says: Unspecified P4V88+
