BSOD doing anything, IRQL_NOT_LESS_OR_EQUAL, Stop: 0x0000000A

I have asked other people to have a look here ....

Given the error codes i feel it would be wise to run full hardware tests on the system
As arc mentioned memtest is an important one and needs to be run overnight for many passes to be sure RAM - Test with Memtest86+ i know you mentioned running it before but how many passes/how long did you run it for
Also HD checks would be good Disk Check and Hard Drive Diagnostic Procedure using something like SeaTools | Seagate
and a general system stress test Hardware - Stress Test With Prime95 to load up the cpu but again monitor temps at all times while running and dont leave unattended

If you have installed any special keyboard software, uninstall it while testing. Software from Netropia Corp is a known cause of BSODs on some systems. Also carry out all the hardware tests prescribed.

Lets start with this then.
RAM (memory) test:

This will require memtest on a bootable CD or USB stick.
RAM - Test with Memtest86+

So my sticks are failing in all four slots, is it safe to assume it's a bad motherboard?

Yes, I would also assume the same.

A bad motherboard can cause any type of issues. All issues are justified for it.

For a compatible and affordable board, Britton30's suggestions will be valuable. He is offline now. Hopefully he will suggest something shortly :)
