Have an old Socket A XP 2400+ on an Abit KR7A (or RAID version as has chip) motherboard.

Basically it has been formatted three times now, and it works for around a week before locking up when turned on or rebooted. Or a few minutes later

Boots to Windows desktop (XP Pro SP3 with updates) and get ballon tip in system tray "Your computer might be at risk" because the anti virus has not been updated since leaving me (as not been online). Usually locked up before able to do anything as can't move mouse cursor or use keyboard short cuts/turn off numlock (tried USB and p/s2)

Only problem I found was memtest fail on test 5, but have read it may be an issue with the motherboard chipset and type of processor. Latest Bios has made no difference. Have tested RAM in another system and it was fine. Tested known good RAM in this and it also failed on test 5.

There is nothing in event logs, so after suggestions on what to try to trouble shoot it.

Don't have another AMD system to try swapping CPU with. Or a spare PSU to try.

Edit: Doesn't seem to be always which is the annoying thing. Has been OK while I've typed this, and now just running MSE scan to give it something to do. Processor is a Thoroughbred core 2400XP (not sure if A or B)
