OK it's been a while and the MB didn't go back to China since it started behaving again... Four years later and it has started playing silly buggers again. Problem is it starts up but the MEM TEST light remains on and no beep - when I get a beep the MEM TEST light goes off and the computer boots normally.
Now when it doesn't boot and I have taken all the RAM out of the machine and re-boot it up sometimes I hear the warning beeps (continuous since no RAM detected) and sometimes I don't. This to me sounds like it is not an actually a RAM chip problem but some form of intermittent fault on the board in that sometimes it doesn't look for any RAM and just sits there. Then I find that if I either take all the RAM out and put it back again it will boot or if that fails just unplug everything, plug it all back again and then it boots.
I really haven't got a clue why this is happening but new mobo/RAM/CPU are on the cards, but I would really like to know why this machine does this periodically and then goes back to normal BIOS?
