New system , supplier gone bust! Powered up and immediately get 3 beeps, pause, 3 beeps, pause continuously. MBoard ASRock K78SX with AMI Bios. Any help appreciated. Thanks.

3 Beeps on AMI Bios is a Base 64K memory failure.

If the system has never worked I would first check the Memory, have you ever opened up a PC or are you confident with doing so? If not best to get a PC Tech to check this out for you. It's worth just checking the memory is seated correctly on the motherboard and if it is it could well be dodgy memory.

This type of error can sometimes also be down to other hardware components but unfortunately it's a case of troubleshooting your way through. I fthe companies gone bust perhaps this is why....
