Power light and motherboard flashing

\015 Power light and the motherboard flashing amber\015

Answers :

Same problem - normally on a Dell the amber light states that the power source is working correctly but there is a fault with the motherboard. Normally the dreaded POST error. I have this problem with 2 Dimension C521s but one of them has a fried PCI-e slot and also overheating integrated graphics.
