Warning light were? Is it the CPU one is listed in the manual is it showing crazy, high or normal?
Have you tried the PSU in another computer? testing each 8 pin connector for the CPU being that most don't need two.
Do you have both caps out and are are using two 8 pin connectors for the CPU?
Is the 4 pin molex next to the PCI-e slot connected from your PSU? Shouldn’t be needed but try it.
Your RAM is in the red slots?
Try Clear CMOS on the rear panel?
Thanks Peter for the reply here are the answers
Warning lights for CPU, DIMM, VGA etc are before the 24 power cable pin power connector.
I tried both of PSU (HX1000W and UltraPower 600W) and both are working fine in my old motherboard ASUS-M2NPV-MX.
Both caps are out. I tried first with 8 pins and then I used another 8 pins but CPU warning light is still there
Yeah RAM is in red slots, I also tried in black slots.
Did that but that wont work until damn CPU light disappear.
Take the whole motherboard out of the case and put it on some cardboard and then try powering it on.
Then take out the card and see if you get any beeps then try that for the RAM if nothing get the motherboard tested out at the and if tested to work ask to get the BIOS updataed.
I exactly did that this morning.. took out everything, double checked processor position. No beep, perform the GO test (Asus feature on board for testing individual components) The LED is just stuck on CPU, I wish if it could accept my AMD X2 Dual core processor so I can test the board.
