Hi all,

My PC suddenly showed following problem.
Problem: After power on, BIOS got 1 long and 3 short beep and there is no display at all.

As BIOS is AMI, checked web and most of them said this could be memory problem, but the same problem persists even changed with different memory.

Key parts:
Motherboard: Asus P5PL2 (AMI BIOS)
Video: RadeonX1800CrossFire (PCI Express)
Memory: DDR2 667 1 GB x 1

I have tried
1) different memory/slots
2) removing HD, DVD, video adapter and left only with CPU and memory
3) different LCD/CRT.

I don't have an additional PCI express video adapter to try but I don't think the problem is in video adapter itself cos it still gave 1 long and 3 short beeps even I took out the video adapter. It looks to me that motherboard might have problem here but want to hear you guys opinion. Thanks in advance!

PS: PC was self-assembled around 6 months ago
