In a PC I am fixing for a friend, I have a problem where I turn on the power it begins to boot for 5-10 seconds, emits a series of beeps in no discernable pattern, but also not continuous, then powers itself off.

Brand new 300watt PSU
AMD Duron 750
512Mb SDRAM PC-133
ATI Rage Fury Pro 32MB
56K
10/100
ATI Video Capture Board and tuner

Took system down to CPU, RAM and still had the problem. Tried Ram and CPU in different machine and they worked fine, tried the CPU and RAM from my personal machine in the ABIT board, same issue.

Am I looking at a bad board or am I missing something somewhere?

Any help or insights would be greatly appreciated.
