This is just off the top of my head as I don't know the exact hardware, but you could try this: Take off the heatsink and remove the heatpaste that (I assume) came with it. Remove all of the paste from the CPU. Then apply some other, quality heatpaste, like Arctic Silver, thinly.
Reassemble and try again. It may be that the board has thermal protection in the BIOS and the processor is heating up and cutting out. This happened to me often with Gigabyte boards and AMD processors, until AMD revised the type of heat paste they use. The original stuff acted as more of a barrier than a conductor, until it had been heated up and thinned out, which of course couldn't happen as the machine wouldn't start.

Subject: [PCBUILD] New PC won't produce display
I am building my first PC. I have assembled the components list below.
When I attempt the initial boot, the computer produces no display
(monitor remains on stand-by) and no sound. The power supply fans, CPU
fan, case fans, and video card fans all spin. Also, the memory LED is
on. I believe the motherboard is bad. Is there anyway that I can
verify that the motherboard is bad before I return it? Could the
processor be bad, or would the CPU fan not spin in that case?
Gigabyte GA-8INXP Motherboard
Pentium 4 2.4 GHz 512K 533MHz CPU
Antec TruePower 430W Power Supply
Chieftec DX-01BD Case
Centon 512MB PC2100 DDR
ATI Radeon 9600 Pro Video Card
I have also attempted to boot the PC with BFG GeForce4 TI-4600 and ATI
Radeon 7500 video cards.
