Hello,

I have just built my own pc and have gone to power it on, the power comes on for about 3 - 5 seconds before it goes straight off again. After a few seconds (without user intervention) it tries to power on again and does this continuosly until intterupted.

I have tried taking out and returning the RAM,processor and graphics card with no success.

Does anyone know what it could be?

Its a core duo 2.4, Saphire 512 Radeon 1900XTX and 2GB of 800mhz Geil RAM.
the motherboard is Gigabyte GA_965P_DQ6.

any help would be greatly appreciated
