I recently built myself a new computer. Specs...

OCZ 4GB (2x2GB) PC2-6400C5 Dual Channel Vista Gold Series DDR2

Microsoft Windows Vista Home Basic 64-Bit

Gigabyte GA-P35-DS4 (Socket 775) PCI-Express DDR2 Motherboard

Intel Core 2 Duo E6750 "LGA775 Conroe" 2.66GHz

Asus GeForce EN8800 GT 512MB GDDR3 HDTV/Dual DVI (PCI-Express)

I am also using two 80 gig hard drives from my previous PC.

700w Power Supply

Ok basically this is what happens. I turn my PC on, it seems as if it is going to start and then... oh no. Off. The CPU fan does spin for about two rotations and then nothing and the whole things powers off. There seems to be little consistantcy to how long the powers srays on. Sometimes it's 1 second, other times the CD-ROM will spin etc and it wil go all the way to 10 seconds before powering off. It will continually power on and off in this manner if left alone.

It should be noted that sometimes if I poke around, unplug the power lead, reconnect and wait for a few reboots it does eventually boot up, the CPU fan will spin and I can use my computer confidently - as long as I don't turn it off.

Now this is what I've tried in varying combinations...

Re-seating the CPU, reapplying thermal paste
Changing the CPU fan with indentical fan
Unplugging all non essentials
Taking the mobo out and sitting the whole deal on a tea-towel to see if the mobo was shorting out on the case
Using an 8pin instead of just a 4pin in the power connector next to the fan.
Resetting CMOS
Shouting at it loudly and other threatening behaviour

Any help would be much appriciated, thanks alot.
