I've just built a new PC with the following specs;

Case: X-QPACK-GN (with 420 watt powersupply)
Processor: Intel Pentium 4 BX80547PG3000F LGA 775
RAM: GEIL DDR2 (1 Gig)
Along with the DVD burner and a 250 gig HD (which I think are unrelated to the problem)

The problem that I'm having is that my computer won't fully power on. It will start to boot and then shut off, only to shut itself back on. This will repeat until I cut the power. This wasn't happening when I installed windows, and shortly after I installed windows, it would boot fully, but then shut itself down (i.e., say "Windows is shutting down" or whatever as opposed to just powering off.

I initially thought that I had improperly installed the heatsink or the thermal pad just wasn't doing it's job, but now it's shutting off before I think it has time to even heat up.

I'm also wondering if it's a faulty PSU or perhaps I damaged something during installation.

ANY help is greatly appreciated!

If you have access to a different PSU, I think you should try swapping them and see if the problem repeats itself. Additionally, if you have backup hardware, then try replacing each and every component to see if the problem re-occurs.

I also recommend having a look at the power connectors. Have they been properly seated on the motherboard, gfx card (if needed), optical and hard disk drives. Basically test everything, item by item. If nothing goes smoothly, then I'd suggest that the motherboard has been compromised somehow.

Good luck
