Hi All,

I have been having an intermittent fault with my PC which has now become permanent and I'm wracking my brain to resolve it.

Firstly - PC Spec
AMD x64 X2 AM2 3800 CPU
ASUS AM2 Nforce 570 mobo
Nvidia 7600GT 256 video card (Point of View is the manufacturer)
1 GB DDR2 667 ram
250GB SATA2 Seagate Barracuda HDD
80 GB ATA133 HDD
DVD writer
Thermaltake Soprano case with stock thermaltake 430W psu

Symptom:
On Powerup system starts to power up - fans start (2x120 mm case fans, chip fan, GPU fan), hdd's start, DVD starts - then before POST whole thing shuts down.  No bios beeps - nothing.  I don't get the GPU POST or the system POST.

I've done everything I can think of
* Undo and reseat all cards and cables - test - same problem
* disconnect all DVD and HDD (only mobo, ram and video connected) - test - that worked lat the beginning of the week but fault recurred last night.  Redoing all tests so far doesn't work.
* Removed and reseated ram - test - no go.

I'm not sure if I have a PSU issue (fail or too much connected for the rating of the PSU), a graphics card failing, a ram card failing, a mobo fail or a chip fail.  I don't have the hardware (this is my only pci-e system and my only sata capable system) to swap out components to isolate. 


Oh... and the warranty expired in November :(


Can anyone suggest anything else I could do to troubleshoot this problem?

Cheers
James.
