Here are the specs of my current setup:
*GIGABYTE GA-MA770-UD3 AM2+/AM2 AMD 770 ATX AMD Motherboard
*BFG Tech BFGE450WPSU 450W ATX 12V v2.2 Power Supply
*Mushkin Enhanced Silverline 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 996557
*AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor ADX6000CZBOX.
*EVGA 512-P3-N862-TR GeForce 9600 GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card (I have tried booting with and without this. It gives the same result - no POST beep. I have no other video card to test this with and my motherboard doesn't have an onboard one. If necessary, I might be able to try this in the other computer, but I'm not really thinking it's the problem.)
Edit: I've also tried clearing the CMOS with the jumper and taking the battery out for a few minutes.
