My motherboard (copying off the box) is an ASUS A8N-E (Socket 939 for AMD CPU, NVIDIA nForce4 Ultra, Advanced Overclocking Features).
Power Supply is only 450W I think
The video card is a BFG 6600GT OC 128MB PCI-E (According to the old bill I have lol anyways its nvidia I believe)
Gig of RAM and 300gig harddrive
hopefully this is enough, Im not much of a computer junky...hence why I'm here lol
edit: paper clip test, something like this? How To: Jump Start A Power Supply (PSU) / Test A Power Supply And Components - Overclock.net - Overclocking.net
