Any ideas what this could be?

So I have a HTPC that sits in a closet. The rig is as follows;

Asus A8N-SLI mobo
AMD 3500+ cpu
2GB RAM
ATI HD 4850
Antec 430w PS
1 80GB HDD with Vista

So the gpu is from a computer that was in a fire, but I tested it before putting it in, and it worked fine, and yesterday we watched a few movies. So my wife turned it off via shut down from start menu, so everything is right, and ok right? wrong

When I turn on the computer, it normally beeps at me to say hi, then starts up. Well today I crank it up to watch some TV, and didn't think anything of it, but no beep, and no lights on the keyboard (which now doesn't work in any machine), and no signal is getting to the monitor (TV). So I go to check it out, everything is on, disc drives all open and close, fans are running, light on the mobo is on, HDD fires up, just no beep, no POST, and no boot up. I tried exchanging the CMOS battery, removing the jumper, checking all connections.

I only have a spare i7 cpu, and mobo(the ones from the fire) and DDR3 RAM so I can't really swap anything out to try different things, and the i7 mobo only uses SATA drives, no IDE so I can't really try hooking it all up anyway as the only SATA drive I have is in my main machine.

Any ideas what it could be?

i'd guess that your motherboard is dead.

yeah probably some traces in the motherboard that don't prevent powering on but prevent anything else from happening (POST). This just happened to one of my rigs, working just fine, turn it off, and next time go to turn it on and nothing.

just for the heck of it, try removing half the ram (if its 4 sticks) and see if that does anything.

A bad GTX260 actually once prevented my P6T deluxe from POSTing AT ALL. No beeps. Thought it was the P6T but when I got my second GTX 260 for SLI, I popped the old one out and put the new one in and it posted.

Winner!!!

I removed my HD4850 and swapped my old 7800GT in and it fired right up. It's just weird because it was working fine the night before, but the card was probably due to die as it came from a computer that had been in a fire.

I wound up rebuilding the i7 machine with the psu from the 3500+ box, and moved the 7800GT over to it. The 7800GT isn't tough enough for 1080p video, but the i7 chews it up and spits it out, and doesn't ask for help from the gpu.
