MOBO and GPU issue

[fallenapples]

A while ago I wanted to add a GPU to this HP desktop HP Pavilion Slimline s3220n Desktop PC Product Specifications | HP® Support, I changed the stock 160W PSU to a 250W and added this GPU Buy the EVGA GeForce 8400 GS 1GB DDR3 PCIe, HDMI/DVI & LP at TigerDirect.ca. I set up everything and it worked flawlessly. Then I shut it off and it never turned on again. Nothing would work, until I tried it recently, the CPU fan spins, as does the GPUs, but no picture. And no beeps. I reset the jumper and switched the CMOS battery, changed the RAM and still nothing What could the problem be?

Do you get a picture if you try to turn it on *without* the GPU installed?

No. The on board GPU was giving me problems way before. I would have to wiggle the port to get a picture. That's why I chose to try a GPU. I thought I might have short circuited the MOBO.

Is this the same motherboard as before? I'm getting a bit confused now

If so, the board could just be dead.

It is the same motherboard. I'm guessing there's no revival?

Only thing you can try is onboard VGA if it still worked at all. If it boots then gotta keep troubleshooting to try and make it all come up together.

But the on board VGA was toast from the beginning. I had to keep wiggling it; then it just stop working altogether.
