The computer stopped working one morning so I replaced the PSU. I bought a 600w Thermaltake. Got that installed no problem.

After turning it on, the CPU, case, PSU, and GPU fans all spin but we get no display output at all. The fans seem to be louder than usual, but that may be my imagination...another peculiar thing is that the red light on the top of the case (around the power button) does not light up red as it usually does and the green light doesn't light up either.

I've since taken the GPU out just for testing. I also removed all memory modules and put them in one by one but it changed nothing. There is no POST beeps either. I'm kinda stumped..have no clue what it could be. Thanks for taking your time to help me Tom's Hardware!

Plug everything back, except for GPU, and connect your monitor to integrated graphic. Power your PC. Can you hear is HDD spinning?? Is there any sign of picture. If no, then probably your MOBO is gone.

Unplug your HDD, CD/DVD, take out memory, GPU, all cards...
Check your capacitors, they should be flat. If there is "bubbled" they need to be replaced. Try to start PC with another GPU, but nothing else attached except memory. We need to get to BIOS screen, from there is little bit easier.

I have done all of that already. I don't have another GPU at my disposal however the integrated graphics was always sufficient before I purchased the GPU. Right after I hit the power button the fans just start going but nothing else seems to be happening. Could it be the motherboard or no? What do you thing it would be? I have everything plugged in that I can tell. I'm so irritated I need to get back on Skyrim! Lmao :)
