PC will not post

A few days ago, my PC kept giving me the BSOD, and eventually, it would randomly shut down. I figured out that it was the PSU, and I changed it as soon as I could. Then it started to say windows files were corrupt, so I tried doing a repair install of windows, but it kept locking up when it got to kernel debugger DLL. I looked up why this would be happening, and I read something that said to reseat the ram, and clear the CMOS. I did as I was told.
After I did that, the PC got stuck on the bios loading screen. After about an hour or so of waiting for it to load, I shut it down and tried to start it up again. Now all I get is a screen that says No video input in a little blue square on the screen.

things I have done since then:

• tried several video cards
• added and removed RAM
• tried using a different monitor
• clearing the CMOS again (by removing the battery and again by switching the jumper)

it's not posting or making any effort to boot, the only thing that seems to be working right now is the new PSU

 

Remove your graphics card as well if you have onboard display.

Maybe your bios got damaged somehow, update your bios by flashing it with a new version.

Wishing you luck.

 

so everything including the HDD, DVD drive, and RAM?


that's all that that is in it besides the Video card and CPU

 

ok so, still nothing... it's the same as before, no beeps or anything that can give me a clue as to what is wrong... I'm starting to fear that the mobo has died, which means I have lost my gaming rig until I have enough money to buy a new one

 

How bout installing another OS in another partition?

 

Replace the fan?

It did work well before, no?
Maybe your fan has lost his last life.

 

Oh ok.
I thought without fan it could not boot because something was too heat...

 

Nope, no beeps at all... but the LED's do come on

There are 7 fans inside this PC, heat wouldn't be an issue

 

um....the white thingy under the CPU? put some thermal paste or something

 

I am out of it... mabe a loose wire or mabe something melted...or a shortcircuit don't you think?

 

well, damn....

I'm going to try to look if there are any short circuits or blown capacitors on the motherboard

 

this may sound stupid, but use your smell...sniff out the motherboard XD ..see if you sense anything burnt like
