Help!! My computers gone dead.

[coslov]

Hi,
Well, I reformated my computer the other day then re installed windows. Then i turned my computer on and it was all looking great and like a nice clean computer should look.
I then went and installed my belkin network card drivers. when it had installed these drivers it asked me to restart my computer as they always do.
I then clicked on restart now. It then powered down to a black screen when it was meant to start loading windows again. So i turned the pc off with the power button and turned it back on again. All i get now every time i turn it on is the "no signal" warning on the monitor.

It will never go any further than this. I have tried changing the graphics card, the ram and the belkin network card. Yet it still wont do anything.
When i press the power button the computer base unit sounds and looks like it always has done but it just wont show anything on the screen. I have also tried it with another monitor without having any sucess.

Does anyone have any idea what this is or how to fix it? The only thing i can think of is that its something to do with the motherboard or cpu.

Any help would be great.

Thanks

Try resetting the CMOS for one, mine did the same a couple of weeks ago and the CMOS jumper brought it back to life.

Do the fans spin and the hard drive spin up? Could you try another power supply?
