Computer powers up but won't boot.

I was searching the web and my computer froze. When i tried to restart it wont boot. It's not going to the bios screen and there is no power to the PSU keyboard. Everything else seems to be powered fine. Any help anyone?

 

So do you have any lights....fan spinning etc.........

 

yes there is. everything is working apart from there is no power to the psu keyboard. Also, the fans stay on at full speed. Normally when i reboot the computer the fans start at full speed, then they slow down after 5 seconds when it boots up.

Ive got a mesh tower powered by asus. its a quad core 2.4ghz. Im running 64bit windows 7 ultimate.

 

Is this a USB keyboard....and can you try another keyboard

 

You mean the computer is booting all OK?
Try a differnet Keyboard...

 

thanks for the replies. I've just tried another keyboard using the PSU input. I'm going to go to the shop soon to buy a USB keyboard.

The computer isnt booting. All the fan, lights and mouse is powered, but there is nothing on the screen and keyboard isnt powered. There is no beeps either.

 

Check all the fans are working heat sink fan and Power Supply fan....have you tried another Keyboard yet?
