Computer will not start

[spadel]

Hi, my computer will not start when I press the power button, not even the fans go on. I changed the alimentation but this has not solved my problem.

The led on the motherboard is on (green led), so electricity is is going through.

The problem started following a freeze on stand-by, I was not able to shut it down by maintining the power button. I finally hat to cut the power using the on/off button at the back. Ever since, the machine doesn't start...

I occasionally had a problem in the past with a "overclocking failure" message when starting the machine. Strange, because I have never tried to overclock.


Thank you for your help.

Sounds like a possible RAM failure to me. I'd go through this checklist and post your results back after you're done.

you could also try resetting the bios using the jumper's or remove the power cable and the motherboard battery for atleast 5 mins (10 - 15 mins maybe) and then replace the battery and plug her back in. This should totally reset the bios.
