PC wont boot.

Rev

Hi,

Hope someone can help, I have friends PC. He asked me to take a look as it wouldn't come on. I assumed if it wasn't turning on it would be a PSU problem. But having had a look it does switch on. With it actually switching on, but no display getting to the monitor I thought it might have been a problem with the on-board graphics so I installed my spare graphics card, still no luck. Tried a different monitor, no joy.

So it powers up, but that's about it, no post beeps, no keyboard light, nothing,

Anyone have any idea what it could be?

Thanks.

dead motherboard if everthing else works cd/dvdroms,harddrives power up ,fans come.

I was really hoping nobody would say that lol.

Fans, dvd drive and everything still come on, just no signs of life at all besides that.

Agree with above try and see if you can access the motherboard bios usually as the computer is starting you press dependant on make the escape key or one of the function keys.
How old is the computer.

the delet key is a good place to start with trying to get in the bios and F2,F10

I've already tried accessing the bios, no joy.

The PC is around 15 months old.

:idea: worth a try re the bios which makes it look like its terminal as banger9365 indicated.
With the power off take the cover off what's it like inside is it full of dust could it have overheated?, while inside remove and then reattach all connections on the board you have nothing to loose.Remember and earth yourself before starting
I remember opening up a computer and you would have thought it was being used down a coal mine. It was exhaust fumes and dirt the pc was located on the office floor in a garage externally it was clean, inside was another matter.

It might be worth trying to clear the CMOS, then seeing if you can get into the BIOS. Its also doing what malmute says, a clean up and reconnection.

Rev

PC has been cleaned regularly so was pretty dust free. Reattached all the connections, still no joy. Oh well, guess I'll have to pass on the bad news.

Thanks for the replies.

Did you try Zagu's suggestion re the clearing cmos, methods to carry this out are available on google use clear cmos as your search.

banger9365

yes i would give the cmos restting a go and if that do not work ,
if you have a spar psu you can try that to in case one off the rails has gone bad or lose,put i think thats looking for a miracle
because new psu have more that one output eg mine has three 12v,5volt and three 3 volt outputs

by the way what make is it ??
