Hi,

Last night I left my PC on as I was downloading from the internet. When I came down to it this morning it had turned off, so I went to turn it back and the two lights at the front came on, the fan came on but nothing else happened with the screen saying no signal.

The computer had a new power pack, and graphics card not so long ago, so I am thinking it either the motherboard or processor? Is there anyway of working out which without buying both when only one is needed?

Thanks

I'd replace the PSU first

if you still have the old graphics card try putting that back in first !
can you hear any thing inside the machine such as the hard drive working etc.
check all the connections on the mother board best way is to remove the connectors blow them over then return them from whence they came !

I had a similar problem recently all I had to do was remove the prosessor and refit then everything worked fine.
Acording to a friend it clears a corruption

Thanks for all the help and ideas I have tried everything you have suggested expect for the PSU which I will get tomorrow, but none of them worked

Once again Thank you

Phil M

Just tried a new PSU and still nothing

Unplug everything from it -- mouse, keyboard, USB stuff, any pci cards and try it.

Thanks for all the help, it was after all the motherboard
