when i turn the power on the fans spin up then it beeps from inside the case. Nothing happens at all just a few beeps then it just sits there with the fans running, on the mother board there is an amber LED which is on until i unplug the power supply and when i try and start up the computer another green LED comes on. Thats it just the fans, those LED's and the beeps, oh and the cd & dvd trays will open and close but nothing else.

Thank you in advance

How old is the machine?
The yellow LED is just a indicator of power to the system.
How many beeps do you get?

Thankyou the memory was the problem, I unseated it and put them back in a different order alls good now.

Good news. Do please mark this thread as SOLVED.
