Have you got the speaker inside the computer connected? Are there any beeps, have you checked the connections for the graphics card and monitor?

Try removing all plug in modules (e.g graphics card, other PCI cards, memory) and see if it boots. I had a system where the graphics card packed in and must have been pulling down a power line and this stopped the pc booting.

It could be worthwhile re-setting the bios to the default settings, this is commonly done by moving a jumper on the motherboard.

Before doing this obviously make sure all power is off, and observe anti static precautions.

Try doing this and then booting up to see if all OK, you may then have to adjust various bios settings such as fsb etc.

Please if you are unsure about any of this then tell us before going any further !
