Do you hear any beeps when it does?

If there isn't one and you haven't got one (or something similar that will work), I suggest that you get one of these speakers and connect it to the motherboard and hopefully when it fails to POST you will get a beep error code to tell you what's wrong. Search online for ''PC system speaker'' to find suppliers that suit you best.

On p.61 there's a beep error code chart that details what each of the beep codes mean.
