haven't read all the replies, but imho the processor is screwed, I can't aimagine a PC not booting for a bad videocard, but then again I'm not a hardware specialist.
look up the beeping code though, it'll explain a lot
Yes give it to me such a useless pc.
No serious, It's most likely you video card is not attached well to your bus on the motherboard. Those beebs tell you that the PC can not get to your monitor. the worst is that your videocard is busted, but I dought that. Is the cable of your screen attached properly I know silly but it happend to me <img src="/ubbthreads/images/graemlins/shame.gif" alt="" />
