PC doesn't show anything on screen

when i turn on my pc it doesn't show anything on screen like manufacturer logo, bios info, system infos

my monitor goes like stand by

i check my monitor its not defective

i didnt overclocked it and sured it is properly cooled (39-45 C)

my cpu spec:
Pentium 4 1.8 ghz
512 mb DDR ram

i think the processor is the problem cause i only turn it on for less that 30 secs and the processors heatsink w/fan goes really hot, am i right???

Excesive heat could cause these problems. Have you cleaned out dust, etc with compressed air?

When you say you haven't got a video card, do you mean you haven't got an add-in card and you are using onboard video?

Technically, you do have a Video Card, its just integrated into your motherboard. The troubleshooting guide linked to above still applies.

But why is this thread here when the OP has Windows XP installed. I thought this was a Windows 7 Forum

That would be my fault, John, since I was the one who originally responded to the OP. I must have missed the XP Pro in his System Specs.
