Graphics card problem

[spaztic24]

H have a 2002 hp 512c desktop running winxp.
256 memory
I went to shut down my computer and it wouldn't shut down.
So unplugged it. The screen said something about not reading a graphics card.
Tried turning it back on and nothing.
There is no graphics card in there. It's hooked up directly to the motherboard.
Is my computer trashed now?

Tried turning it back on and nothing

Remove the power cord from the back
Hold in the computer's ON button for 30seconds (dispersing all internal voltage)
Let go of the button
Plug the power cord back in (push it in hard)
Turn on

If that doesn't work, please let me know if there are any power lights whatsoever?
If not, it can be the PowerSupply has gone.

ok, plugged it back in the lights on my cd rom drive and my dvd drive lite up then nothing. My monitor was black.

I still think Power Supply

But at this stage you will need to open the case and remove all dust, reseat all cables and plugs, plus reseat all PCI devices.
(Computer HardWare experience required plus electrostatic precautions)

Here's a good BenchTest guide

Can I just install a new graphics card in one of the empty slots.
