O/T"Puter Problem"

Sorry for the Off topic - bvut without the puter I can only get on here by borrowing someone elses!

Mine has started acting up.

It's only a couple years old and a top of the wazza dual core processor etc etc.

It suddently switched the flat screen off and just makes a 3 beep sound when you turn it on - 0one long beep followed bye 2 short beeps.

I figured that coz the monotors not working maybe it is the graphics card, opened the ox and sorta wiggled the graphics card in its motyherboard slot a little.

Itstarted right up and worked Ok for about 3 hours whence i turned it off.

Next day when I turn it on the same problem, no screen and 3 beeps One long followed by 2 short.

Wiggled the graphics card again - no help this time.

Tried pluging the graphicscard into a spare slot on the mother board, still the same problem.

Does this mean the graphics card is shot?

It's a pretty expensive top of the line ATI Radeon X Sapphire 1600 pro graphics card.

Not really sure what to try next - the fact it wouldn;t go then it went again now it wont go makes me think it might just be a dry joint or something?

Just curious if the beeps combination means anything and how I would know if it is a motherboard or graphics card fault?

Many thanks in advance.

Cheers
