Pretty much said it all right there, But still the symptoms:

Once I press the power button, the PC switches on, light's up and what not. Monitor fails to turn on (however, it usually takes a few seconds anyway) After a moment, the PC just starts bleeping like some crazy bleep machine on speed.

I figured maybe something was loos inside due to washing machine going off and vibrating everything, but I opened it up today, pushed everything down a little to make sure it was in place correctly, moved aside a few wires to make sure they weren't touching what they weren't supposed to be touching, and then double checked the connections.

When I plugged everything back in, the computer wouldn't even power up, so I removed the power supply, retried, and this time it booted to the bleeping noises. A few angry whacks later, it boots up just fine, as you can see.

It's getting very annoying and I'm wondering if the techy types out there know anything I can try for free before it comes to replacing parts, because I really can't afford it.

Thanks.

EDIT: It seems to be a video problem, i found this over at pcstats:

One Long Beep, Three Short Beeps Video Problem

yea, beep codes when you start up mean you have a piece of hardware failing. Exactly what your beep codes mean depends on the BIOS on your motherboard. Be glad you're getting beep codes. I've never gotten any. Any time my crap fails, I have to figure it out the hard way.

Well i need a new computer anyway. But i need money. I've signed up for one of them's free iPod things on the net, so I can get the iPod and sell it to a mate at work.

except for the import taxes your wonderful government levies against everything coming into the country.

Exactly Satis. Watch out for the nasty nasty customs charges. You may end up paying your gains entirely in tax. Think about UK power compatibility too.

I love it that the GBP is pwning the USD atm!

I assume GBP == the pound or whatever. Don't know the stupid symbol. But anyway....

hasn't it always owned the $? I don't remember the $ ever being worth more than the L.

Yeah as far as i know, pound has always been high in value. Which isn't always a very good thing. But my background isn't too economical so i don't know much about it.

GBP = Great Britain Pound i assume.

If your currency is expensive compared to other currencies, then buying things from those other coutries is cheap, wich is good, but competing with companies from coutries with a low-valued currency is harder, because making stuff is more expensive. Just look at British Steel.
