"Computer was working fine until i decided to clean dust out of it"

How did you go about cleaning it? One of the worse things you can do is use a vacuum because a static charge can build up within the hose & wreak havoc with the electrical components.

"I removed cpu and damaged pins beyond repair"

Bent pins generally aren't a problem, if you're careful, they can be straigtened & the CPU reused. I'm guessing you snapped some of them off? How the heck did you manage that?

"I bought another cpu and fitted it correctly"

Did you buy the exact same CPU? If not, are you sure the replacement is compatible with your motherboard? When you reinstalled the heatsink/fan, did you thoroughly clean the bottom of the heatsink & apply a small dab of thermal compound to the top of the CPU?

"now red & green light stay on with no beep sound"

Cases have different color lights so red or green means nothing. The fact that there's no beep is not a good sign though. The problem is most likely with the CPU or the motherboard.

I straightened the pins and tried it again ,still did not work. Thats when i got another one and put it in with a dab of thermal compound. Tried a few things ,cpu does heat up after a few seconds.There was a small battery on the board i removed for a few seconds and put back ,does this reset motherboard to factory specs ? Or should i just throw it as far as i can.?

i think we need the answer re was the cpu the same. it was a pentium 4 2.4ghz? is the replacement a pentium 4 2.4ghz ? is the spec the same , if your old one was 533mhz fsb (it will say 533 on it)and you put something different in like a 800mhz fsb cpu then it might cause a problem. but it could be loads of things, eg. motherboard gone bad or you have dislodged a ram stick whilst. removing battery can clear/reset the bios settings but sometimes battery needs to left out for a while. An instant way of doing it is to use the CMOS CLEAR jumper on the motherboard which is often near the battery
