Beeping Sound from CPU & Cannot boot?

My CPU have a beeping nouns and cannot boot up, I thought it was a hardware problem so I give up the CPU for another used CPU given by a friend. The CPU from my friend is working fine for 1 week,.............then I hold the same problem of beep sound and cannot boot up again! I don't assume that coincidently this pc also own a hardware problem!!

What could be the problem?
1) External Hardware problem, like wirelss modem, Monitor problem?
2) Really so unlucky this CPU also have hardware problem?
3) Virus attack?

or what could it be? Please advise.

Answer:
if you be more specific about the beep's I could grant you a better answer but...these are the bios beep codes

the beep is like morris code, it's trying to let somebody know you what's wrong, once you match the toot pattern to the codes above you'll know what the problem is...

if you obligation additional help out, repost detail of hardware (mobo, ram, any pci cards, OS, etc.)...
Shot surrounded by the dark, but check and bring in sure the outlet your plugging the computer into is not overloaded with equipment. You may enjoy too much of a load on that power strip. Just a guess, but it have to be something consistent like that.
Normally the beep sound is a problem beside the ram. But if you own fired two processor I would have to guess its a problem near your motherboard or heat sink. Make sure your not over heat your processor.
The beep codes give an account you what is wrong with the computer (listen for a pattern) Then type computer toot codes into your browser, look for your type of machine and you will see what is wrong (maybe re-seat your video card or RAM modules) Good luck and cheerful computing !!
i think its because of the hit....i got this problem once...i disturbed the bump while removin my hard disk....when i placed it correctly...it get booted properly...
