Depending on your boards type beep codes, one short, then 2 short beeps normally indicates a check sum error. This is when your board does'nt like the speed/size or make of your memory. Removing the battery probably hasn't cleared your cmos,look for JBAT1 terminal on your motherboard and place the jumper over pins 2-3 for a few seconds and then back to 1-2. Try to boot again with your original memory. With some boards you have to have equal amounts of memory in the slots (e.g 2 x 256mb or 2 x 128mb) and some memory may not be compatible with your board. If you get up and running go to this site to check memory upgrade options.http://www.crucial.com/uk/store/listmfgr.asp?cat=RAM

Try removing everything attached to it. The only thing should be the cpu and cpu fan. Turn it on. If it is the same, then it is your motherboard. If you do get the beeping, then start installing things one by one starting with the memory.

If your power supply is not plugged into a surge protector, you may be having issues with your line causing your power supply to fail. Do you get any beeps? The bios typically will beep to give you an indication of what is going on?

I would say it's the graphics card that's failed. You might get the same beeps for faulty card as removed card....
Take it to a shop where they can test a compatible card, before they sell you one or install one for you.

much trial-and-error, I finally figured out the solution for this
common issue with certain HP Pavillion models. It turns out to be a
design flaw with the front-panel memory card
reader. Somehow the card reader's firmware gets scrambled, and it
prevents the computer from booting. You can test this on your machine
by temporarily disconnecting the card reader cable at the motherboard header. Voila - I'll bet you $1 that your computer will now boot!
The solution is buried deep inside this HP tech support document. The card reader firmware needs to be reset.
Here\'s how to fix it once and for all:
1) With the computer power unplugged (duh), open up the case & disconnect the card reader cable at the card reader itself - NOT the end that connects to the motherboard header. Make sure the cable end is not touching any metal components before proceeding to step 2 (another duh).
2) With the cable still disconnected, fire up the computer. The tech support doc says to let it boot into Windows and stay there for about 5 minutes.
3) Shut the computer down and reconnect the cable to the card reader.
4) Turn your computer back on - your memory card reader will work and, most importantly, the computer will no longer hang at POST!
I suspect that when you fire up the computer without the cable connected, the card reader is designed to reset its firmware by grounding out through the case - sort of like a CMOS Reset jumper on a motherboard.
I hope this solution is helpful to others.
