Hello. I've got a HP Compaq dc7700 Small Form Factor PC that have a problem. When I'm pressing on the power on button, the computer try start up but immediatly stop and instead start to beep. It have 9 beeps. One second beeps. I've tried seached on google but without success. I have reseated the processor and disconnected everything from the system board as it says i sould in the hp support, without success.

Try reseating the RAM and any other cards (video card, sound card, etc). If you have more than one stick of RAM, try turning the machine on with just one stick inserted. If it still fails with that stick, take it out and try another one.
