HP desktop

We have a HP white desktop (unknown model) and we have tried everything to get it up and running, everytime we plug it in, itll beep. 3 long, 4 short, for a cycle of 5 times. Then itll pop up a error screen, it says the ac adapter that came with the desktop is unsupported, and that there is a keyboard issue. We really need this computer for the clinic. please help a girl out so we dont have to bug the owners for a new desktop.

Hi:

 

See the link below for how to troubleshoot the beep code sequence your PC is emitting:

There seems to be a problem of some kind with the PC's power system, no doubt the power supply is no good or of insufficient wattage.

 

Without knowing the full model number or product number of your PC, it is not possible to let you know what the part number of the power supply that your computer uses is.
