Hi,

Here’s an image taken from page C-11 of the service reference guide for your desktop, which shows what a 9 beep error code can mean.

It could be a faulty PSU so check the various voltages being supplied by the PSU to the motherboard to make sure that they are all OK.

If they are OK then it may be a CPU fault or a motherboard fault.
