Chosen Solution
my pc is not starting just constantly beeping for nine times with red light flash again & again. I can’t recognize what problem it has, I watched some videos to fix it on youtube but I find out that my pc is beeping for 9 times all of the videos that I watched on youtube have the solution for 5 beeps none have 9 beep problem solution.
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.
