My first post on Daniweb - I just discovered this site from Google! Looks awesome!
I have a HP Vectra VL420 DT that I bought a month or so ago. The PC is out of warranty.
When I inititally tested it, it worked fine. Now when I try and turn it on it makes a warble sound followed by 2 distinct beeps, which I am told by HP support, means that the PSU is in protected mode - it could mean my motherboard or PSU is faulty.
Now here's the scary thing - I looked up some threads on the HP support site and found some other people who had had the same problem as me. And one guy said he had bought a new PSU and the PC worked, then the 2 beeps came back again!
Has anyone else out there had this problem or have a solution?
