Turned my desk top on yesterday. It booted into windows fine but then went blank, nothing on the screen. Used keyboard to try turning it off (windows button/up button/return/move right/return.) Checked this with laptop this morning - fine.
The hard drive wouldn't turn off, so I tried restart button - nothing, then I tried on/off button held in for several seconds - nothing. Had to turn it off by switching the power off at the socket.
Now it won't turn on. It turns a light on & off on the cd drive then the red & green on the hard drive flash on & off, nothing on the dvd drive.
I've tried unplugging the cd & dvd drives separately & together - nothing. I have 2 hard drives for this pc, in cradles, get the same result with the other drive in.
i once had a similar problem which i solved by resetting my bios with the jumper on the mother board u could try this before buying a new power supply the instructions for this u will find in the mbord manual
