Journeyman III

No screen display

I built the computer below a few months ago and it has been working fine (except for a screen freeze every now and then). A few days ago the screen suddenly went black. I cannot see anything, including boot-up screen or BIOS. I have tried a different monitor, HD, cables, I have tried to boot from the CD/DVD and nothing happens. All the fans are running and HD is spinning, just can't get a signal to the monitor.

leeu, your power supply seems a little weak, but I doubt that is your problem.  Can you borrow a video card to try?  Are you running the latest BIOS version for your MB?  Please follow the instructions in your manual and do a Clear CMOS and see if that helps.  Please get a speaker for you MB, so you can hear the beep codes at boot and post them.


Thanks and enjoy, John.
