Question about Dell System Board for Optiplex GX 150, PIII DELLGX150SB-06 Motherboard
Our computer screen just went black. Can't get windows or anything to start on the monitor. I hear the computer buzzing but it won't do anything. I tried rebooting, tried F8, looked at all power cords etc. Nothing. Could it be a virus? Hard drive? Motherboard????
It helps if we know what kind of computer you have, and the model. Go to the manufacturer's support site online. (HP.com, or Dell.com, etc) and search product support for your model # and then search for blinking lights or error lights + black screen or search startup problem and see if you can find the page that explains what the light codes for your system indicate.
Your power supply may have failed. See also link to startup troubleshooting here.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
