If anyone has a working T3120, I would appreciate your help. My onboard video is dead and I need someone to document the exact keystrokes needed to disable the onboard video in the CMOS so that an add-in PCI Express card will work. I'll have to make the CMOS change blind, so I need the exact keystrokes. These machines are crap, so why not replace it? It's my Dad's and it works fine for him. Why do I think the OBV is bad? It seems to start up fine, making all the expected signs. The capslock light toggles as expected. It shuts itself down if I enter the keystrokes to shut down a WinXP machine (ctrl-alt-delete, ctrl-alt-delete, alt-s, enter). These things seem to indicate that it's functioning okay, except for video. Could it be the monitor? I've tried two different monitors, both work fine when connected to other machines but have no signal when connected to the T3120. What else have I tried? I installed a PCI-Express video card, but there's no picture. I installed an old PCI video card. Got one long beep and two short beeps, but no picture. Any other suggestions appreciated.
