I just recently put together my computer and tried to install ubuntu after i already had xp installed. after 2 failed ubuntu installations, i rebooted my computer and changed my cpu clock speed to 3600 MHz w/o changing any other voltage. i saved the changes and rebooted and the monitor couldnt display anything (aka black screen) and then i noticed one D1601 led on each graphics card light up. Can anyone help?

  1. Something like this happened to me . I just removed the CMOS Battery and then replaced it back. Remove for like 5-10 seconds until the BIOS automatically resets. Its because of the overclock. Or use the CMOS jumpers to reset it.

    If not try the monitor on the onboard video port.

    Reset the BIOS and try for a less agressive overclock.
