I have an optiplex GX260. Started running slowly, even to come off screensaver, then just died. Now, it shows a green power light, the MOBO shows an orange light, the power supply fan is running, the HD spins....but it will not boot or even give any BIOS beeps. The monitor says no signal. I have reset the MOBO by unplugging and letting it sit...nothing. What could be causing this?

- Just wanted to clarify, the light on the MOBO is orange, the front panel light (power button) shows green. I'm not sure what you mean by the monitor, but I assume not the screen. Before I buy a power supply (which I do agree sounds like the problem) I want to make sure on the lights.Nov 04, 2007
- Tried a new power supply, nothing. It will not boot from a CD, HD, or floppy, and the diagnostic lights on the back show a/b green, c/d orange which does not equal anything in the manuals.Nov 04, 2007
- It doesn't display anything...it can't boot. The screen continues to display no signal. It doesn't even get to a BIOS-beep. Turn it on, power light goes green. Checks the cd, checks the floppy, one short flash for the HD and it stops there. Power light stays green. Does the same if I put in a bootable CD or bootable floppy.Nov 12, 2007
- OK, FIXED. Had to go component by component to find the issue. Brought it down to nothing but the MOBO, removed the battery to reset the CMOS, that checked ok (BIOS beep for no-memory). Added the RAM, that checked ok....added items up until the video card. Then, died. Running it off the onboard video atm. It is running slow for video (sharing the onboard 256MB RAM), but it is running. ab green, cd orange indicates "system resource conflict".
