Problem Motherboard Installation

Specs: Windows XP, P4 Prescott 2.8 MHz
Just installed used mobo -- identical to one it replaced. After optical drive not recognized for a a few months by old mobo (had tried several drives, would not recognize any), computer suddenly shut itself down. When restarted, would not boot past agp driver. Replaced graphics card with one that I know works -- same result. Consensus, old mobo (about 5-6 yrs old) had died. Other than optical drive, everything seemed to work before crash.

Computer powers up, hard drives and all fans whirr (including graphics card) -- but no video, mouse or keyboard. No sound. What else is or isn't working not obvious under circumstances. Connections "seem" correct. CPU seated properly.

Reseated CPU. Tried reseating at least some of the RAM modules.

Hard drives work fine when accessed as data drives by other computer. At least by visual inspection, mobo seems complete. Seems even if memory modules not all in right, should still get something.

What can I do -- short of taking to technician to test mobo with instruments?

You should have tested the mobo outside the case. At this point, disconnect all drives and try booting up with just 1 stick of RAM.

No difference with no HD and just one RAM stick. No video and keyboard lights don't light. The only thing I discovered -- but before this test -- is that the mouse lights up when connected to the multi-pin connector (forget the name) -- but not when connected via USB...still no keyboard or sound...

What kind of test could I do outside the case with the mobo -- if I uninstall in from the chassis -- without electronic testing gear?

You can boot up while it's outside the case and see if the results are any different. Disconnect the mouse as well. It's possible that the mobo is touching the case somewhere.

Thanx for the suggestion. No difference with the board outside the chassis and not touching anything.
