Compaq Deskpro - video problem?

Just started on a Compaq Deskpro, couldn't find exact model/series written anywhere. When I turn it on, it sounds like it starts just fine, no beeps or anything, also no video, monitor light just blinks blinks once every 3seconds, meaning no video signal. I pull the agp card and connect to onboard graphics, same thing happens. I replaced processor, same thing. Before connecting to onboard i changed agp card with 4 others of same model(ATI Rage 128 Ultra), same thing. I've gone thru putting single sticks of RAM in it left and right, thru about 5 sticks of ram ranging from 128mb - 512mb.

Numbers/Names on case and boards:

sticker on mobo says:
CPQ Assy. No:213855-101
CPQ Spare No:203966-001

small silver tag, outside of case:
EXSM/815 P866 M1 BASE US

COA: Win 2k Pro 1-2 CPU

anymore questions, just ask.

    everything is getting correct voltage via plugs, inserted a max-size stick in(PC133/512mb), still no-go....bad mobo maybe? or bad memory slots?

    screen flickered for a sec, but went off and hasn't shown again, checked monitor against another computer, monitor is fine.
