Hey guys same issues for me. I have an older r10K, 195, 128mb, SI gfx, I think. Anyways, bought it of of E-bay from a guy I know pretty well. Worked fine before shipping, but when I got it, I pressed the power switch, and it turned on or at least both fans did. The only way I can start it now is by plugging in the Pw cord, and vise versa to turn it off. I did carefully reset the PW supply several times, removed the battery, pulled it completly apart and resetted all boards, It was reeally dirty, So I dissasebled it and used compress air. When it is plugged in it will turn on, I really can't hear the HD over the fans, there is no red light on the front. If a PW were bad, to the point of powering the fans, could that be it. The switvhes on front don't do anything except after the first time. My monitor arived the next day and it came in peices, it looked like UPS entered it in a rugby turnament. I'm pissed. I have a nec SOG monitor that works on my o2, which is currently using a 1600sw, The seller did say that once and awhile he would have to reset the PW supply.
I'll try the memmory swap, and see if I can drive to reputable.com after work and hook it up to a display.'
Any ohter suggestions, oh and the connectors look fine.
