ok, now i truly don't have any idea what is going on...check this out:
got the replacement pc from gateway yesterday. it came with a crappy video card (5200 analog only) so i swapped the video card out with the 9600 from the other machine (gw said that was ok even though i was sending the other machine back). set it up, powered it up and i'm in business. spent some time getting the peripherals and other stuff going, involved a few restarts--no problem. shut the machine down feeling pretty good about the situation. come back to it a couple hours later, boot it up and i have the exact same, totally garbled video i had on the old machine!!
so i thought, aha!! i know the problem, it must be the 9600 video card from the other pc (even though it's been tested at least 3 times). so i take my gf4 ti4200 out of storage and pop it in there thinking this should work, but no it doesn't--same garbled video. i also tried unhooking the bluetooth keyboard/mouse that i had and even moved the pc to another room in case there was some interference or power problem that i was not aware of...ok, i admit to desperation at this point!!
i took the new pc and the old pc into another room and tried both with both the 9600 as well as the gf4 video cards--nothing doing. so i think, what is it that these have in common--dvi on the card, dvi on the monitor (dvi connection only on the monitor i have). again i think, let's see if analog connection will work. so i put the 5200 back in the new pc (analog only) and got an old crt monitor out of my garage, booted everything up and low and behold it works!!!
so now i have a new pc that seems to work (but given the problems we'll see if it shows the same problem of booting a few times and then dying), but only running analog video with an analog monitor. that doesn't seem to be a great solution to me.
any ideas--i'm totally stumped--somehow the interaction of dvi card and monitor won't work, but now we're talking about 2 video cards and two pc's....same monitor though (although gw replaced the monitor already a while back in the process)....
thanks!
