Hello group. I've got a Sawtooth (450 MHz) with some issues surrounding the display and most likely the video card. The machine has been used as a server for a long time and recently I wanted to put it in production. I moved the machine to a new location and did a fresh installation of Tiger on it. After being unimpressed with video performance from the original ATI Range Pro 128 (the default/original graphics card), I bought an ATI Radeon 7500 and popped it in. It's currently connected to my DVI monitor (as opposed to a VGA connection and it used to be to a different monitor). The issue I'm now having is these moments where the the display will black out for a few seconds and return to normal, almost like it lost a connection for a second. It seems to happen most often when I'm moving around windows or scrolling swiftly through webpages, etc. I know it's not the monitor or cable as I had been using it on another machine just fine. I never had this trouble with the ATI range either. Any ideas as to what is going on (already repaired disk permissions, reset PRAM, reset PMU, and booted into open firmware and entered the command "reset- all")?
I don't know what's going on but I have a Radeon, either 7000 or 7500 in my QuickSilver and when I had it connected via DVI it would every few minutes throw black streaks across the screen. I don't think it went completely black but it may have, it's been a while. The monitor is a 1600x1200 and when I dropped the resolution it didn't do it. I never tested it any further, I just switched over to VGA which hasn't had any such problem. It didn't seemed to be tied to any computer activity, it was just periodic.
