Wonder if anyone has seen anything like this. When I start up my machine, I am getting this very strange shaking quality to the screen image...the apple icon looks like it's on the back of a very beat up truck on a really bad road. It's shaking like crazy...in addition, the screen has a lot of gray lines that recall a really bad old b/w television. sometimes the desktop will finally load normally, and other times i get a full screen of a weird cross hatch pattern and I have to shut down and start over...
any thoughts on this would be much appreciated,
richard

One of the old eMacs in one of the labs at my college does the same thing. Because they are eMacs I guess they don't care about getting it fixed. Wish they would and then I could probably give you help. But it is something wrong with the monitor...can't really pinpoint the problem though.

You may want to check the video card.

Run the hardware test included on the install disks.

I try to Command+Shift+/ when I can.
