Lost Suse 9.0 at boot!

I turned off my computer, shouldn't have done that I guess. When I turned it on Suse 9.0 with all upgrades went through the text part of the boot, when It got to the graphics part I got part of a screen full of vertical closely spaced colored lines. When the boot finished, (at least the HD light quit flickering) I had a screen full of these multicolored lines and that was it. Stock KDE and stock kernel. Tried the "repair" off cd1, it asked for repair login, apparently that's not the same as "regular" login as it wouldn't accept my input. Any ideas how to get back into Suse, I kinda like it and have put quite a bit of work into customizing for my taste. Don't really want to have to reinstall if I don't have to. Thanx for any help
