I came home yesterday to find no desktop on my pc. E-Mach. t4010. After shutting down via Cont-alt-del, the machine would start normally but every few seconds the desktop would go off and then come back on again. If I am fast enough I can get IE to come up so I can get on line, but eventually after several times the desktop disappears and all I get when I move the cursor to the taskbar is the old hourglass. I tried to restart in safe mode and all I get is a black screen w/ "safe mode" on the bottom corners. I tried to restore to an earlier time and the only restore point I could access was from the night before. I could not go to the previous month. At one point I did get a pop-up about bdsr, so I googled that and got to you. I have looked at Techspot's post from Po'girl and downloaded the suggested programs and ran them, so far to no avail other than my wallpaper disappeared. What next before I decide to restore the system.
