One out of every two or three times that I return to my
computer after having the screensaver running, my screen
displays only a full-screen image of consecutive rows of
colored vertical bars. I believe that my mouse is still
working but nothing else--no task manager, no login, no
task bar, etc...I have to restart--multiples of ctl-alt-
del works for this, and after a reboot everything is
normal again. I've ran an antivirus program with updated
definitions and also spyware programs but to no avail. Can
anyone help?
