Hi all, My 300-MHz computer with Windows 98 had been running continuously for months without a problem, but now it started to quit after running 8 to 10 minutes. When the problem occurs, everything on the screen blanks out except a blinking cursor in the upper left corner. Ctrl-Alt-Del does NOT bring up the window showing a faulty program. I have to reboot to continue operation (boot process is normal). The only change in the system occurred a week ago when I installed a 17-inch monitor. Since the existing driver performed so well, I did not install the driver for the new monitor. Everything was OK for a few days. Could this have led to my present problem?
