Can an external laptop power supply go bad in a way that would mess up

My 1800T laptop recetnly started showing signs of a problem.
About 2 weeks ago, on boot, (with the external power supply), I would
get 3 beeps. But no sign of a problem.

on reboot, it started normally.

The next week, on boot (with power supply), after showing the Compaq
logo, and with Windows starting, the display would go fuzzy in a pixel
manner. Upon reboot, the display would also go white in a gradational

However, when I switch power supplies, the problem seems to go away.
It's only during the boot that the video problem occurs, and if I

battery or using my alternat power supply.

Is it possble that the power supply was causing the video issues, or am
I just trying to keep from admitting that my machine is starting the
long slow decline?
