In January, I installed Windows ME on my Acer. Had some
conflicts which do not allow me to ever restart. Have to
shut down and then turn back on again. My brother visited
last month and "helped" me with installation of a CD
writer. While online, the "automatic update" window came
up, so he selected everything and hit download. Then, of
course, he hit restart.
Computer hasn't been the same since. Everytime I start it,
I get this message:

OE:0028:00000002
or
OD:0028:00000003

Anyone have any ideas how to fix this?
Thank you ever so much.
