Sounds like a video board/driver issue. I'd get the latest from your board
manufacturer's site for your specific board. I'd also fiddle with your
Display Settings (Resolution, Color Depth, DPI, Refresh rate, etc). If none
of that helps and you cannot live with this issue (it is after all just
cosmetic) you might buy a new video board.

...
When scrolling down a worksheet rows will become grey. It doesn't happen
to
every row. It does happen everytime I scroll down using either the
keyboard
or mouse. I have replaced both keyboard and mouse, removed and
re-installed
Excel and it didn't correct the problem.
The rows that become grey have not been filled with a color. Sometimes it
will fill only half of a row.

My co-worker has seen this before and he had to rebuild the computer.
Does
anyone know if this can be fixed without reinstalling windows?
