things go blank

Hi marry and a happy!
I have just formated and reinstalled windows XP on a computer that I had blender on for the past year or more and now when I do some work on blender after about 5 miutes the panels on the interface go blank. If I move the cursor around the panels the ones it gos over will apear but then they go blank again when I move over another area.
I have redownloaded and reinstalled a bunch of times, trying different things, but no luck sofar
thanks for any ideas and help

Sounds like a graphics card driver issue.
Check the manufacturers site for updated drivers.

Yeah I had the same problem on my last computer. It was the graphics card as this one has a much more powerful one and Blender runs like a charm.
