Ive recently bought a new laptop, with windows xp etc. however, if I click on My computer, then c:, and then windows, the computer freezes, and comes up with an error screen (windows explorer has encountered a problem and needs to close).

I have tried re-installing windows, without deleteing anything, but to no joy.

Sometimes another box pops up telling me about Dr Watson Post Mortem Debugger not working.

I'm not particularly PC minded, so can someone help?

Thanks
