Hello everyone

I have a problem, I think it's a laptop problem but lately I have been experiencing a few problems with my computer on my laptop, when I plugged in my iPod touch today and opened Computer it just said "Windows explorer has stopped working" and it restarted the whole toolbar, and that same incodent happened with my External Hard Drive, is there something wrong with my external devices or is it my Computer? Just that I need to print some documents at Warehouse Stationary today and I need to know if it will effect their computer.
