Oh sorry! Its an inspiron 510m, and its the same thing every time I start it. Its a laptop. I suspect it has something to do with my wireless network card, as during the last week, while it still actually worked, it crashed twice and told me my driver wasnt up to date enough, so I downloaded something from the dell website, an intel-pro wireless network something or other. Any ideas?

Which computer model and which operating system.  If you power down the computer and restart, the same thing each time?  If this is a desktop are any of the diagnostic lights lit on the back or front of the computer when the problem occurs?  Any software or hardware changes lately?  Details!!!

Sorry, I don't know much about the Inspiron line and you may want to post in that forum.  Can you easily remove the wireless network card and try a restart?
