Ok, this has been going on since February. I have AOL open all the time while I'm at work. I'm also usually running quickbooks 08, and other various documents. It doesn't happen all the time. Sometimes it doesn't happen at all! Other times it happens as many as 6 times a day. I will go to click on my mail and bam everything shuts off and reboots no error code, nothing just reboots! I have been in contact with Dell support. They have tried all kinds of things and can not figure out what is going on. I uninstalled AOL and reloaded it hoeping that would fix it but to no avail. Now not only does it shut down when I click on my mail it also shuts down when I switch from one screen name ot another. This is a major problem!! It is very frustrating. Any help would be great! Thanks
