Well we need to narrow it down a bit, so Right Click on My Computer, click on Properties then on the Advanced Tab. In advanced go down to Startup and Recovery, and click on settings. In there un check "Automatically Restart". and O.K. your're way out. The next time the error happens, a Blue screen should come up giving us more info on the error. Copy the error. and post back. See what we can do then.
