Computer Quickly Restarts Once Starts

Let me just say I'm not the computer savvy one in the family, waiting for him to get home later. So once I would login to windows I would get about 2 seconds before the screen would flash blue and I'd get some message I couldn't make out. I did some searching on your forums; and have now logged into safe mode, turned off the automatic restart and here's the error I get on the blue screen: A problem has been detected and windows has been shut down to prevent damage to your computer. If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again follow these steps: Check to be sure you have adequate disk space. If a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters.
