Computer only restarts - won't load up

Hi, my friend did a complete wipe and fresh re-install of windows/programs.

I've used it very little. Today it was really lagging and unresponsive so I pressed the off button, waited a few moments then turned the computer on. I got the screen that asked if i want to load safe mode, last known good config, or start windows normally. I chose start normally. it started to load windows then a very brief bluescreen popped up and it restarted. I tried last known good config, and the same thing happened. I tried safe mode and it still happened. I tried taking the battery out for a little bit then booting it up again but still the same issue.

I have no idea what to do :( Help?

It's a toshiba laptop with Windows XP
