My laptop had Window Vista on previously (sorry). Something went wrong, I can't remember, and I tried to reinstall but couldn't, installed a replacement second hand HD, and installed Ubuntu instead. It worked ok for a little while, before crashing. I ended up reloading Ubuntu three times. It works for a while after (say 3-5 hrs of domestic web browsing), and then crashes.
When I turn it on now, it comes up with some options to restart in safe mode, run tests and so on. I can't get it to start normally. I'm not going to re-install again.
Below are screen shots of what happens when I follow some of these test options. These screen shots mean nothing to me. Any ideas? Surely I can fix this....
