Big problem with my laptop

[jdeprince]

I wasn't sure of where to put this because the problem I'm having falls into a few categories, so I hope this is the right place.

Ok, so I got my new laptop for school (an IBM Thinkpad T43) this summer, and its been running great up until now. But then went I went to start the computer today, I loaded up Firefox and noticed that all of my bookmarks and saved search bar engines were gone. All of the other extensions and add ons work, and I can still go to different websites normally. I assumed this was just a Firefox problem until I realized that everytime I press the back button on mu keyboard (the button located above the left arrow key that functions and the back button in web browsers and as well as when navigating through folders) the computer freezes. I tried restarting, but that didn't do anything. So then I ran a virus check, spybot, and scan disk, all of which didn't fix the problem. One other thing I've notcied was that the My Computer screen looks different from how it usually looked. Instead of the different drives being seperated, they are all grouped together like it was any other folder. I'm really stumped about what could be wrong and any help would be greatly appreciated.

Also, I started in Safe Mode, and everything was fine.

Thanks for any help.

To be more specific about the freezing.. the computer doesn't completely freeze. I can still move the mouse, and there are still programs running, I just can click anything.

I would suggest running a virus and spyware scan. Also maybe post a hijackthis log in the cyber safety forum and someone will look at it for you. See this thread

The virus and spyware scans found a few bad items, but it didn't change anything. I'm going t odo the hijack thing and hope that works. Thanks.
