I've been having problems with Linux Mint on my laptop for the longest time. I'm still a noob at using it but I've done a lot of searching on the forums and on google. I still haven't been able to find a solution though.
Last year (or the year before), I installed Linux Mint version 11 for the first time. Everything worked great except my computer kept on overheating and would shut down randomly. My laptop runs a lot hotter on Mint than Windows for some reason. My laptop has an ATI Radeon 3650 card in it, and I found on the forums that ATI drivers and Catalyst Center would be needed. So I installed it but it didn't seem to help, and my computer was still overheating.
Last week, I decided to upgrade to Linux Mint 14 Xfce to see if it would help (I did a format and install). It didn't and my laptop is still overheating. Running sensors, I could see the cores go up to 86 degrees C. Thinking it could be the video drivers again, I tried installing the ATI Catalyst Control Center but I am having a lot of trouble with it. It appears that the latest drivers on ATI's site for my graphics card doesn't work well with the current kernel version on Xfce. I looked and found the guide linked below for installing version 12.6, but it seemed to have failed since running "fglrxinfo" still shows error.

I don't know what else I can do. I like using Linux but it seems to crash my computer more than Windows. I would like to try getting the Catalyst Control Center and driver software in Linux to see if that would help, but I doubt it will since I managed to install it before on an older version of Linux and I was still having the same problems. My laptop normally runs at 40 degrees C on windows but it's doubled in Linux Mint. I checked the bios and I didn't see an option for fan controls. I opened up my laptop and made sure all the dust was cleared. I have to use two laptop fans in order to keep my laptop around 80 degrees C in LM. Any ideas on what I can do?
