First of all, you need to find the cause of the problem. Is your cpu fan running? or as previously stated, is it clogged with dust? is your heatsink properly mounted with thermal paste between the cpu and the heatsink? After you find and fix the cause, then look for a program to monitor the temperature. Try going to the motherboard manufacturer website and look for utilities to monitor cpu temp. You may also try going to bios and check to see if there is an option to give a warning for cpu temp. By the way did you get your recycle bin back?
