When in safe mode go start->run-> type in "msconfig" -> click autostart tab, then uncheck all unnecesary programs google the ones you are unsure off. If nothing in software way works open your computer up and make sure nothing isnt stuck in your fans or maybe it just needs to get vacumed. Opening your computer might break your warranty.
System restore restores the system back to a later date, so If something bad happens you can restore it back to before that. Go to accessories>system tools> system restore.
