his question seems to be whether or not a virus can hurt anyting besides the harddrive, not can to the virus heat up his computer if i understand correctly. no, a virus cannot hurt any hardware in your computer. it cant even hurt the harddrive physically. a virus is just software, i would recommend doing what ThatGuy16 said and scan for a virus, but if that doesnt find it just reformat and reinstall your OS. start fresh with your new case!
