Alright so I have an HP g62-340US got it bran new in 2011 for graduation. So it's not that old yet it's so slow I can barely use it iv considered the obvious such as viruses and malware which it has had both in the past, iv reset it to factory settings at least 6 times to rid the CPU of such things since it started acting up a year or so ago and continues to get worse. Iv upgraded the RAM, nothing I disassembled it cleaned the fan and still nothing. The CPU usage will hover around 70-100% just idling on desktop. I can't run any virus or malware scans cuz it always freezes it has a serious freezing problem I'm out of ideas not a commuter guy at all rly either so anybody able to give me some pointers or what I could replace or what's wrong with it? Much appreciated thanks!
