So a few days ago I took out my CPU's heat sink to clean it l. It went fine untill hooking it back up. It wouldn't POST until like 5 minutes later and when It did I would get a CMOS error,but couldn't access my BIOs. So I went through my rig and bare bone started and started full. Now it won't post period. Any help would be appreciated.
