Sounds like hardware failure.  First consider overheating and check for 
a stalled fan, including the one in the power supply.  If it isn't a fan 
failure, backup your hard drive to another drive asap.  Hds often go 
intermittent before failing completely but the opportunity to save your 
data is limited.
