What you are experiencing are the early warning signs of disk drive
failure or over heating problems.
Before doing any thing else make backup of your user data if you have
not done so already.
Then open your box and use a small brush and a can of compressed air to
blow the dust off the motherboard and the fans. Give special attention
to the fan in the power supply. If PC is older than 3 years or has over
1 year of continues use then replace the power supply.
IF problem still happens replace hard drive.
