Processor is hot

Verify that airflow to the computer is not blocked.

Verify that chassis fans are connected and working properly. Some fans operate only
when needed.

Verify that the processor heat sink is installed properly.

Hard drive is full

Transfer data from the hard drive to create more space on the hard drive. Microsoft
recommends at least 200 MB to sync system files.

Perform disk defragmentation to consolidate fragmented data on the hard drive so it
will work more efficiently.
