- Check for possible overheating or excessive dust
Remove the cover from your computer to check for possible overheating or excessive dust. Make sure your computer is in a cooled room and is free from dust. If necessary, use a vacuum cleaner with attachment to get rid of any dust. - Check your power source
Verify your computer is plugged into a reliable power source. Doing a voltage test may be necessary to determine fluctuation in power or if an adapter is needed. - Check your computer’s memory usage
When both physical memory (RAM) and virtual memory (swap space) are low, your computer may shut down unexpectedly. Verify that the RAM is adequate and the virtual memory is adjusted for optimal performance. - Update your computer’s software and virus protection
Ensure your computer’s software, operating system, and virus protection is up-to-date. This helps keep malicious software, such as spyware and viruses, from invading your system. - Run a hardware diagnostics test
Hardware diagnostics tests can help identify hardware related issues. Contact your computer’s manufacturer or technician for more information on how to obtain and run these tests.
