Antivirus.  Is it up to date or has it expired?  I receive calls from customers after the antivirus has expired. The anti-virus sometimes needs to be renewed.  Some internet service providers (like Comcast, CenturyLink) often provide full anti-virus protection with your internet subscription.  There are free versions for anti-virus also.  I’m a reseller of Panda Security Products and EndPoint Protection and would be happy to help you with adding protection to your personal PC.

Compressed Air – use to blow out the vents and keyboard.  Do a google search to find out how to do this on your make and model.  Buy a can or two of compressed air at Staples or Office Depot, or on Amazon…The process is different for laptops and CPU’s.  On a laptop use short blasts and make sure the vents aren’t blocked (sometimes on the bottom of your laptop). For a CPU you may need to remove the outside case.  Oh, the things you will find 😊 I’ve seen some laptops that were so dusty there were dust bunnies keeping the fan from spinning, and it was not cooling the laptop.
Here are pictures inside a dusty desktop PC (which had been on the floor, running for more than 2 years)
