It sounds like it's overheating. How old is this PC? Have you ever opened up the case & blown the dust out of it? If not, it might look like this: https://en.wikipedia.org/wiki/File:...

It is about 5 years old. Its Monitor and computer all in one type of PC. I was thinking the same thing. It may be so clogged with dirt. I will take compress air hose to it. Thanks

If you can get to the CPU heat sink make sure you clean that as well as the vents and fans.

Always pop back and let us know the outcome - thanks

Also blow out the power supply from both ends. You may want to take the case outside as it will be messy.
