Computer running very slow

Hello,
I have been on the computer for about 3 hours without shutting it off. Maybe that made it overheat? I'm not very computer savvy, but here is what happens:

When I have been on the computer for awhile, it tends to heat up quickly. After a few hours, programs and browsers are at a crawl.

It gets to the point where I need to turn off the computer and wait a few more hours.

How can I fix this? I ran my Norton antivirus to see if that would show if I have any virus or not but nothing comes up..
