Seems like a corrup windows install
Just try to repair windows or factory reset
Your PC is more than enough for common tasks that you have described.
Your video card is suitable even for modern games, but your dual core CPU may limit your gaming capabilities.
Check your HDD for viruses and errors or reinstall OS. You have good hardware (except something of that may be faulty)
the HDD is using like 99% when in chrome may that have something to do with it?
