Usually when playing videos or more demanding programs on a laptop, I make sure that the power setting is on Balanced or High Performance.
It's something you may want to check.

You also may want to try running programs with your security programs disabled. Disconnect from the internet, first.
If your programs run fine, then it's probably a security program that's causing the issue.
