lagging while playing videos and games

Hello, my laptop is Intel i7-3537U, 8GB RAM, display adapter Intel HD graphics 4000, and a few weeks ago my computer started showing problems when playing videos - serious lagging when playing Youtube or Netflix on Chrome (didn't try on other browsers), and also lagging and slowness when playing Might&Magic X - legacy. The lagging started only a few weeks ago, I think after Windows automatically installed updates. I tried defragmenting, did a thorough virus check and disabled all unnecessary programs at start-up. Is there anything else I can do?
Thank you

Do the videos lag or do you mean that they don't buffer properly? That means it a slow connection. Not much I can do to help on that though. (Other than use cable instead of wireless if you can)

Check your power setting is not on power saving.

My power settings are indeed on Power Saver. I tried to change it to high Performance several times, including restarting but it keeps changing back to Power Saver. What can I do?
Thanks

By what I saw, It's lagging for streaming more than for buffering, but does lag in both cases. Also on games.

You could try monitoring your temperatures.

Do what you usually do (play games/watch videos) until you start to notice the lagging. Have HWMonitor running in the background before you do so, then take a screenshot of it and post it back here. It's possible that your CPU is overheating.

You could also try downloading the latest Intel HD drivers.

I downloaded the latest drivers last week, and it didn't help. I'll run the HWMonitor and post it back. Thanks!

I used HWMonitor while playing Netflix, and video lags badly. I can't post the print screen here apparently, so I'll describe the differences:
Temps of TZ00 and TZ01 increased from 48 to 54;
Vid voltage decreased from 0.821v to 0.796v;
Temps of Core0, Core1 and Package increased from 47-48 to 53-55;
Powers of Package, IA cores, GT and Uncore changed from 2.43, 0.42, 0.01, 2.01 to 4.74, 2.09, 0.3, 2.34.

The rest remained the same.
Thanks again
