Hello,
I have problems with my new DELL laptop I5 7300-HQ GTX 1050.
Every game I run, CPU jumps directly to 100% and laptop overheats.
I tried fixing options:
Disabling SuperFetch,  disabling Windows Update, disabling because my DISK was also spiking at 100%.
I have updated all drivers to up to date and it didn't fix the problem so I reinstalled windows in order to see if any corrupted windows files did this but the problem is not fixed.
In games I don't have low FPS only high CPU and high temperatures.
I have even disabled Windows Defender, as well as other stuff like Telemetry from regedit but problem is still not fixed.

Then with reinstalled windows I tried again disabling windows services because in my resource monitor system was writing a lot.At the moment I am doing a LoL update and SYSTEM is writing between 10,000,000 -21,000,000B/sec and disk is at 100%.

Also there is no hardware problem as I did multiple full scans showing no errors and no antivirus problem.

If anyone knows anything to fix this, I would be more than thankful to try it!
