Hello, I have a problem with my Nitro 5 AN515-54. It used to work perfectly until this week where I had a sudden FPS drop in EVERY game. Like from 120 to 40. When I investigated the problem I found out that when gaming my cpu clock speed drops to around 1.5 GHz sometimes even lower to 700 MHz. Which is ridiculous My processor has a base clock speed of 2.6 GHz an it boosts to 4.5 Ghz. I should easily get 3.5+ Ghz clock speeds. I should also add that while web browsing or doing something other than gaming like using MATLAB or just web browsing, my clock speed goes up to 4.1 Ghz. which i find very weird.
I tried many many solutions but none helped. I even tried cleaning fans and re-applying thermal paste but nothing changed. I tried updating every driver, I tried re-installing a fresh Windows. I tried multiple games. I tried controlling cpu clock speeds using throttlestop. I tried undervolting for thermals. Nothing worked. It's making me crazy.
Please help if you can. I would gladly try every fix proposed.
My PC specs:
Intel Core i7 9750H
@2.6GHz (4.5GHz Turbo boost).
RTX 2060 Mobile 6Gb of VRAM.
16 Gb RAM dual channel.
1080p@144Hz Monitor.
Here are some screenshots of my pc performance:
One is when i'm web browsing (Also included some of the games that I usually run very well, just for reference).
One is when I launch and start playing Sekiro (60 FPS
@2.6~3.1GHz).
And the last one when playing for a bit (40 FPS
@1.2GHz).
