So I've been using this laptop for a while and it's been great, high fps on all the games I play, it's running a I7-9750H, RTX 2060, 16GB RAM and a 1TB SSD and it was working fine until I decided to disassemble it, and take a peek at the cooling. One of the screws for the CPU was broken so I couldnt fully so I lifted it up a little to see most of the cooling system and a lil of the GPU. I also removed the SSD and RAM sticks to check them out, and then put them back. When everything was reassembled, Windows was corrupted (still booted though, a bunch of random BSODs though) and there were a bunch of other problems. Reinstalling Windows fixed all of these problems, except one. The CPU refuses to go above 1.5Ghz when gaming. The temperatures were as normal (around 90-92), but the laptop could still boost and run fine before all of this. One thing I noticed is that it likes to boost to around 3-4Ghz when not focused on the game (aka alt-tabbed), it also boosts when it's not running anything intensive. As soon as i alt tab out of the game, it goes straight up to its normal speeds, aka 3-4ghz
Another thing I noticed is that games only take up about 15-20% of the CPU. (only checked CSGO so far)
CSGO used to run at about 200-300 FPS, now it only runs at around 90fps, sometimes going up to 120.
Another thing I did before this was undervolt it using throttlestop, but now that I have reinstalled Windows (and reset the CMOS) I assume it is not related to this issue.
