Random and sudden performance drops.

I'm using "Dell Inspiron 15 7000 Gaming" laptop.

CPU: Intel i5-7300HQ

RAM: 8GB

GPU1: Intel HD Graphics 630

GPU2: Nvidia GeForce GTX 1050

So something like half a year ago my HDD that came with the laptop died on me. I had only 250GB SSD so I replaced it with that. It was crucial bx series SSD. But yeah - everything was working fine as before. And yesterday I decided to get 1000GB SSD. Also Crucial and the same series. Installed windows on it, downloaded drivers etc. And now my PC is acting very weird. When I play League of Legends my fps will suddenly drop from 140fps to 7fps. Path of Exile is unplayable. It constantly freezes up or just closes all together. And I was able to play both of those games without any problems before. I haven't changed anything - other than SSD.

I tried adding performance power option, as I didn't have it freshly with windows install. Couldn't do it trough registry edit as there wasn't a file that I was supposed to change so I ended up using CMD to add that power plan. Then trough Nvidia control panel I changed LoL and PoE to use Nvidia graphics card. (PoE even shows in settings that it's using Nvidia card). I tried changing two more files in Registry that were recommended to me which at first felt like it got better but by the end of the match in LoL it started to happen as often and as drastic as before but could be some outside factors. So I played a game of LoL in window mode (by the way doesn't matter if I'm playing on lowest settings or highest - it's still the same situation) with task managers performance on the side. So I noticed that while everything is good - my CPU is at ~80% usage and both GPU's at ~30%. But when I get those sudden FPS drops then CPU drops to nearly 20% and both GPU's drop to like 5%.

The oddest part is that when I'm playing Forza Horizon 4 which is much more intensive game on PC parts - it runs just as well as before.

Honestly, I've tried everything I could think of and the more I tried to look at what's happening the less I understand. I have no idea what is going on and how could it might have started from just and SSD change. I haven't added any ram or changed anything on this laptop.
