Suddently slower performance and fps drop on my XPS 15 (latest version)

Hello,

I'm writing to you because i got some issues with my XPS 15.

PC Specs :
Processor : Intel Core i7-7700HQ CPU 2.80 GHz
RAM : 16 GB
System Type : 64 bit
GPU : NVIDIA GeForce GTX 1050
Running on : Windows 10

Let me explain you the issue. When i bought my XPS 15, all was perfect, no issues. I started to play a bit, in-game the fps was perfect. I was at 100+ fps on HIGHEST Graphics Settings, in fight zones it was at 90 fps minimum (witch is really perfect).

Then my university exams were getting closer, and i decided to delete all my games on PC and start studying a lot more.

After the exams i re-downloaded some games, then i figured a huge fps drop. From the initials 100 fps it dropped to 35 fps (on the LOWEST graphics settings), it was going to 3 fps (in fight zones, witch is unplayable).I prefer notice you that i tried to do all in-game related changes. Then I started to search some solutions for that issue on google.

I tried a lot of things, like :

- Re-installing the NVIDIA Drivers (Clean mode). I even tried to run on "old" driver versions (i tried to run on the Nvidia Driver that can be downloaded on Dell Support Page).

- Uninstalling GeForce Experience

- Uninstalling some bloatwares

- Reinstalling games

- Reinstalling the system at all

While i was searching for a solution, i found a guy had my same issue on the same laptop (here's the link if u would like to check it out : http://www.tomsguide.com/answers/id-3334463/extreme-fps-drops-dell-xps.html). But in his forum discussion he put that, the pc in addition to a hige FPS drop was getting slower generally.

And i could notice the same double issue. In fact, my pc was getting much slower than it was (the startup was a little slower, but opening any game : was really SLOW. Like if i click a game (17 sec min to launch, compared to 3 initial secs), file explorer (at least 4 secs, compared to 1 initial sec), firefox i was "waiting" for it for at least 5-6 secs. When i just bought the PC, it was 1 sec max.

Then i tried other fixes :

- I disabled a lot of software on Startup

- I put Battery Power Options to the Maximum (High Performance)

- On some forums it was written that my wifi connection could be the problem (related to FPS), so i bought a Dell USC-C Adapter and a NEW Etherent Cable cat6. Witch made me boost my Internet connection (even if before it was excellent too).

The Graphic Card i got is an NVIDIA GEFORCE GTX 1050. On games i was playing, it should be even "too much". Because i don't really like new games, so i play at some old games (better saying, at old "versions" of new games).

The thing i can't understand the most is, that i done no changes on the PC until i discovered that FPS Drop. At start i was even thinking : "maybe it's just today, it will be better tomorrow", "it's not an issue based on my new XPS 15 that i paid 2k euros". But then after 1 week i couldn't believe in it anymore.

I rather let you know, I'm open to do any tests on the PC, anything it should be necessary.

Thanks for reading, and i hope there will be a solution for my issue that u will be able to find rapidly.
