Hello everyone!
I am sorry for any spelling/grammar mistakes as English is not my native Language. Also this is my first thread in this website and i apologize if this is the wrong category for this subject.

I bought a Dell Inspiron 7567 a week ago and i had a rattling issue on touchpad which felt like i could click twice with a single push. i tried to solve it myself and opened the back cover. I removed the battery, checked the touchpad area and put battery back on. I didn't manage to fix it. problem starts here; as soon as i closed the lid, turned the computer on and tried to play some games i realized a stuttering. Before this process i was able to play the most demanding games on high settings like Batman: Arkham Knight or Gta V with no flaws. The stutterings don't look like fps drops which you have with an insufficient gpu. They are more like random short continuous freezes. i tried reinstalling everything. every setting is same as the time when there was no problem at all. i tried using HWMonitor to see if it was a thermal issue but neither my cpu nor my gpu gets past 75 Celsius. And even more interesting my pc used to work at higher temperatures with no performance issues. now i have my pc like 5-10 degrees cooler but i am having performance issues on games. Also when i checked HWMonitor and saw my minimum clock speeds went as low as 800Mhz, without it going over 75C. when i disabled Intel speedstep from bios my games ran a bit more stable but that also locked my cpu speed to 2700Mhz even though i didnt disable the Intel TurboBoost and it was also lower performance than i first bought the laptop. The issue starts after a few minutes of gameplay even though there is no overheating in the computer.

I checked my windows power settings, did a clean installation of windows 10 64bit. reinstalled every kind of driver and tried pressing the power button for 5 seconds while battery is plugged off. also updated my bios.

Specs: Intel Core i7 7700 hq
Nvidia Gtx 1050ti mobile
16GB of Ram
1Tb HDD
128GB SSD
Windows 10 Home Edition 64-bit

So people, i am quite unhappy since this computer is a week old and i am desperate for help/suggestions.

Thank you in advance.

Thank you for your quick reply! Today Dell told me on a phone call that it does not void the warranty to open the back cover but since the warranty service is quite poor in my country i dont want to hassle with processes that can go longer than a month sometimes. Thats the reason i want to solve the problem myself. Also they would figure out that i opened up the computer by looking at screws.
