Hi, I'm having little problem with my graphics that isn't urgent, but is sometimes annoying and inconvenient. Device specifications are below.
I bought my laptop about 1.5 year ago. For the first week or two I had problems with BSODs, some random and some related to my graphic card. Problems were progressively disappearing with time and I don't really know why. Problem with graphics diminished after reinstalling software and drivers for graphic card. I also did basic research for solution and explanation of other BSODs. What I remember, it had something to do with OS sleeping mode enabled, but it didn't solve my problem. I just learned to live with it and after a few months all more serious problems were completely gone.
The problem I'm having remained though. There is a basic pattern describing it. When I play the game I will have either no stutters at all or stutters will appear every few minutes or seconds. It's interesting that each time I start a game the time interval between stutters seems to be constant for that particular run. It usually doesn't change when I restart the game, but changes when I restart laptop. The stutters themselves last for about 1-3 seconds. During that short time my fps count goes down to 20 and below, depending on my initial max fps. Weird thing is severity of stutters varies most between days, so when they appear I usually give up playing that day. One day there may be no stutters, other day games may be nearly unplayable with stutters every 5 seconds (such days are very rare though).
Important thing is sometimes in some games other people see me lagging while my game is stuttering and fps is going down (e.g. CS GO), while in other games the connection stability warning appears (e.g. Rocket League).
Now it may be relevant to say that my wifi card doesn't seem to work well. I am used to having problems with connecting to networks. Sometimes my laptop doesn't see any networks at all. Upgrading to Windows 10 seemed to help there a little. Wifi card was the first thing I blamed for all problems, but I didn't verify it in any way.
Another important fact is my laptop came with Windows 8.1 and upgrading it to Windows 10 didn't make any difference. That's why I'm assuming it's hardware related problem. While being on Windows 10 I visited support page for my model and reinstalled all available drivers. Updating UEFI helped the most, as the time interval between stutters increased greatly.
Today I decided to put up quite a fight with my device and diagnose all problems. I will be grateful for every advice. Buying new hardware is the last thing I will consider and I would prefer not to. Please advice me on what to do first to narrow possibilities. I am ready to use heavy weapons.

Few days ago I experienced BSOD loop after installing drivers for Xbox One Wireless Controller and asked for help here on this forum https://www.bleepingcomputer.com/forums/t/636533/constant-bsod-related-to-xbox-one-controller/. This problem is solved by now.
