Hello!

Not long time ago i bought myself Acer V15 Nitro laptop. GeForce GTX 860m Intel Core i5 4210H 2.9GHz 8gb RAM dysk SSD / HDD

.. And i got problem with it. When i play games im getting stutter / fps drops. For example on cs:go it goes like : I play 5 minutes > I got freeze for 2 seconds > I play one minute > I got freeze for 2 seconds > I play again.... and on and on...

In World of Warcraft its bit different because instead of freezes im getting huge fps drops every few minutes.

Things i tried already : /Setting fresh system /Reinstalling windows between 8.1 and 10 (same problem on both) /Getting new drivers / older driver versions for my graphic /Closed background programs while playing

Nothing seems to work. Any ideas what else i could do? Thanks for any advices and sorry for my poor english :|

Since it's a laptop I would think it is thermal throttling. That is when the cpu and gpu are working hard, heat up and slow down to prevent overheating. You could get a cooling table to cool it.

I've got cooling pad. Without using pad and just after the "lag" i took these screens. Btw. some of these are in Polish but i think you can manage to understand it.

Your pc is definitely thermal throttling. The cpu was as high as 91C and the gpu was up to 78C which is way too hot. You may want to replace the thermal paste on the cpu.

Photos arent best quality but...

Its part of 1st photo from 1st link.

You can see there bottom of my keyboard. I found strange that there is foil all over this metal bottom of my keyboard (red border on image 2). I can guess that its there to prevent any damage dealt by this metal to main board when you put everything back in. So i guess it have its prupose but is it really needed there? Problem is that its slightly going aboard to the vent area. It is kinda blocking air circulation there isnt it? Should i cut this part (blue border on image 2)? it might be issue i guess... Is it safe to remove it?

I wouldn't remove it if you don't know why it's there, that might have unintended consequences. So have you looked at the cpu cooler? Try to clean dust from it.

Every little bit of dust removed. Still bad temperatures and i still couldnt unscrew one screw to replace paste on CPU. :(

 

I have question : Can i add more paste to old one? I cant remove cooling system but i can manage to add paste with stick or something. I cant clean old one tho. :/

Don't add more without removing the old paste. That will actually have the opposite effect. See what you can do to remove that screw.

Removed old paste and applied best i could get. Didn't help too much.

 

By the way can someone give me links to programs that are able to check temperatures live and can force to be on top of screen?

I want to see temepatures non-stop even when playing games. Is it possible?

 

 

Also is it possible to lock my laptop in bios to close windows at 95C?

If you have an external monitor you could hook the laptop up to that to read temps

For the second part... I'm surprised at such high temps the laptop didn't shut down by itself. It should be a setting in the bios.
