Could be many reasons. Update your drivers and graphics card is the first thing you should do. Second, check if it's not overheating issues. Beyond that, ask again after you checked both of that.

yeah i have checked all of thats and i found it. but my problem have solved.. ty for your help 

Hi, i wanna ask about how to remove bloatware from my  aspire vn7-592G and i wanna know also about the list of bloatware on my 1 week acer laptop. i dont know what bloatware to remove. Im kinda afraid if i remove everything that will harm my laptop.

Nuke and fresh install Windows 10.

As mentioned by voncrane, share what the cause was and how you solve it. Will be useful for another person to know.
Agree with voncrane here. However, remember to get a list of relevant drivers for your specific model before nuking and get all of that after fresh install.

Yeah.. Omitted that part cuz that's a given.. I mean, who goes and does a fresh OS install without downloading drivers first.. .. Especially WiFi drivers if no easy access to an ethernet connection..

You just never know lol. It might be the first time nuking and installing Windows for some people and I wasn't sure if kunkamal is a newbie or someone experienced.

Haha, im still newbie about a laptop. i solved this problem after i add my m.2 slot with 128gb ssd and add 4 gb ram to my laptop. i play game smooth after that. aspire vnitro has lack on battery performance thats what i see until now..

any og (vn7 591g) v nitro users have replaced their battery? how much, did you go thru acer service centre or from 3rd party?

Didnt change battery but got my whole keyboard + palmrest changed by one of the lyn member, Incore Trade Enterprise. Very fast and cheaper price than acer service centre. Last time i go acer service centre do cleaning and reapply thermal paste only already $150, not even good thermal paste they used stock one for me since I requested and they said don't have and need to leave laptop there for at least 3 working days

May i know if this ssd fits into my VN7-591G-744N?

For those with cooling problems i found a way to control the both fans speed , and i think that auto fan speed never use the full potential of those fans , because i got even 94°C cpu temp and the fans sound aren't nearly close to the nousy sound when i set them to max speed.
You need to download rw everything from here http://rweverything.com/ and launch it , then select the "EC" tab that is circled in screenshot.

Then go to 90x03 that is for right fan near the GPU , it should h;ave value 04 for auto fan speed , you must modify it to 14 for manual fan speed then you can modify the speed in the next column (90x04) with values from 99 to 60 , where 99 value is the lowest speed and the 60 value the highest speed , in the next column (90x05) you will see the actual speed of the fan
For the left fan near the CPU go to 90x06 and do the same thing: 04 for auto fan speed , 14 for manual fan speed ; and in the next column (90x07) set the speed with values from 99 to 40 , where the 40 is the max speed of that fan.
With the fans set to maximum speed , i never exceed 65°C in GPU and 80°C in CPU that is set to run with all four cores to 3.5GHZ from intel XTU.
I think that the cooling system potential on this laptop is more efficient than the one from asus G571 which is giant.
I hope that was useful for those with high temp problems.

hi guys, my v15 fn key is not working now, happened suddenly, any1 have and clue to fix this?
