[Shayabuza]

hello,

i've got a laptop with following specs:

CPU:
Intel core i7-4500 gen 4th 1.8 Ghz

GPU:
Nvidia geforce 740M

RAM:
4GB

OS:
Windows 8.1 now

HDD:
1TB


before, with this spec i can play fallout 3, fifa15, nba2k15/nba2k16, borderland 2, and cs go without lagging but after one year my laptop lag just for fifa 15 and then i update to windows 10, all game below, i play for 2 minutes and it's lag for no reason. because that lag i change the setting to low but still after 2 minutes it's lag if i minimize the game and open the game again it run smoothly for 2 minutes and then lag again. and i downgrade the windows to 8.1 but still lag, maybe it's the hardware or can somebody explain this error.

P.S:
Sorry for my bad english

Hi,

Try to update the graphics card driver first.

- Go to Device Manager and uninstall your NVIDIA graphics card.
- Uninstall anything related to NVIDIA as well in Programs and Features.
- Download and install the latest graphics card driver from NVIDIA support site.
- Here's the link: nvidia.com/download/index.aspx
- Reboot the laptop once the driver has been installed.
- After the reboot make sure that all games are set to run in NVIDIA High perfromanance processor.
