Is my laptop bottlenecking?

[CS_Calm]

Hello!

I brought and customized this laptop myself two year ago, and it has been having issues playing any games at all, since I first got it. Even a game of Chess, I find it to be laggy and unresponsive after opening and closing the application.
I played League of Legend, it start off fine but lag incredible high after a few small particles appears.

CPU: Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz.

Graphic: Intel(R) HD Graphics 4600
NVIDIA GeForce GT 740M

I wasn't an expert building this laptop, I thought the NVIDIA GPU and CPU would be a perfect fit, but I guess not.

EDIT:
Quick little update, I notice the temperature of the laptop is usually high. It stay stable at 75-80 Temperature.
I think it's more of an overheating problem.
I blew the fan to remove any dust, but that doesn't lower the temperature a bit.

Anything I can do about this?

Hi,

I would suggest doing a clean install of the graphics driver.
- Go to Device Manager and uninstall the Nvidia graphics driver.
- Next is to open Programs and Features then uninstall anything related to Nvidia.
- Once completely uninstalled, download and install the latest driver.
- Reboot the laptop once the latest driver has been installed
- After the reboot do also set Nvidia as the default GPU.
- Here's how:nvidia.com/Download/index.aspx

Does the laptop have the latest BIOS and mobo drivers? What laptop model or where did you get the customization from?

Yes, ,it is updated to the latest BIOS, where can I locate the motherboard drivers?

I cleaned out the fan, but it's still operate between 70 and 90, when being used.
