speeding up or changing laptop Intel HD Graphics 4000

My laptop has an Intel i7=3610QM CPU @ 2.30GHz, 8GB ram and a fast 1TB ssd.
The slowest part of the system is the Intel HD graphics 4000
The laptop originally came with Windows 8.1 which I upgraded to Windows 10 home (now ver. 1804).
Ever since I upgraded to W10, the graphics driver has been a problem: blank screen on waking up, slow graphics.
Because the laptop came with W8.1 the manufacturer's website (Toshiba) does not have drivers for W10 for this laptop (S855-S5254). That is why I downloaded a driver from the Intel website.
I updated the graphics driver to the latest I could find version 10.18.10.4885 dated 12/11/2017 at the Intel website. It helped a bit but not much.

Is there anything else I can do or tweak to make the graphics less of a bottleneck?

I'm no expert but I think this graphic chip is part of the cpu, so there is no way to change it. Correct?

Anything that would help short of buying another laptop?

Thank you.

Install the Intel Display Driver and the AMD Display Driver. Also, you need to update your Windows 10 version to 1803 (OS Build 17134.191). That's the latest public update.[/QUOTE]
Thank you so much!
I am not sure I understand. How can I use 2 drivers? Why install the AMD driver?

Will the next w10 update add different drivers again reversing what I did?

I went to the website you gave me but I can't seem to download the drivers. Clicking on them does nothing including right clicking.

Please ignore. I went through the initial steps and then all worked.

Thank you for the speedy response and help.
I did as you said and rebooted.
Now the driver is much older than the one I had. Hope it solves my problems.

It's not older: The version you downloaded from the Toshiba site is 10.18.10.4885 dated 12/11/2017.

So I must have done something wrong. I downloaded both files and ran them. Then rebooted and went to the device manager and what I sent you is what I saw in Device manager, dated 2013.
That is why I was surprised. Did I miss a step?

Here's what I found on the Toshiba website

Aha!
So, I'm OK?
