You're not entitled for anything to run just because you feel like it should; specs matter.
Buying a "gaming" laptop was your first mistake.
Buying a "gaming" laptop with less than 8GB ram in 2015 is the second and biggest mistake.
However, Left for dead runs on pretty much anything, so if that didn't work, it just confirms that your system/install was fundamentally broken.
Well, you do realise your operating system is made my Microsoft and not nvidia/intel/amd/whoever right?
When you go through device manager to "update" the driver, it just scans your install for a driver, or microsoft's servers, which generally only have very basic drivers.
This is why your GPU has it's own control panel, there you can press "update" and you will always get the latest for your videocard.
Well a quick sure on google, the page you linked seems to be the first result, which just seems to be a product page.
The product is long discontinued so it makes sense that it's gone.
The second result however sends me -straight- to the driver page:
5 minutes seems like the proper average time for a driver update yeah, but even disregarding that, you just jumped through so many unneeded hoops and essentially wasted your own time.
