Hey everyone! Just today I finally got windows 10 to download and install, but with a major issue...

My GPU has been erased from the system

I have a Alienware Laptop
Intel i7-4710MQ 2.50Ghz (3.50Ghz Boost)
NVIDIA GTX 880M
and the newest version of 64-bit Windows 10

Went to open PS2 after it got set up and was running on integrated graphics. Went to change it in the GPU control panel, GPU control wasn't there. GeForce experience couldn't find it, nor could the NVIDIA website, nor the direct driver installer, nor was it in device manager, and it didn't even look like it was listed anywhere in BIOS.

So here's my problem, Windows 10 shut out my GPU it looks like, but how can I get it back? Any assistance is appreciated, and I should be able to provide most other info.
