Hello. My name is ***** ***** I will be assisting you today.
Did you download driver from here? http://us.gateway.com/gw/en/US/content/drivers-downloads
This particular model is not supported for Windows 10, it only has a BIOS version up to Windows 8.1
You can try this download and see how it reacts. http://global-download.gateway.com/GDFiles/BIOS/BIOS/BIOS_Gateway_P01.A2_A_A.zip?acerid=635040993388166881&Step1=DESKTOP&Step2=DX%20SERIES&Step3=DX4870&OS=ALL&LC=en&BC=GATEWAY&SC=PA_6G
run the file BIOS_WIN.bat in the WIN folder.. not sure if it'll work on Windows 10 but worth a shot
