GeForce graphic card not working due to upgrade window to 8
I'm currently using my laptop with i31.4GHz processor. It also runs with 4GB RAM and a GeForce graphic card. It works fine with my Windows 7 enterprise Edition. But after upgrading it to Windows 8.1, my games are not running correctly. I already updated my graphic card driver, yet it is still the same. What else can I do?
