I purchased used laptop DELL i7-6700 HQ CPU@2.60Hz/ 16GB general ram.
1. The seller told me that the Laptop has two Graphic Cards (a) 4GB-Intel(R) HD Graphics530, (B) 4GB-NVIDEA GeForce GTX 960M.
2. In Device Manager, when I clicked on NIVIDIA Card for information, a message appears that the windows stopped the NIVIDIA Card since there is an error and Error Code-43.
3. I found that if I don't install GeForce Experience (hence no updates from GeForce Experience, the NIVIDIA Card's properties are showing that "THIS DEVICE IS WORKING FINE." If I install GeForce Experience, error 43 appears with a yellow triangle on it in Device Manager.
4. So, I removed GeForce Experience & its basic drivers, cleaned the Laptop with local disc-C, re-installed OS, restarted the laptop and the Widows downloaded the basic driver for NVIDEA Card and now NVIDIA Card's properties are showing "THIS DEVICE IS WORKING FINE."
5. Now in Advanced Display Settings, it shows
Total available graphics Memory: 8254 MB
Dedicated Video Memory: 128 MB
System Video Memory: 0 MB
Shared System Memory 8126 MB.
6. Now Can I think that both the graphics cards are working by showing (InTel + NVIDEA 4gb+4GB) Total available graphics memory as 8254 MB and I can only take updates of the graphic cards only from Device Manager and continue like this without installing GeForce Experience? Is it right Sir? PLEASE ADVICE ME SIR.
