Format: Laptop

Device Make: ASUS

Device Model: N56J

OS: Windows 8

When we updated to Windows 8.1 and rebooted the device we noticed that 8 GB of memory was not visible and the NVidia card was no longer on the computer. We have contacted ASUS for support but they just had us roll back to Windows 8.0 and it was working back as normal. Now we got up this morning and it is doing the same thing. We called ASUS back and did a system restore for 3 days back when it was working but that didn't seem to fix the issue. We would be very grateful for any suggestions because when we called ASUS back a 3rd time they told us to contact Newegg where we got the laptop, but we have not called them yet.

A software update doesn't magically remove or alter memory or the graphics card. The only way 8GB of memory could "vanish" would be changing from a 64-bit Windows to a 32-bit version. But that doesn't happen with an update [e.g. to Windows 8.1]. It would require Windows to be reinstalled from scratch which you don't seem to have done?So as far as the memory goes you SHOULD contact Newegg as it might be a hardware issue.As for the graphics card it most likely was just the driver that wasn't working under Windows 8.1. You can always get the latest driver at the following link. Make sure to select the correct series, model and operating system.http://www.nvidia.com/Download/index.aspx?lang=en-us
