Hello butchzxc and Welcome to Seven Forums :)


I want to remind you that Laptop manufacturers use their own versions of Graphics Drivers (as their chips are also specialized to that manufacturer's specifications).

Have you tried the latest available driver from the manufacturer of your Laptop?

Thanks for answering @georgeks and @axe0. Ill try downloading updates from toshiba. Hope it fix my problem.

Edit: Is it ok to get updates from different toshiba product? Say ill get from Toshiba L840-BT2N22 but my is L840-A838.

Just to note, we don't know if you edit a post which is why editing is usually not recommended to do
