I have a Gateway Desktop DX4860 with a Dell 17" flat screen monitor. When I try to boot from a flash drive I get the following message: "Can not display this video mode" this only happens when booting from a flash drive. I have created a number of bootable flash drives and all of them give me this result. Some of the flash drives are over two years old and have been working but are not.
I have tried different USB ports and different flash drives. I have checked, deleted and let windows reinstall the driver still won't work.
