Power on your laptop and press either F8 or F12 for Del to access your BIOS. I am not sure which button it will be to access your BIOS but it should tell you on the screen when the machine is booting. Once in the BIOS, look for BIOS 'default' settings or 'Restore Default seetings' or simalr. Once your BIOS is reset, see if it makes any difference.
If no change, we can investigate further. It would be handy to have the exact make and model of your machine, please provide spec and model info. Thanks.
Second time responding here, first one didn't post, It is a Gateway M Series Model No. SA1. Hope this help. I really appreciate your input.
