Sounds plausible, but how do I go into the bios?
When you start the computer or did a reset you usually see a black screen with some grey text in it (if you see a fullscreen logo or something alike then this is a manufaturer's page to keep the nontechies away from the innards).
The BIOS (
Basic Input/Output System) then performs the POST (
Power On Self Test) which checks the BIOS checksum, RAM, the drives, attached keyboard, etc.
Normally there is a phrase like "Press F1 to enter BIOS". The key to press is usually F1, F2, DEL or something alike. This depends on the BIOS manufaturer, but the key you need to press is told to you. Now, press the key when the phase appears and before the installed OS (
Operating System) linke Windows/Linux/etc. boots.
This will bring you into the BIOS settings. Here you can change many things that configure your rig, like time and date, installed drives, boot order, onboard controllers like Floppy/
PATA/
SATA/
COM/
LPT/
USB/onboard sound/onboard GPU/etc. as far as memory timings, bus speeds, CPU functions like
CNQ, etc.
Find the key you want to change, set it to the desired value and exit the BIOS via "Save and Quit". This reboots your computer and activates your changes.
