Yeah you entered UEFI BIOSIt sounds just like on the video you linked, Fedris,
Now my PC is out of the room and I can somewhat cope with the noise it makes, I decided to use it as I would normally.
I was playing a game earlier today and my monitor turned itself off, after around 5 seconds it turned back on and windows informed me that "Nvidia Kernal Drivers failed but sucessfully restarted, assuming it was a driver problem, I went to Geforce Experience and began reinstalling my drivers.
I know from past experiences that when installing GPU drivers, the screen can sometimes flicker or go off for a while, so I wasn't so concerned when it did as I started to install the drivers. After 5 minutes or so however, the screen was still blank and seemingly not coming on. Usually, the drivers only take around a minite to install.
With no solution in sight, I turned off the PC using the button on the case and restarted it and was greeted by an unfamiliar menu that said "American Megatrends" and listed my RAM and CPU and gave me numerous options such as "performance" and "balanced". I clicked on "Save and quit" as I have absolutely no idea what this menu is or what I'm doing with it and windows started to boot and the drivers have apparently installed finely.
I'm doing another scan with malwarebytes before I attempt to start another game. Anyone got any insight into what the hell just happenned?
If it's only happening with games and such then the noise is most likely coil whine, I have the same problem, it's annoying as hell when I don't have my headset on and I sympathize with you. Only solution really is buying new components one by one to try and get rid of it :S
