I have a second hand clevo laptop, its 2 years old and worked fine with the GTX980M preinstalled by the seller. I don't have much knowledge of video cards, bios sadly.
Couple days ago i forgot my bootable windows 7 usb in the laptop and after a restart it booted up. I don't know what it did but it beeped 8 times and shut off. After that i booted up to my Windows 10 hoping it was just a basic driver problem. Nothing changed in the Windows 10 drivers yet it beeped 8 times and shut off. Maybe
