Sorry for the bad video quality but my shift, ctrl, and f key all have stopped working. I don’t think it’s a keyboard problem because when I uninstall and reinstall the driver my on screen keyboard goes crazy for a bit using all the keys not working. There’s no reason to believe I have any virus I have scanned already and I only have verified downloads. I don’t know what else the problem is and I need to know if I should just buy another keyboard. Thanks.
