So I've been having this issue for ages. I have a Corsair K55 keyboard that won't let the pc boot. I figured that it was because it's an office pc. I recently upgraded every part in the pc, and the keyboard still gets it stuck in BIOs. I know it's the keyboard because every time I unplug it before booting it boots fine. then I can plug it back in when it's past the BIOs, and the keyboard works perfectly. Is there some BIOs setting I need to update?

Edit: It's a Dell Optiplex 790 and the PSU is also Corsair.
