need help, so I just upgrade my motherboard to ASUS MAXIMUS VII FORMULA, every time I connect my USB KEYBOARD cable to back USB motherboards port, when booting its always get Q-Code 64. (Mechanical Keyboard Optical Blue Switch - SADES GROZA)
No AO, stuck on ROG LOGO
but if I disconnect the keyboard USB, it cause warning, "keyboard not found, press F1 to continue" #LOL
and if I use my old rusty keyboard, it run smoothly. no 64 error and direct to windows logon screen.
if I'm connect the keyboard when PC already on windows desktop, it run very well no issue. "BUT"
if I restart the PC and it have to boot, it stuck on error code 64 again.
