Hello again, I've got a customer with what sounds like a memory issue. I want to run Memtest86+ on it, but there is an issue. On bootup, I get "keyboard failure" and I can't enter the BIOS to change the boot device priority so that I can load Memtest86+ from a flash drive or cd. The keyboard works fine once I'm into Windows, but I can't use it before Windows loads. Things tried: Reset CMOS. Unplugged all other usb devices, including card reader internally. Checked device manager, looks clean. Thanks for any help.
