I just bought and put together my first computer. All was going well until I tried to boot up, and even that was ok
I'm not sure if I missed something or if it is a motherboard issue, but when I turn on it goes to a boot screen and tells me there is no keyboard detected. My mouse and external DVD Drive are detected, but no keyboard. Both the mouse and drive are USB, where the keyboard is the old connection (not sure of name). I don't know why it isn't being detected, I have tried multiple keyboards with this input style, all to no avail.
If anyone has ideas please pass them on. I don't think there is a connection I missed because that receiver goes straight on the MB.
If it will help here are my system specs:
MB: ASUS M4A78 Plus AM3/AM2+/AM2 AMD 770 ATX AMD Motherboard
Video card: SAPPHIRE 100245L Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card
PSU: OCZ StealthXStream OCZ700SXS 700W ATX12V / EPS12V SLI Ready CrossFire Ready Active PFC Power Supply
CPU: AMD Phenom II X2 550 Black Edition Callisto 3.1GHz Socket AM3 80W Dual-Core Processor Model HDZ550WFGIBOX
Other things you can try:
1) get a PS/2 to USB adaptor (http://bargainhopping.com/cart/images/ps2%20to%20usb%20...) and plug the keyboard in an USB port instead.
2) check if in BIOS the PS/2 support is disabled. I don't think it is, since PS/2 should have native support, and you can usually enable/disable the USB mouse/kb support in BIOS, but it's worth a try.
