Hey guys hows it goin? I have a question that i cant seem to fig. out. I bought a new barebone for my desktop. (it comes with a new power supply and fan.) i used the same hardware in the old one and moved it into the new barebone. Everything works, windows loads properly etc.. except for 2 things. The mouse and keyboard do not work, they dont seem to even turn on. The problem may be b/c of the new wiring, but there are no special cords/cables running into the PS/2 and keyboard ports.
if someone could please help me with this, i would GREATLY appreciate it.

*note* im writing this message on a differnet computer

thanx

Short, hardware-focused addendum that expands on the replies from and with tests and checks not yet covered.

Start with device isolation. Confirm each peripheral works on a known-good system (or try a different known-good keyboard/mouse on the barebone). A totally unlit keyboard/mouse usually means the 5V supply to those ports (PS/2 or USB VBUS) is missing rather than a Windows driver issue.

Recommended diagnostic sequence:

  1. Boot with a minimal configuration (motherboard + CPU + one RAM stick, no drives or PCI cards) and use the rear I/O ports only. This separates front-panel wiring or add-on cards from the core board.
  2. Visually inspect PS/2 ports for bent pins and the rear I/O for loose/damaged solder or a separate daughterboard — some barebones route I/O through a small daughterboard or require an internal adapter cable. Consult the barebone manual for required internal cables.
  3. Check front-panel and internal header connections: front USB/PS/2 ports are often wired via a header/cable that can be mis-seated or omitted when moving components to a different case/barebone.
  4. If comfortable with basic electrical checks, verify +5V on a USB VBUS (or on the motherboard front-panel header) with a multimeter. Observe safety: power the PC, probe between VBUS and ground, avoid shorting pins. If unsure, skip this step.
  5. Reset CMOS (clear CMOS with jumper or remove the battery briefly) to rule out configuration-level disabling that survives a normal reboot.

Likely interpretations and next steps: if ports show no 5V the problem is PSU/motherboard wiring or a missing internal cable and not Windows. If rear ports are live but front ones are dead, focus on the internal header/cable. If all ports are dead but PSU rails are present, the I/O controller on the motherboard or the barebone's I/O board may be faulty; a low-cost USB PCI card (or a powered USB hub for testing) can be a practical workaround while sourcing a replacement board.

look in the BIOS to see if anything is turned off(PS/2 wise) and make sure the keyboard and mouse are plugged into the right plugins(you could have switched them) or just switch them to see if it works.
