Bought all the ingrediants for a new system. Put it all together late last week, powered it up to begin install of OS system. It would shut down fairly quickly after start up. Hit the "delete" key to bring up BIOS on screen to check temp of CPU, which was out of control. Key here is the keyboard worked.
Then purchased some additional motherboard fans and new CPU fan from newegg. They arrived yesterday, installed them, powered up system and it did not shut down, however i noticed keyboard was not working. Tried another keyboard and plugged it in. This one didn't work. Keyboards will not work in any USB port. Both of these keyboards work in other computers. Plugged a mouse into same USB port. It worked. Just completely baffled. Any help will be appreciated.

Hi there, welcome

I suggest you try a PS/2 keyboard, to see if that works. It sounds like USB support got disabled in the BIOS, which would then account for the USB keyboard no longer being recognised.

How can you test that the mouse works? Do you have a working OS?

Thanks Troy. This is actually my son's. He is away at college. He said the mouse lit up when he plugged it in. No operating OS yet. He is going to try the PS/2 keyboard and see if that works.

The mouse lights up is a sign it's getting power of some sort - it still may not work either...

In that regard, do the keyboard lights come on at all (num-lock, caps-lock, scroll-lock)?
