Maximum PC

I just upgraded my computer and sometimes when I boot up, the keyboard isn't recognized. If I unplug it and then plug it back in (even if it's the same port) it works again. I've also tried other USB slots and it does the same thing. Here is my build

CPU: Intel Core i5 3570k
Motherboard: MSI Z77-G45
RAM G.Skill Ripjaw Series 16GB DDR3 1600
Video Card: EVGA GeForce GTX 670 SC
OS: Windows 7 HP
Keyboard: Microsoft Natural Ergonomic Keyboard 4000
I also have 3 hard drives and an optical drive (of course).

OK, so it looks like I have the latest BIOS. I'm not surprised because I didn't even get this from Newegg until last week. Any help would be appreciated!

I know it's not the keyboard because I was using it in my last build not 2 two days ago and that never happened.

**EDIT** Added keyboard

You didn't mention the keyboard.

I added the keyboard..

Microsoft Natural Ergonomic Keyboard 4000 Keyboard

Have you installed the latest drivers for the keyboard? Also you are not using the keyboard on the USB 3.0 slots are you?

I believe I have the latest drivers but I will check to make sure and no I'm not using it on the USB 3.0 slot. Why would that do anything if I were though? USB 3.0 is backward compatible, isn't it?

**EDIT**

I checked and I am using the latest driver for the keyboard. The only other thing I can think of is maybe it's the BIOS? I currently have the latest BIOS, but when they update, I think I should get it.

Legacy USB enabled in bios?

Yes it is...could that be the problem? Should I disable it?

While it is backwards compatible, it is not natively supported in Win7, and requires a driver. That is why I asked if it was in a 3.0 slot, you would have to wait for Windows to load the USB 3.0 driver before the keyboard would work. I ran into this with a case mod that I was doing, I had a thumb drive and a keyboard in the 3.0 slots, and windows would freak out trying to install, figured that part out, then plugged the keyboard back into the 3.0 slot and I could not log into windows. Plugged back into the 2.0 and it would work, once the 3.0 drivers were install the problem went away completely.

Sounds to me like its not a BIOS issue, as the keyboard is working in the BIOS section, it sounds like a corrupted driver install, as when you plug the keyboard back in it works, that indicated windows is reinitializing the driver. Does it do the same in all the slots? If you are running off the front ports try a mobo hard wired port. Also you are not using an add in card to run the keyboard are you?

::EDIT::

Which board do you have, that is not a valid model number, it will be a Z77MA-G45 or Z77A-G45, and they both have BIOS updates, the Z77A had one released on 5-9-12?

OK, sorry my fault, I wasn't clear. When the keyboard is not working, it is also unresponsive to getting into the BIOS too, so nothing works at any point (when it's giving me problems). It's been a couple days and so far it's been fine. I'm hoping it's OK....still not sure what the problem is/was because I did nothing different. I'm thinking it is BIOS related since it's doing this at the very beginning. I wish there was a BIOS update cause I'd definitively do that. Oh and the mobo is a MSI Z77A-G45 http://msi.com/product/mb/Z77A-G45.html

Are you sure that you have the 2.4 Bios revision? I ask because you posted this on the 17th, and said you had the board for a week, that would make it around the 10th that you bought it. The supply chain being what it is, I don't think it would be enough time to get a board with the latest BIOS on it.

You sir are correct! When I first posted this, the newest BIOS update was 4/12/12 and the new update is listed as 5/9/12. Now having said that I haven't had any more incidents in 3 days now so unless it happens again, I'm not going to update the BIOS. Thanks for pointing that out!
