I am having some strange keyboard issues. When I turn on the system I am able to get into the BIOS using the keyboard, however about every other time I boot the keyboard is not detected during startup when the keyboard is detected it only works long enough for me to type in my password and hit enter after which the keyboard is unresponsive. I am using a usb keyboard and a usb mouse the mouse has no problems. I have switched keyboards hoping that was the problem, but no luck. Unfortunately I don't have a ps2 keyboard to try at the moment to see if the usb is the problem.

I am running Vista Ultimate 32bit version, on an Asus Maximus Formula motherboard. I would greatly appreciate any help provided.

When I've run into that problem it was a mobo/USB issue that required a PS2 keyboard to get into the OS or BIOS. With that mobo it sounds like a USB issue. I keep a PS2 keyboard on hand just for that situation. By the way, where are you located? I could use a laugh.

If usb is the problem, u can get a ps2 adapter for cheap so u can still use that keyboard.

Thanks for all the ideas. So far I have tried a usb/ps2 adapter which was fruitless, as well as a ps2 keyboard. So far no dice letting my use the machine. Unless anyone has a better suggestion I am going to try to RMA the board.

As to where I am located, until recently I was located in a place called Goodwell, which ironically is neither full or good wells or water. I find it to be quite hilarious myself.

Is USB legacy support on?

I double checked to make sure USB Legacy support was on. It was set to auto, thinking maybe that was the problem I set it to on saved and rebooted. Still this did not fix the problem. I did finally notice though that the keyboard seems to be working until part of the way through the Vista boot.

I was able to use the ease of use features to turn on the on screen keyboard so that I could check the device manager. The keyboard shows up as an unknown device, I tried uninstalling it an rebooting the machine. Doing that allowed me to use the keyboard for a short while, until vista decided to install the drivers for it. After vista did its driver thing the keyboard quit working.

Thinking that vista was using either a corrupt or missing driver for the keyboard I tried to tell vista where to look for the driver. I told vista to look in the usual system 32 folder for the driver, it tries to use the ps2 keyboard driver even though the keyboard is usb?

At this point I have no idea what would be causing this? Any Ideas?

Dude, you've been having weird problems with that mobo since the day you got it. You should just RMA it and get it over with.

Also go into the BIOS and make sure that the keyboard and mouse are not using shared IRQ's. I've seen this problem before and that was the issue.

Well I decided to give it one more shot before I RMA'd the board. In the device manager I noticed that it was trying to use a ps/2 keyboard instead of USB. I uninstalled that and scanned for new devices, instead of coming up as a usb keyboard it still came up as a ps/2. Thinking that was very strange I started digging around in device manager and noticed that my usb mouse was listed twice, once under mice, and once under usb devices. However the keyboard only showed up under usb devices but not as a keyboard it was listed as an unknown human interface device. I uninstalled it from there and scanned for new devices. For whatever reason this seems to have fixed my problem. I guess this is just a case of vista being strange.
