Windows 7 can´t find a simple "USB keyboard" driver  

Hi all,

first, sorry for my english, my spanish is pretty better.
I´m having a weird problem, hope you guys can light me.

PC: windows 7 x64

When I was happy

2 days ago, while playing a game, a nice and cold beer dropped over my keyboard, a simple USB one, so I decided to replace it for another one.

I´m a really simple keyboards fan, so I took another USB 15€ keyboard, a Logitech K200.

The problem

I plugged my cheap and simple new keyboard, but windows can´t find any....
Of course, Logitech doesn´t have scpecific drivers, you have to get those microsoft ones.
Well, I tried to use my old and full of beer keyboard even if some keys dosnt work, but, surprise....windows can´t find those drivers...same ones I guess.

What I tried before posting this

I tried all this and nothing get positive results:

-I plugged both keyboards into another computer with windows 7 x32: drivers found and both working.
-I plugged other devices: Windows finds drivers and automatically install them (pen drives and hard drives)
-Tried a system restore: I get a 0x80071a90 error and can´t get it.
-Both keyboards works into BIOS. Once Windows start up they dosn´t.

Hope someone can help me.
Thnak you

Thx for your help.
I already tried that, the problem is windows never can find a proper driver. I noticed that unistalling keyboard and rebooting, the keyboard works for some seconds, until I get that "can´t find any driver" message from windows.
I "disabled automatic update driver" option, but doesn´t work
I bet a dinner that my usb keyboard driver is corrupted...

USB Driver - General Fix for Problems

It is kind of weird that it works in your BIOS but not in windows 7.

If you find the keyboard in Device manager with a yellow triangle next to it then the hardware is recognized but the driver is missing or damaged.

Hey, thx both for your support.

That´s exactly what I get, a yellow triangle. I´ve uninstall, reboot and "Found New Hardware Wizard" around 8 times now: never find a driver.
That´s why I guess driver is damaged.
Also I don´t see any repair option.

Any way to repair that driver or even download a generic one?

I will try that "General fix for USB driver problems"

Durruti, try Fixio Driver Finder. It is as easy as 123.
It can determine your system, it will search for any missing drivers in your system, and install it.

I have the exact same situation, and have concluded, after extensive Googling that this is actually an unacknowledged Windows issue. Windows reaches a point where it gets "confused" in attempting to identify a device, and once that occurs, that's all she wrote. PLEASE CORRECT ME IF YOU ACTUALLY KNOW BETTER. Idle speculation or theoretical solutions are not needed. I have a WIFI Mouse/KB that worked. Over time my USB drivers/ports started acting more and more erratic. I tried plugging in a Chinese SD card reader - it not only didn't work, it also "bumped" the WIFI mouse/kb driver set(more than one driver), and it's been that way despite my best efforts.
