Stuck with probably the rarest Win7 keyboard problem ever saw ...
Hello everyone,
I'm new on this forum, you are my last chance before placing some TNT in the heart of my machine
Ok, so I'll try to explain as good as I can my problem. I'm French and please excuse me for my bad English, thanks.
My keyboard do not work anymore for one week today. It is a Logitech K740 Illuminated Keyboard. It suddenly stopped working during I was using the PC. The symptoms are :
Every standard keys ( A,B,C...1,2,3 ... ) are not working
Every FN Function keys are working flawlessly
I did everything I had in mine on the first day, one week ago :
- In the device manager, I uninstalled EVERY USB drivers of EVERY devices I had, then I unplugged them
- Uninstalling of old ASMEDIA MoBo drivers and updating with new Asmedia USB3.0 Controller Driver V1.16.10.0 for Windows XP/Vista/7 32bit & 64bit.(WHQL)
- Reboot of Windows in " Clean Mode "
- Re-plugging of mouse and keyboard only
- Installation of latest drivers for mouse and keyboard
- Tried every USB ports ( 2.0 and 3.0 ) on the Mother Board, as well as front USB ports
- BIOS Update latest version ( 4804 )
- Windows Update updates
- Bit Defender Total Security Full scan
All this without the slightest success.
The keyboard works flawlessly in this computer BIOS and in another computer ( and old small laptop with WinXP on it, which I'm typing from right now )
So it became clear it was a software/drivers/OS/HID conflicts right now.
So I called Microsoft here in France, and I had the hardest times trying to explain them it has nothing to do with the " physical " keyboard... but they didn't helped cause I had a Logitech keyboard. After a long call with Logitech support people ( nice people BTW ), it was even clearer that the issue was in the software side, so I took the cheapest Microsoft keyboard, just to make them happy, and called back Microsoft. One of their technician took control of my PC remotely and during 2h and a half, tried many things, all of them failed. They said they would call me back today but they never did.
This is why I hope you guys are true Windows gurus, with deep knowledge of how things works together, in order to help me. I'm using the Windows built-in on screen keyboard, which is really a pain in the rear.
The fact that only the FN Keys ( like launching the music player, play/pause, next song etc ) works and not the " Standard " functions is really weird. I already saw that kind of issues over the forums, but only for Wireless keyboards, never for wired ones !
The ONLY weird things that happened, almost exactly when the keyboard stopped functioning, is related to another device :
The Thrustmaster HOTAS Warthog, a two parts Joystick assembly ( Throttle + Stick ) that is independently connected on the PC, then virtually " merged " via a software ( called " T.A.R.G.E.T ) for the OS recognize is as a single USB device. It stopped working, disconnected and more or less 5 min ( after or before can't remember ), the keyboard stopped working too.
After further investigations, I saw that inside the Joystick, 4 wires out of the 6 of an internal PS/2 connection got unsoldered ... This is why I made some crazy theories like " There was a general overheat in the circuit that feedbacks some bad things back to the PC ... " and things like that.
But nothing is physically or " hardwarly " damaged, as both ( Logitech and Microsoft ) keyboards works OK in the BIOS, but not once the OS is running ( even in safe mode )
My last cartridge was to restore Windows 7 back to a point everything was fine, but strangely, there was none prior to this date, the 21st of March
So, I'm desperate guys, you are my last hope before attempting to blow up the PC, typing with the on-screen keyboard for one week is really a hard experience lol,
My best regards,
Valentin
