Windows 7: Stuck with probably the rarest Win7 keyboard problem ever saw ...

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

Welcome to the forum Mr Iroquois, I recall many years ago with XP a similar problem and I ended up doing a complete fresh install of the OS. It was the only solution I could find. I know that's not what you wanted to hear but it may be the fastest solution in the end.

Possible remove all USB drivers, all keyboard, mouse and joystick drivers, then reinstall them. From your description it certainly sounds like a driver issue. This may help.

in safe mode if you have to and you may need to use Option 2 in chkdsk.

Usually Logitec stuff comes with installation software so did yours?? Take a look at this

Hello guys and thanks for your replies !

I'll consider the restore option later this day when all will be saved on my ext. HDD

I tried three times the method you sent me links to, no success.

@ICit2lol :

Tried these too, no joy either ;-(

Logitech Set Point has nothing to do with, as even my simple MS keyboard doesn't work

Probably the restore will sort me out, but would like to know THE solution, as spending 3 days reinstalling 1200 Go of files, softwares etc is really catastrophic for such a stupid keyboard problem

I'm convinced there is another solution, if only the person who know it could stop here ...

Thanks guys, keep hoping ! It's been 8 days I type with on-screen keyboard, really got mad

I have the feeling there is something terribly wrong in the drivers and HID stuff on my PC, some softs or malware probably put the mess in this fragile environment of drivers etc ( seeing all the new strange devices that appeared recently on the Device Manager ), I can't factory reset the PC for such an issue, it obviously has a solution !

I mean, I use this PC for so much versatile applications, such flight simming, Computer Assisted Music ( Reaper, Pro Tools ), CAD with Solid Works, 3D modeling with Blender, 2D editing/textures with Photoshop CS6 etc

It's truly a work station and re-installing ( and make the settings the way you used to like them ) everything is really a terrible thing ... ( Especially when I had to restore Win7 already three months ago for other Windows related issues )

I don't know if it's worth I hire some local PC technician, that will take me 35€/hour to make the exact same manipulations and trials I already did, but there is obviously someone on this planet who know how to recover the use of my " standard keys " in Windows 7 Pro x64, as it already works as it should in the BIOS, so nothing wrong in the hardware side.

Does the " HOTAS Warthog " issue I described above could be some kind of causes, doesn't this give you ideas on where to investigate ?


I'm not at all a PC expert, but I use a PC since 2004 ( started with XP, then Vista and now Seven ) and encountered countless issues since, like serious graphical issues, hardware conflicts, very bad viruses, total lost of internet connection, registry keys conflict etc ... but I always ended by solving these issues by myself, with the help of the specialized internet community of course.

I can't believe this crazy little keyboard problem will force me to make a hard reset of the whole system ;-(

If some of you guys have time and deep knowledge in this area, this user experienced the same problem I am ( but with a wireless keyboard ), and resolved it like this :

Logitech K360 Wireless keyboard only FN-key combin... - Logitech Forums

I don't think the keyboard brand has much importance in this issue, as every keyboard does that, when something is wrong on the OS side ...


Thank you very much guys !

Huey mate try these

http://www.superantispyware.com/

http://www.malwarebytes.org/products/malwarebytes_free/

http://www.bleepingcomputer.com/download/adwcleaner/
downloadfrom bleeping computer – delete any rubbish these find

If these do not come up with anything try one of these
5 Bootable AntiVirus Rescue CD for Windows: Free Download

the Kaspersky is as good as the rest but you will need to make a bootable disk > set the BIOS to both from either the optical (my preferred way) or a USB stick - again as you are having problems there stay with the optical. The rest I haven't yet tested yet so am not sure how good they are and I run paid for Kaspersky on all my machines anyway.
What this will do is to scan from power on and check literally everything as it starts up.
Now it does take a fair while to run but just may pick some rubbish malware on it's way into the system.

Hum mate that is one strange looking KB I was under the impression the qwerty KB was a standard international set out.

Now for pics try this mate as your way is really very small to see and also lists a lot of pics in a library of yours.
