Ok, so I can't test this today I have to get away from the PC for a week for studies, but as soon as I'm back, I'll give all your ideas a try, and will report back the results of each of those tries, so please feel free to fill this thread while I'm away, I'll try every ideas you tell me mates !

Thank you very much,
Hueyman

Hello ICit2lol, how are you today ?

OK, I tried all your methods ( anti malwares etc ) with no luck, but the latest, the Kaspersky Rescue Disc seems to work ...

At least, I'm typing from my " victim " computer with my " victim " keyboard right now under the Rescue Disc operating system right now, with the minimal programs. So there is definitely something wrong when Windows 7 is starting up !

I've launched a full scan now, should take all night long, will get back to you soon !

Thanks,
Hueyman

Sorry really late reply Huey I have been away from home - anyway I am glad something is working.

Another one you can run and I have found good too is the Emsisoft Emergency Kit scanners a mate from here put me on to and it certainly got rid of a lot of rot from my main machine.

https://www.emsisoft.com/en/software/eek/ I found I only had to use the Emergency and Command line scans to sort out my stuff.

Hi ICit2lol mate !

That's fine !

The rescue disc scanned for 15 hours and got stuck at 61% for 3 hours so I cancelled it. At 61% not a single threat was detected, so I ran your last option, Emsisoft, and it's running for 7 hours, 75% now, and 22 threats detected, hope the bad boys are in there !

But I have hard times believeing at the end of the scan, I will reboot and recover my keyboard under Win 7 OS...

I had a question : does Windows can " failsafe " some USB functions when it detected something very unusual ( like over current ) from a USB device ? I ask this because the keyboard stopped responding two weeks ago, exactly when my Joystick got un-connected. As I said in the original message, after opening the joystick, some wires were unsoldered so I conclude a serious overheat ( maybe ) in this device, that may have altered others ( keyboard ... )

Thanks for helping me dude,

Hueyman

Valentin lets see what this last scan comes up with and if it clears a few more problems. now I can't remember asking if you have all your important data backed up if not do so as soon as.

The overload problem I am assuming now would have some overload protection because it makes sense that to have something like that built in.
The worry is of course those unsoldered wires you found and if they have in some way triggered a cascade of problems with the keyboard.

But at least do the back up Imaging with free Macrium

Sorry to butt in at this stage, but if your Joy Stick has unsoldered wires then it is likely there was a heavy short circuit somewhere & this may have damaged the USB components on the motherboard. You may have to get this checked out by someone that understands the circuitry of motherboards & can test it.
Not good news but short circuits usually damage electronics & in a lot of cases, beyond repair.

No mate you are welcome to hop in two heads better than one. The thought did cross my mind a while ago as I did think maybe the power to the USB port had shorted to the data leads as Valentin did say there was message to an over power to USB plus I did say at the time (post #15) that it may have been damage through the keyboard and well I was rather hoping it was an easy fix and not something drastic.
I can't think of any way to test the motherboard as such if there has been any hardware damage then it is easily tried out with the different tests for the hard drive RAM etc

Having said that the power to USB's if I am not mistaken is limited to 5 volts and hopefully has not damaged anything but the plug in devices.

Hi ICit2lol. I agree with you that the USB voltage is limited to about 5 volts, but the fact that his joystick has, what he described as melted solder, or serious overheating, then one would have to assume there has been some serious current flow short circuit across something to cause that.
I don't know what amperage limit there is in a USB circuit but I image it would be pretty low. Perhaps there been a short circuit on the motherboard that reach the USB & the joystick.
I think he will have to get an expert to look at the computer to see if there are any electrical faults or circuit failures.

Yep well I agree that it does need checking out and as for the current in a USB circuit it depends on the type or version of the USB 1.0 2.0 or 3.0 as you can see from this How USB charging works, or how to avoid blowing up your smartphone | ExtremeTech
Given that the "rails" and system components PCB's of any of todays devices are extremely small I would be very suspicious if even 5v @ 0.5A were put through them let alone something over 1A.
Hopefully it hasn't come to that.

Hello guys and thanks for your input.

My fears were more about the fact that the joystick internal PS/2 plug caused some various " software " issues, feedback to the PC's OS and it's way of managing USB devices...

Physically, I don't think anything is damaged as I'm typing right now on the computer, and with the keyboard that was suspicious... I'm just typing from Kaspersky Rescue Disc lightweight integrated Operating System.

The keyboard works flawlessly on the same computer, with the same motherboard...

THE PROBLEM IS : AS SOON AS WINDOWS 7 IS RUNNING, NOTHING WORKS BUT THE FN KEYS

It's as simple as that ( and as frustratingt too !! )

Please guys, please make suggestions of anything that haven't been tried yet. To be clearly aware what have been tried, read carefully the original message, plus some others with ICit2lol ideas. I must add I also tried to shut down the PC, unplug the Power Supply and press the Power button for 50 secs, no success.

The Kaspersky Rescue Disc finally just finished its global system scan, with more than 15 000 000 files deeply scanned. Not a single threat was detected, they were all erased with previous other methods ( anti malware bytes etc ... )

My PC is now factory clean, and still suffer this crazy problem. So yes, please input any other idea you have in mind, just keep in mind this :

Before Win7 OS is running ( BIOS or other OS such Kaspersky Rescue Disc one ) : everything works fine
As soon as Win7 OS is running, all standard keys, everything but the FN Keys aren't working at all
The mouse ( Logitech USB MX 550with Unifying receiver ) and all other USB devices work flawlessly

I'm about to surrender guys ;-(

Thanks,
Hueyman
