CTRL Key Blocked

Is the keyboard key stuck? You mean it's pressed down and you can't lift it? If so, take a screwdriver or something similar and lever it to unstick it.

If it's stuck due to software issues, then start by rebooting and we'll see from there.

Is it a desktop or a laptop??
If it's a desktop, take it apart.

To answer you kyuusei, the key is not stuck at the hardware level because I blew into it, I tried to lift it with a screwdriver but it remains stuck at the 'software level' as you say. I tried rebooting and the worst part is that I can't even format and reinstall Windows because it asks for the Windows key and since the keyboard doesn't work I can't even enter it. And to answer the other question, it's a laptop, I tried pressing all the keys, doing the 'brute force' but nothing works, the problem persists.
I actually managed to get it to work 'SORT OF' normally at one point. I typed 'help' in paint and then when I opened notepad the keyboard was working but all the keys were reversed.. BUT it was working. I want to point out that the PC has no antivirus.. =(
Thank you for your responses..
I’m waiting for more =P

Well, first, All programs > accessories > accessibility tools > on-screen keyboard, it will allow you to have a fake keyboard but at least you can do a few things with it.

Then download Ad-Aware or Avast and run a scan of your PC, and remove the viruses, at least that will eliminate 99% of the chances that it's due to a virus if it doesn’t work.

Good evening, the on-screen keyboard in XP is not working, the problem is the same, I have already tried.
Neither the on-screen keyboard, nor a USB keyboard, nor the laptop keyboard, nor a keyboard with a 'round' purple connector... (sorry for the name of the connector). Thank you for your responses, I am looking forward to more =P. I will try Ad-Aware.

Hmm, that's really weird.

I can understand that none of the external/internal devices are working, but for the on-screen keyboard to bug, that's impressive.

Is it only messing up in Word?

No, I can't write on Notepad, neither on the internet nor on Paint, nor rename files.. I can't even enter a Windows activation key during formatting + reinstallation.. Depressing.. I'm trying a scan with AVAST.

It's strange..

Because I can understand the on-screen keyboard bugging under Windows or something
So it's a software problem

But that it bugs during a reinstallation

Wait, I just had a thought, could it be coming from the BIOS?, because right now that's all I see

Ps: unless it's a dual software and hardware problem

I just ran a scan with Avast, and after a restart, the problem persists. It's not hardware-related because all the keys work; well, since CTRL is held down when I press P, for example, it executes the operation 'CTRL + P', which means print. So it's not a hardware issue. I will check the BIOS tomorrow; for now, I'm running a more thorough scan. I'll see tomorrow. I'll keep you updated. Thank you very much.

In my opinion, it's a hardware issue, let me explain

I think the ctrl key is indeed stuck, even if it's not pressed, something must be making contact and forcing it to activate.
This means that even the on-screen keyboard doesn't work anymore, and the same happens during a Windows installation

And you don't know how I could fix them? =( I really need this keyboard =(
And I don't really feel like taking the PC apart ..
Is the only solution to take it in for repairs?

To 'resolve' the problem, finally, to make the computer usable while finding a solution:

You should plug in a second keyboard in the meantime

Otherwise, I was in class today and I thought about your problem (because technical drawing, phew.) but nothing came to mind, there are utilities that allow you to disable ctrl+alt+del but I don't know if there are any that can remove a key

I just removed the CTRL keys (the two on each side of the space bar) and apart from two small hairs and a tiny breadcrumb, nothing is pressing on the latter.. Computer issues can be really incomprehensible sometimes!
I really want answers to everything; it's quite annoying, especially since I can't even uninstall the keyboard. I tried uninstalling it via the device manager, but it doesn't work!
The two CTRL keys are off... I'm hesitant to open the computer =( ..
If anyone has a solution (L), I'm all ears!
Thanks..

Martin.

Thank you, kyuusei, for thinking about my problem in class. I tried connecting a second keyboard, but unfortunately, nothing works.
I searched for how to disable some keys, but it seems complex. I definitely don't want to get myself into impossible manipulations.

After two Avast scans, a boot in safe mode, and manipulations with the SHIFT key, nothing works, still the same problem..
I am waiting for responses =(

My problem is solved, I did a registry cleanup with Ccleaner, my keyboard is working again, I was able to format! Thanks everyone..

Hello, my little contribution:

I have an HP laptop, I am careful and so I have never spilled any liquid on the keyboard, and the key is not physically stuck, but sometimes, after playing certain games, I find myself with the control function locked.

(impossible to type, it gets "stuck," since the control function is activated, everything turns into shortcuts.)

I also want to clarify that it is not related to any wrongly checked option in the Ergonomics category.

The only two "workarounds" found so far are rebooting and using the virtual keyboard (Ctrl + Shift then release, but tends to recur with this second method).

Hum hum I don't know what to say:
1- try to back up your entire computer + system image
2- run the rogue killer and ccleaner scans
3- upgrade to Windows 7 for example
(I think your system is unstable and needs to be restored)

Hello! I would like to add my own solution: after trying everything (driver update, antivirus, on-screen keyboard...), I discovered that my problem was not actually related to the keyboard but... to my mouse!!

Among the many buttons on it, I had a Ctrl button that was simply stuck... Cleaning my mouse helped me resolve the issue!
