Hello
First of all thanks for reading this post.
I am having a problem with my keyboard.
Both the Ctrl keys of my keyboard has stopped responding. I also think F5 key is not working.
I cannot say with certainty when it stopped working,but I detected it while playing a CD game that I have played many times before without any glitches.

It may be a keyboard problem but what strikes me is that if it is a hardware problem why did both the Ctrl keys stopped working simultaneously???

I also haven't opened or cleaned this keyboard recently.Also another keyboard is not easily accessible to me so I haven't replaced it and checked.

I uninstalled the keyboard driver and rebooted and next time Windows automatically reinstalled the keyboard driver,but this didn't solve the problem.
I have also unticked all stickey key/toggle ket etc options from control panel.

SPECIFICATIONS

OS - XP
keyboard - Standard 101/102-Key or Microsoft Natural PS/2 Keyboard.

What can I do??? Please help.

Hello anirban,

Have you checked the keyboard settings and regional and language settings in control panel for keyboard layout options.
Regards,

Alan.

Hello
Thanks for the prompt reply.
Yes I have been to control panel->keyboard properties,it has two parts speed and hardware.
I donot find any problem there.
The device status given is:

This device is working properly.

If you are having problems with this device, click Troubleshoot to start the troubleshooter.

I haven't tampered with the regional and language settings so should it be a problem,even if it is what exactly do I need to do with it???

If you open the regional settings options and open the languages tab click the details tab and make sure the keyboard is set as English UK

Also you could try opening a notepad file and see if other keys don't work.
Regards,

Alan.

I know you said in a previous post that you mentioned that another keyboard is not easily accessible, but you should check the other keyboard. If it works then your keyboard is broken, if it doesn't there is a deeper problem in windows.

Alan.

Yes ,I think I would have to arrange another keyboard,if I can ,test it and then get back here in 2-3 days time.

But what stops me from thinking that it is a hardware problem is that why would both the Ctrl keys stop working simultaneously????Any reasons there??

Anyways thanks again for the advice.

No problem, glad to help.

I would suspect a driver problem, but as you have re installed them I doubt that's the problem. The keyboard may not be st up correctly, but as you have said in the regional settings it looks ok. It may be a virus infection, hardware fault, or software fault.
Regards,

Alan.

Hi
I borrowed another keyboard from a friend and tested it.The other keyboard worked fine.
So I suspected that it was a keyboard problem.I pulled out the CTRL KEYS of my KB and cleaned and reinserted them.
Next I took my keyboard and tested on my friend's machine and surprise ,THE CTRL KEYS worked properly.I tried CTrl+a,Ctrl+c/v/z/x,ctrl+alt+del all worked!!!!!!

Now when I brought back my keyboard and attached to my computer,IT WORKED FINE,THE CTRL KEYS worked properly.I tried CTrl+a,Ctrl+c/v/z/x,ctrl+alt+del all worked again!!!!!!

Now if that was not to be the last twist,suddenly the computer hanged.I rebooted and keyboard again worked properly!! but after some time THE CTRL KEYS AGAIN STOPPED WORKING and I am back to square one!!!!!!!!!!!!!!.

pls help.Also I would like to mention here that for quite a few days now,I have been getting the BLUE SCREEN ,the errors are random like IRQL_NOT_LESS_OR EQUAL,PFNLIST_CORRUPT,DRIVERIRQL_NOT_LESS_OR_EQUAL etc.Some times the files identified are win32k.sys or atidvag.sys or fastfat.sys etc.It also says some of my drivers may be outdated and some I feel are, since I am using this machine for around 4 yrs. though this may be completely

Pls. help :thumbsup:

This is beginning to sound like a system fault. have you looked in the event viewer? How To Use Event Viewer it may help finding out what is wrong.

Hello
Thanks a lot again for the help.
I have seen the post,but I found that my system time was incorrect so I couldnot determine the time when the system crashed.Next time it crashes,I would try to find the cause in the event viewer.
I have also written a detailed post on the blue screen problem I am facing in the forum on internal hardware.
Pls take a look at the post

No problem, I'll have a look at the other topic. Let us know what you find in the event viewer.
