|As I've already said:|
"You do not need to load drivers for the standard keyboard, or many other keyboards -they are already in Windows, all the time."
What part of that do you not understand?
Even if you did have an oddball keyboard, which you don't, that required drivers not normally in Windows on the C drive but are on the Windows CD, Laptops if they still have the original software brand name builders installation on them have the entire contents of the Windows CD available to them, either on the C drive, or by background automatic access to the CD contents on the other partition on the hard drive, often called the Recovery partition, whether you can see that partition in Windows or not.
Going by your last post, your problem either has to be your keyboard is no good, or your Windows installation is badly corrupted, or, unlikely, there is something seriously wrong with other laptop hardware.
Does your built in keyboard work before Windows loads? As in, are you able to get onto the bios Setup while booting?
If it does, that doesn't prove the keyboard is working 100%, but it might indicate something in your Windows installation is badly corrupted - if it is a file or files, using System Restore to go back to a previous registry won't help.
In that case
check your hard drive.
See the latter part of response 1 in this:
If you don't have a floppy drive, you can get a CD image of the diagnostic utility from most hard drive manufacturer's web sites.
If your hard drive is fine, you may need to try some other things to see if you can fix files that are corrupted - we can tell you how to do that.
If the keyboard is not working properly, just as with hardware conflicts, Windows may not recognize it properly, or be able to determine whether it has the right drivers for it.
Try it without the built in keyboard connected and a PS/2 connected keyboard connected to the PS/2 port. You may also have to disable the built in keyboard in the bios, or enable an external keyboard, but there may be no setting for that.
If you don't have a PS/2 connected keyboard, borrow one from someone you know, or go to their place and try one; or buy one - they can be very cheap.
If the error goes away with the external keyboard connected the built in keyboard is probably no good.
If it does not go away, either your
If you get the error with the built in keyboard disconnected, and no external keyboard attached, and there are no settings in the bios that would affect that, there are probably serious problem with your laptop hardware.
If the built in keyboard seems to be defective and you want to further check it out, or if all else fails to point to anything in particular, take it to a laptop repair place and have them diagnose it.
