HP Laptop keyboard fails... sporadically

This is a bizarre problem.

HP Laptop HDX9494nr
Vista 64-bit
4g ram

Occasionally/often when using any text-editing application (Word 2007, notepad, email, even my own applications I write) some of the keys will start failing

The '' < , . > / ? keys and probably a couple others. They usually input spaces instead of symbols though the '' key if hit multiple times outputs ' '
Shutting down all instances of the application restores the keyboard to its default, working behavior but the problem will happen again, but its random. Sometimes it is happening every ten minutes othertimes I get away with a full day's work without it popping up.

Any ideas?

(Note: This is using the keyboard laptop AND/OR a seperate wireless keyboard)

    I figured out what the problem was.

    For some reason pressing ctrl+shift toggles between different language settings. It was changing my keyboard to another language scheme.

    To fix the problem I just have to press ctrl+shift a couple times and the keyboard starts functioning properly

I suspect your problem may be caused by the wireless keyboard, even if you are not using it. You may be using your computer in a "noisy" environment where the wireless transceiver is picking up random signals and corrupting the keyboard interface. Or the wireless keyboard driver could also be at fault.

Can you de-install the wireless keyboard from your system and see if the problem occurs again?

NOTE: I had weird problems with my Microsoft wireless mouse until MS came out with an updated driver for it.

32bit vista to 64bit win7

your recovery manager files should be on drive D or other partition. if not then its gone. but the operating system cd that goes with your laptop is still better than the factory default anyway but the thing is, youll need the cd everytime you want to reformat.

if i where you, il go for 32bit win 7 since your computer used to be a 32 bit vista. no worries about making the most out of your computer since win 7 eats less than vista anyway. and go for 32 bit since your laptop is made for 32 bit.

Cust is not able to download any program on vista operating system it gives an error message as not supported on windows 64 bit

there is very little software, and virtually no freeware, that supports vista 64 bit. return the computer if u can and exchange it for one with vista 32 bit, these machines usually have 3 gigs or less of ram, where as the vista 64 bit systems will typically have 4 or more gigs of ram.
