USB wireless keyboard typing wrong characters

I got a Microsoft Wireless Comfort Keyboard 4000. It has been working fine up until I wanted to format my PC.

The moment I put in my Windows XP Professional CD to format the computer, the wrong characters are being inputted, for example I press "w" and "r" is the character pressed. Every button is mixed up. So I had to plug in an old PS/2 keyboard to get the job done. The problem now arises even before Start Up and in DOS everything.

the PS/2 keyboard works fine, and I used that to format and set up my fresh copy of Windows XP. After everything was running I thought that maybe Windows would detect new drivers that will solve the problem, didnt work. I installed the latest Microsoft Intellitype software/drivers didnt work.

After browsing the net everyone has been saying its got something to do with Regional Options..

my settings are:

Regional Options Tab
English(Australia) - Measurement System set to Metric
Location: Australia

Languages Tab
English (Australia) - US

Advanced Tab
English(Australia)


The most stupidest problem I have ever encountered in my Life and I cant figure it out please help me someone. *** is driving me crazy.

i just tried it on another PC and the same problem occurs.

i figured out the problem, it was the signal from the wireless keyboard to the reciever. Apprently the signal was not turned on properly, after pressing the connect button the wireless keyboard it worked normal again.
