I have a computer that is running XP and a couple of days ago it started to type **************** all across whatever program you have open that will accept text, including the command prompt. No new software or hardware has been installed on this computer in more than a year and all updates are installed. When this started I changed the keyboard and that didn't help, I then unplugged every device except for the keyboard, mouse and monitor and it still does it. I have ran AVG and Malwarebytes and they find nothing on this computer. I am running out of ideas and am hoping that you can help.
It is so random that I haven't worked with it in safe mode for any length of time. During the time I was running AVG and Malwarebytes in safe mode it didn't but I'm not sure that really tells me anything. This happens every day for that last week, some days it will happen once during the course of about 8 hours and on other days it happens 20 times or more. I will try and uninstall the keyboard and see what happens.
The keyboard is wired. I was originally getting sixes across the screen so I replaced a usb keyboard with a brand new HP ps2 keyboard and now get the asterisk across the screen. If when it is doing this I hit the 8 key then it will insert the 8 and go right back to ***
Well that was a good place to start but after a couple of hours it has started again. Any other ideas would be greatly appreciated. It does have a wireless mouse, could that have anything to do with it?
I had already checked this computer for Malware and it was clean, that was my first thought. What I ended up doing is replacing this computer with another one that I had, once I did that I fired it up with all of the same peripherals that were on the old one and within minutes it did the same thing. With that I knew it wasn't the computer and there were only two things that had not been replaced or removed, the wireless mouse and the monitor. As strange as it is, it looks like it was the wireless mouse that was causing the problem, I put a ps2 mouse on and have not had the issue again and it's been a week.
