Strange behavior: cursor moves itself, buttons activate themselves

[Jamie Melhuish]

Hi all,

I have a very strange problem for which I have not found a solution to online. I have a home-built Asus desktop (spec below) that has had some behavioral problems almost from day 1 (I've had this computer for nearly 2 years).

1. The first thing I noticed was that sometimes when clicking and holding on the title bar of an application, the application window starts moving (by itself) towards the right. You can mimic this behavior if you click and hold the mouse button on a window title bar, then press the right arrow on your keyboard. See video here (poor capture quality, the window 'jumps' in the video, but is smooth in real life).

2. Next behavior noticed was when using irfanview in slideshow mode, requiring a key press to advance each slide, but suddenly the slides start advancing by themselves in rapid succession (maybe 10 to 20 slides per second).

3. Then I started having problems with dialog boxes, the buttons would flash as if they were being activated in some way. When I clicked on a drop down menu, no matter which item I selected, something would drive the focus down to the very last item in the menu. Dialogs that required administrator privilege (like installing software) often refuse to accept button clicks, with the buttons flashing back and forth (as if the tab key were being very rapidly pressed). See video here:

4. The cursor sometimes drives itself to the right side of the screen. See video here:

5. Once the cursor drove itself to the left side of the password entry field when logging into the computer. I couldn't figure out why my password was failing, until I noticed that after every character, the cursor jumped left (to the start of the password). So I typed the password in BACKWARDS and was able to log on.

I have tried using the built-in graphics card as well as the NVIDIA graphics card, no change. Tried switching input devices. I was using a cheap wireless keyboard/mouse, tried Microsoft USB keyboard and USB mouse, same result.

This problem is repeatable, especially on installation of software (I basically cannot install anything). Who can give me some debugging and diagnosis tips?

Thanks!
Jamie

Does the computer act normally while in the safe mode?

It is as if your keyboard is interfering. Download and run https://brookhong.github.io/2014/04/28/keycast-on-windows.html
It is portable.

You can also try removing keyboard and use on-screen as a test.

It took me a while to figure out how to start the computer in SAFE mode. The F8 key led to the ASUS boot menu, which only gave the bootable devices (DVD drive and hard drive). F5 found the Windows boot menu, then I had to press F8 to show advanced options in order to get SAFE mode.

Anyway, this solved the problem of dialog box buttons activating on their own, and I was able to install software. Also saw no sign of moving windows or moving cursor. Once I rebooted into normal Windows 7 mode, I was also able to install software and saw no behavioral problems.

However, I had also changed the keyboard again, using an old Dell USB keyboard. Two changes at once (idiot!). It's possible that Windows installed drivers for this keyboard, which could have solved the problem. Will do some more checks tonight with both keyboards. Will post back to this thread if I have further problems.

Thanks everyone!
Jamie

Lenovo with related issue

I have a Lenovo Thinkpad x220I, running Win7 Pro 64bit, with a somewhat related problem. I bought the machine used, it has Win 10 onboard. I changed the hard drive and did a new install of the OS, using all the Lenovo drives I could find on their site for this specifica machine, using the serial number as reference. The issue the cursor will jump around on the screen. NO input from me, NO background services creating calls that I can see (background services all are dormant) NO connection to a network. When the cursor jumps, some times it apparently if mimicking a left mouse click.
What I have been able to recreate is that this only appear to happen on majority black screen. IE, using Ifranview, the default is a black blank screen. I changed it to white, and no problem. Also I am not using r3dfox browser and it defaults to a black theme. Again, I changed this to all white, and no more problems.
I had the use of this machine when it was new and had Win 7Pro 64bit installed from the factory. It did not have this issue then. It was changed to Win 10, and did not have the issue, as I also had use of the machine at that change. It has only showed up after the new SSD and reinstall of WIN 7. I suspect it's related to the graphics driver, but I'm not trained enough to know how to verify.
I have tried safe mode, and the problem persists.
Anyone have any thoughts?
If you need the full specs and listing of the installed components, let me know.

as the problem occurs even when using safe mode....generally means its NOT a 3'rd party driver

please run sfc/ scannow
and from the MS catalogue kb947821

might be usefull to run msinfo32.... copy/paste the results
