Windows 7: Keyboard/Mouse randomly stop responding (PS/2)

Keyboard/Mouse randomly stop responding (PS/2)

Recently I have been having this problem where my PS/2 keyboard and mouse both stop responding. The lights are still on, but neither work. Sometimes it happens just to my mouse, and not the keyboard, but usually both. When it happens, they are not responding for anywhere from a few seconds, to a few minutes (but by that point I restart the computer). If it happens just to the mouse, putting the computer to sleep using the keyboard and wakening it again fixes the problem.

I have tried to update the drivers in device manager by letting windows search for them online, but it says they are up-to-date.

I also checked all the connections inside the computer, unplugging and re-plugging each one as well as air-dusting.

Is anyone able to help me find out whats wrong, or how I can fix it?

Thanks in advance.

EDIT: If I can't find a fix, I think I will just purchase a USB mouse and keyboard, but I'd rather try fix the problem first.

EDIT 2: I am still very much in need of help.

Well, this can be hard to fix as normally we will suggest opening task manager or resource manager when this occurs to see if you are experiencing high cpu usage, which can cause input devices to become unresponsive. But to open those, you need...a keyboard and/or a mouse! If it only effects the mouse, you can try opening task manager with the keyboard (Ctrl+shift+Esc), and see if you are experiencing high CPU usage.

You can also try unplugging the unresponsive device, and plugging it back in to see if that re-enables it. If it is not an actual PS2 issue, a USB device may not correct the problem. If the problem was happening regularly, you could either boot to safe mode to see if it occurs there, or (better for prolonged testing), perform a clean start to see if there is a conflict causing the problem.

Also, the event viewer may provide some help

I will open the task manager next time it happens using the keyboard and see if anything is happening, unplugging the mouse and reconnecting it does nothing at all I will boot in safe mode, or try a clean start. Thanks for those links too!

I did some searching for random mouse freezing, and The Software Protection service entered the stopped state. Seems a commonality is logitech devices. It was also reported that switching to High Performance power plan has fixed this for some. I will ask the Gurus if anyone has any ideas. A Guy

You might also try looking in Device Manager to see if there are any conflicts for the keyboard and mouse device entries.

What security software are you using? Also, have you updated to SP1?

A 7036 is a common and normal occurrence. The Service Control Manager issues a log entry every time a service is started or stopped. It's not necessary to have all services running if the PC is idle.

The only Logitech devices I have are a wheel (which I've had for a while) and a microphone, which uses the microphone jack, and not USB. I only got it about two weeks ago, I doubt it is the microphone because it only uses the jack and has no software.

I'm using McaFee (not at home, no idea how it's spelt).

I'm using Windows 7, and I was not aware there was a SP for it. I can check later tonight.
