Well I have a stumper for you great hardware troubleshooters.
I have a IBM PS2 Keyboard and a M$ Intellimouse Optical which have been good old friends for years. They have been hooked up through a Belkin 4 port KVM for nearly a year and been flawless in operation. About a week ago I started getting all sorts of strange occurances on my computer… the Start Menu would pop-up (as if I had hit the Windows Key), the System Properties page would appear for no reason, the Run command window would do the same. Num Lock turns off automatically, and when it is on the Number Pad still works as if it were off.
I wondered if I was being hacked, but my firewall showed no strange traffic. I wondered if I was infected with some strange virus, but Symantec Corporate comes up with nothing, and I have found no virus descriptions matching my symptoms…
Suddenly some new symtoms have appeared… my mouse functions have gone haywire.
Left-click sometimes will not execute the expected operation. Middle click actually invokes the Alt-Tab window switching. Right-click opens the task manager.
I thought perhaps it may be my KVM switch was on the fritz, but after removing it completely from the setup… the problem persists.
I tried pulling out an old Dell mouse and the same occurs… I tried dusting off and old keyboard but there is no change… this is almost rendering my workstation usless…
Has anyone ever experienced anything like this? Can anyone think of something I can do to remedy this?
