I removed the PS2 mouse and PS2 keyboard (into one usb plug thru a PS2 to usb adapter) from the Dell Optiplex G280 Minitower while it was running (Windows XP Pro SP2) . I put the usb plug back in and got a Found New HW Wizard on the screen. (Why ????). Since then the mouse and keyboard fail. When a **different** PS2 mouse with a **different** PS2 to usb converter (that previously worked by itself with **this** Optiplex) is plugged in, same result. I reboot, same result. Try other usb plugs on the back, same result. Try other usb plugs on the front, same result.. Hence the Optiplex must be thrown in the garbage.
BIOS, there is no keyboard so I cannot type F2. Task Manager, there is no keyboard to type cntrl alt del. Continue with the found new HW wizard, no the mouse does not work to click the Next button. Oh, BTW we no longer get to the Found New HW wizard because I cannot get past the log in window.
Of course on any other PC in the entire world this would not happen because they have the PS2 connectors but not the Optiplex. The only PC in the world with no PS2 connectors. Brilliant, Dell Computer, just brilliant !!!!
So I must throw it away. Completely hopeless.
Any comments? A solution perhaps.
Note: The PC is being brought down by a lite tap on the power button, not by holding the power button in for a long time because the lite tap causes the PC to come down as if I used the Windows Start button.
