This is NO JOKE!
This is particularly applicable to Windows PCs, but it's really the same for all operating systems and architectures. This is the first procedure to use, before you call any technician!
Here it the magic procedure:
- Shut down your PC normally, if possible.
- Unplug the external device(s) you are having problems with.
- It's best to unplug ALL external devices except for the mouse, keyboard and network.
- This is particularly important if you are having problems with a USB or other plug 'n play device or are having problems getting a PC to boot up properly.
- Remove any floppy, memory stick, CD or DVD that may be in one of your optical drives. These all can keep a PC from booting up properly.
- Unplug the PC from power.
- Yank the power cord out of the back of the PC or turn off the mechanical switch on the PC power supply.
- PCs are not really turned off unless you disconnect the power!
- You have been warned!
- Wait 15 seconds.
- Plug the PC back into power.
- Turn it back on.
- Wait for the PC to boot normally and log in.
- You need admin privileges to install new hardware or reinstall old hardware.
- Reconnect only the problem external device, if there was one.
- Then test your PC to see if the problem went away.
- Plug in and test each external device previously disconnected.
Note: USB external devices are plug n' play. PS/2 mice are not. A PS/2 mouse must be connected at boot up time. If your PS/2 mouse doesn't work, make sure it is connected and reboot your machine.
