Q: Keyboard & mouse stop working when Vista starts. This thread is locked from future replies

Sometime this morning my keyboard & mouse stopped working (both wired USB). Multiple restarts have had no effect.I was not the user at the time & can not give any additional symptoms.

Restarting shows that the mouse & keyboard are receiving power & working up until Vista starts. The keyboard can be used to select safe mode. Going into the BIOS works. If I get to the system repair screen the mouse works. However when the system starts Vista (safe mode or normal) the mouse laser goes dark & the keyboard stops responding (the Numlock & Capslock lights stay in whatever state they were in but can not be changed).The start of Vista continues until it reaches the select user screen; at that point I can not continue without a mouse & keyboard.I have tried all usb slots with the same results. There is no ps/2 port.

Physics Guy,
Have you tried unplugging them both and booting the computer up and then plugging them in to see if it finds new hardware?  Did you try a full power down and not just a restart? 

If that does not work and you don't have another keyboard and mouse to try, you are going to have to try to do a system repair.  It sounds like the drivers for these devices got corrupted somehow.  You will need to boot from your Vista DVD and run system recovery.

If you have a Windows Vista installation disc, you need to restart (boot) your computer using the installation disc. If you do not restart your computer from the disc, the option to repair your computer will not appear.

If you have a Windows Vista installation disc:
1.  Insert the installation disc.
2.  Restart your computer.
Click the Start button , click the arrow next to the Lock button , and then click Restart.
3.  If prompted, press any key to start Windows from the installation disc.
Note: If your computer is not configured to start from a CD or DVD, check the information that came with your computer. You may need to change your computer's BIOS settings. For more information, see BIOS: frequently asked questions.
4.  Choose your language settings, and then click Next.
5.  Click Repair your computer.
6.  Select the operating system you want to repair, and then click Next.
7.  On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem, and if necessary, it might restart your computer as it makes repairs.

If Startup Repair is a preinstalled recovery option on your computer:
1.  Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
Click the Start button , click the arrow next to the Lock button , and then click Restart.
2.  Do one of the following:
• If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you will need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
• If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to repair, and then press and hold F8.
3.  On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press ENTER. (If Repair your computer is not listed as an option, then your computer does not include Startup Repair as a preinstalled recovery option.)
4.  Select a keyboard layout, and then click Next.
5.  Select a user name and enter the password, and then click OK.
6.  On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem and, if necessary, it might restart your computer as it makes repairs.
