Sometimes when you get a surge the settings in the CMOS can get all funky and can cause the motherboard to not properly identify and use certain components on the motherboard. I had this happen alot, especially when someone tried to plug something in the front usb ports, like a digital camera, etc... To fix this, I reset the CMOS settings. To do this follow the instructions below. It's not gauranteed to work, but won't hurt anything if it doesn't and so is worth a shot.
To reset the CMOS do the following:
- Turn off your computer
- Remove the power cord from the back of your computer
- Open the side panel
- Locate the CMOS battery (it's shiny stainless steel about the size of a nickel) and remove it
- Wait at LEAST five minutes
- Put the CMOS battery back in
- Re-attach the side panel
- Re-attach the power cord to the back of the computer
- Power on your computer
You will probably get a CMOS checksum error first time booting after doing this. Don't worry this is NORMAL. It only means that you need to set the date & time on your computer again. It should say to press one of the F
unction keys or the DEL
key to enter SETUP. Do so and reset the correct date & time. Make sure you SAVE CHANGES before you exit setup.
