Press and hold the button for about 30 seconds. If that doesn't clear the BIOS (keep the power cord disconnected): -- Remove the silver, round battery from the motherboard - you should see the "+" sign , -- Press the computer's power-on switch for 10 to 15 seconds. -- Wait another 30 minutes, -- Re-install the battery to the board "+" sign facing you, -- Press and hold the CMOS Clear button on the back of the board. -- Now re-connect power to the computer and try to enter the BIOS by pressing the <delete> key. Reset the BIOS settings you need to run your system - the boot order of your drives and the first HDD to load. h3ndr1 August 27, 2010 6:55:07 AM Best answer selected by h3ndr1.
