I Have a HP pavilion a1710n and i recently upgraded my case. When i did so i had to un hook the fan in the back of the case that was hooked up to the motherboard using a 3pin fan connector which was hooked to the system fan hookup. My new case now has a fan in the back that uses a 4pin molex connector. So now i have nothing hooked up to my motherboard. When i boot my computer it gives me a system fan error and wants me to press F2 every time to bypass the error. Is there any way to turn this off?
