Just a quick question. I replaced the faulty chipset fan on my A8N-SLI deluxe motherboard today. When I rebooted I got an error message saying something like "Failed CMOS Checksum" then "defaults loaded" I pressed F1 to continue, loaded into windows no problem. I have since rebooted and the message doesn't come up anymore, just that one time. Anything to worry about? Thanks in advance!
