New DC7900 giving error 513 front chassis fan not detected on boot. This only happened once I moved the PC, during setup it booted just fine. Fan is connecting and functioning properly, all the fan cables appear to be fully connected. I have already tried flashing the BIOS, removing the BIOS battery and clearing the CMOS. I do not have an extra fan to test with. Any help is appreciated. Thanks!
I was getting chassis fan not detected message. I unplugged CPU fan from motherboard, rebooted, received "CPU fan not detected" message. Plugged it back in and no more messages about either fan when it booted back up.
I replaced the fan and that fixed the error. Put the fan in another PC and that PC gave the error as well. Even though the fan works it looks like it is not able to be detected by the motherboard. Thanks for the help though.
