    OK, I've read a couple of threads here and there about this message, but I'm still not sure if they apply to my problem.

    Basically, I stupidly started messing around in the BIOS (I am pretty **** with computers, I have no idea what I was doing) and I think I changed something to do with the fan. I think it had somehting to do with the speed of the fan.

    Now, when I turn on my PC I get this message "CPU FAN DOES NOT FUNCTION PROPERLY", with a continued bleeping noise. I can't get to the BIOS. Its is just a black screen with the message.

    Now I took it to a guy and he said that my motherboard has gone, and he could tell this by the bleeping. I am not sure however, as my computer seemed to be working alright before this accident in the BIOS/fan settings.

    From what I've read around, it seems like I need to get to the BIOS, to adjust this setting that I changed when messing around with the Fan BIOS. I can't get to the BIOS though. The computer man I took it too said that he's 'cleared the BIOS' (which I gather means he just took out the battery) and 'changed the fan'.

    But I'm still not convinced. From what I've read, it is a case of running a high speed fan where the usual fan would be, thus reaching a high enough speed to enter the BIOS. Is this possible? I could perhaps power my normal fan though something else, enabling me to put a High speed 3 pin fan in the usual slot. Is this possible? It's something I've read and yet to try. Is it easy enough to do?

    I'm pretty sure that the problem I have is fixable, just wondered what your take on this was. Cheers guys..

    Simple way to check if your cpu fan is broken, open up the case and see if it turns on. Some boards do not register certain cpu fans properly. For example my own asus board brings up that error at every bootup but its because i have a modded zalman cpu fan
