hi there can anyone help with this weird problem when trying to boot up computer, i get the message "cpu fan not connected" and a long bleeping noise then the computer shuts down.I know that the fan is connected and working fine, i know this some thing to do with a bios setting, and can be changed but the computer shuts down so fast it wont let me get into bios to change it, any suggestions?

reset your BIOS through the jumpers (make sure you take the battery out first then re-try if all else fails, change your fan and re-try computing.net rocks

hi thanks for the reply, as i dont know much about computers could you tell me how to do that ( resetting jumpers) and which battery i have to remove is it the big one on the mother board..?

Some motherboards have jumpers, some have two solder points, and some have no jumpers. On some motherboards you apply power for two to five seconds after changing the jumper, and some you don't. All in all, it's best to follow the manufacturers instructions in the motherboard manual. If you don't have the manual, post the make and model/Rev level of your board, or your system make and model if it's a proprietary system (DELL, HP, Compaq, etc). It's a good day when you learn something

the mother board is Jetway there is a set of numbers on it beginning with 6 then the word aspro but cant see the rest ( sorry for lack of details)

Have a look here. On the left click on "Troubleshooting" then click on "Mainboard". It's a good day when you learn something

thanks will give it a try
