System fan has failed CQ3085D

Hi

 

The message "system fan has failed...press f2 to continue" was displayed on boot. The computer model is CQ3085D compaq presario desktop with windows 7 32 bit home premium. There were no changes made to hardware prior to appearance of the message. When I tried entering BIOs, I cannot find any information on the system fan. The hardware diagnostic tool also has no information on system fan but only information on cpu temperature. Can anyone advise on what I can do to resolve the problem?

Thank you

 

Andrew

System fan has failed CQ3085D

System Fan refers to a fan other than the CPU cooling fan connected to the motherboard. On your motherboard it is called the Chassis_Fan.  Does your PC even have a system fan? If there is a fan connected to the chassis_fan header then it has probably had a speed sensor failure. I suggest unplugging the three-pin connector and plugging it back in again and then booting up your PC.  It is not a critical item, but it should be replaced with a new fan of the same size.

 

What is the installed operating system?

System fan is usually a case fan that plugs in to the MoBo and used to keep the internal temperature of the case down to correct operating range. Is your case fan running? If not, did it get unplugged? If it's plugged in and not running, try unplugging and replugging the fan to the MoBo. If that doesn't solve it, buy a new fan, they're cheap. CAUTION: be sure to ground yourself to the case when working inside a computer as static electricity can wreak havoc on the components contained within. Just touch the case prior to touching any of the components inside and try to maintain contact with the case while working inside. There are grounding straps made for just this purpose, but if you are careful you can make due without one.
