My problem is that at start-up I recieve an error message stating that my cpu fan failed and I will have to hit f2 in order to boot my system? Both of the fans on the back of the tower appear to be working fine and are pretty clean of dust. What is causing this and how do I fix it?

That is the heatsink fan attached to the CPU. I would advise not running it until it is fixed Give us the make and model of your computer and we can walk you through the process. It might also just be clogged with dirt and not able to move. Removing the cover and a good cleaning with canned air would be recommended

I took the covers off and cleaned with canned air and I still have same problem. Fan speeds seem normal. Both fans are rotating. Temps seem good. Not sure why I am getting an error. Computer seems to work fine other than having to hit f2 everytime I start the computer tower. Anyone help on this one? Do I need to go in somewhere and reset something?

With the case open you will notice that there is a board that all of you external devices connect to at the back of the case. This is the motherboard, and depending on the make and model there should be a fan sitting on a heat sink which is attached to the PCU, if this is not running the CPU will quickly overheat and will shut the system down.

Some models don't have a fan and depend on a large passive heat sink with a plenum to draw air over it, if the grill at the front of the case is impeded by dust and other material this could cause the CPU to overheat and shut down.

Until you provide us with the make and model of your computer we won't know what type of system you have and will not be able to address your specific problem.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

The make of the computer is HP. It is an HP pavilion 700 series, a 754n. I went and purchased a new fan and it did not help. Still gettting a cpu fan failure upon start-up. I do not have a fan on top of my cpu unit. I have a fan in the rear of the tower with a piece of plastic duct work directing the air over the cpu unit fins. Is the sensor on my mother board not working properly and if so what do I do about that?
