My receiver turns off and on and trys to run a system update but when it is complete it turns off and you can here the fan blowing and then it starts the update again. It will only show the channel you were on for a second maybe.

The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Hello user...you are receiving this message at start-up because, in your bios system settings, "run fast diagnostic test" is enable...CPU fan is like a computer fan but attached with the cpu to cooled the cpu so that the cpu will function properly so as the computer...perhaps there is a problem with the fan, so its not running when the computer starts. This may harm your CPU, as a result may blow the circuits in the motherboard and eventually your computer will crash....for a technical advice, you may want to visit the nearest PC repair shop and change the cpu fan..

that is the problem . who ever hooked up the fan it is cut into something. I bet if you umhook the fan you will stop blowing fuses

Fuses blow because of higher than normal amperage in the circuit. Not sure what circuit the blown fuse is for but if it is for the fan the fan may be shorted therefore blowing the fuse. If you put fuse in while the ac was still on try shutting off the ac then putting the fuse in. See if it blows then if it doesn't then turn the ac on and if it blows you have at the very least isolated the system at fault.

How long havew you had the present motherboard in your computer? if over 3 years (and used on a dayly basies more then likely, your motherboard is in need of replacment because the capasitor/s are leaking (not giving the proper voltage to start and hold your computer at proper levels

this sounds like one of your capacitors has failed
using an insulated screwdriver and, power not applied remove the spade connectors from one of the capacitors then short the capacitor to ground to discharge it replace the spade connectors apply power and, turn it on if the problem changes replace the capacitor (a bad capacitor usually is "bulged")
there are usually two capacitors a run and, a start

I don't do many BIOS updates (mostly because they can be fatal to your system if they go wrong) but my general understanding is that if the update does not finish then you are out of luck. Your best bet will probably be to replace the motherboard completely.

Hopefully someone on here has a better idea though...

Best of luck :)

Either the dual run capacitor has failed and is not providing the help the motors need or the compressor has shorted out internally causing the fan to run when the a/c is off and then blowing the fuse when it trys to turn on.

Fuses are a protection device and I guess that this is for the condenser section and compressor. If they blow right now when it is turned on would indicate that there is a short in the wiring or motor or compressor. If it trys to start and the outside fan starts and the compressor just humms and blows fuse, you have a locked compressor. Might check run capacitor or install a hard start kit and see if it will brake it loose, if not bad compressor

Even when the power is off at the unit outside the thermostat will supply power to the contactor of the outside unit. This may give a hum or buzz as you stated. If when the power is on to the outside unit the fan tries to start but only hums the motor may be bad. Does the compressor start and run?
