Re: CPU fan failure
The bearings in the fan or internal mechanism may have burned out. If the fan does not generate a cool enough environment, you run the risk of frying the processor and other motherboard components that are temperture sensitive.

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.
1. if you have a new hardware recently added ,remove that hardware to make sure it is not the cause of your issue. If after removing the
new hardware your computer works it's likely the computer is either not
compatible with the new hardware or a system setting needs to be changed
to work with the new hardware device. 2. Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for the CPU) your computer could be overheating
or detecting the fan failure causing the computer not to boot. 3.check all the connections.
Hello Sounds like you need a new cooling fan.You may be able to save yours with some electrical contact cleaner spray. Remove fan and spray. The cpu will heat up quick and shut down everything to protect itself.Im sure once you get a new fan you will be up and running again. You may consider reapplying new conductive paste to the processor while you have the case open.
First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:
LEDs near Caps Lock and Number Lock keys blink when starting notebook
LED lights near the Caps Lock and Num Lock keys will blink if an error
is detected during the start up process. The LEDs will blink a number of
times in a sequence and then stop. The number of blinks in the
sequence indicates what component caused an error when it was being
tested during start up.
If the LEDs stop blinking and the
computer does not start, you can press the power button again to repeat
the tests. Count the number of blinks, and use the chart to identify the
Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

Phoenix BIOS beep codes
CPU test failure
The CPU is faulty. Replace the CPU.
System board select failure
Replace the motherboard.
CMOS read/write error
The real time clock CMOS is faulty. Replace the CMOS if possible.
Replace the RAM module if possible.
Keyboard controller failure
The keyboard controller has failed. Replace the IC if possible.
CMOS RAM power bad
Replace the CMOS battery or CMOS RAM if possible.
CMOS configuration error
The CMOS configuration has failed. Restore the configuration or replace the battery if possible.
Video memory failure
There is a problem with the video memory. Replace the video adapter if possible.
RAM test failure
System RAM addressing circuitry is faulty. Replace the motherboard.
I would look at the cpu's before judging the fans on this, also if everything checks out with the cpu's then why don't you try a compund that goes on the cpu before the fan, this compond is safe and will knock like 6-10 C off the top of the heat. Also You need two fans blowiing out and one blowing in and do not interupt the ariflow, make sure you have no holes,such as missing slot covers ETC ETC.. there is not real rocket science to cooling on this manner, Thank you
OC failure = over clocking failure. Make sure the CPU fan is clean, free from dirt & dust. Check CPU fan plug is connected correctly. If the CPU fan still stops after a few seconds replace the CPU fan.
It's harder to find just a fan to fit your heatsink, which sits on your CPU. It is easier to find a new heatsink \ fan combo for your Intel. Use your manual to find what Intel chip is on your board. Use that information & search google for a heatsink & fan combo. Pay close attention to how your current heatsink is mounted to the Gigabyte board.
