I have an ASUS computer and moniter. when I turn the computer on, the fan inside is really loud, and all the moniter does is show the ASUS logo and it says `No Signal`, and the moniter turns off but the computer statys on.

Get it repaired in repair shop? OR.....
Asus x553m this is Notebook not a motherboard,
power pack AC attached both ends,? not wrong pack?
main battery removed FIRST. they short, and overload the DC power system inside. the battery on this PC is BURIED DEEP.
remove the center power plug on battery , as seen in video.
vid frame 4:15, SEE?

screen 100% black, ever shows any text ever or Asus Logo ever.
100% black?
does the fan run inside, are all vents clean, so it can not overheat

the cables break easy if not up to doing this with no damage,
don't.

its becuse your post bios screen is hidden you can veiw them by clicking tab on the keyboard when the printer starts it will show the post bios details

Sounds like its just 1 of the fans inside the case needs replacing or possibly the fan inside the power supply. These dont cost much and are easy to replace.

On some computers, when you turn it on, the fan starts to run at 100% of its speed, i.e., very noisily.
Then, when it is detected that the computer is functioning, and _not_ over-heating, the fan will slow down, and quiet down.

So, what is the nature of the "loud sound" ?
Continuous? Beeps, in some pattern?

Take the computer to a qualified technician, for better trouble-shooting.

If you mean after the computer performs the self test the screen goes blank and stays blank, eventually turning off you are having a hard drive problem. When the computer boots you should see an E-Machines logo and/or a self test on the screen. That is done by the motherboard as part of every boot up. After that the motherboard passes control to your boot device and loads your operating system. If your computer stops booting at that point, your boot device is not working properly. That could be caused by many things - virus, hardware failure, power outage. If you really mean you see nothing at all on the screen when you press the power button your computer simply is not working at all. Open the case, blow all the dust out of it and reseat all components you can, then try again.

Check the coolant between the CPU and the cooler to ensure it's not simply over heated.
