Question about Dell Computers & Internet
Check the fan, maybe the fan is stuck, dirty or just at the end of it life cycle
Posted on Apr 07, 2015
If the machine boots up and you see the operating system start.
Then the loud humming could be fan dying as william stated.
If the fan speed max's out and the fan blades do not turn. It will sometimes hum very loud. The screen blanking out could be the system reaching heat levels too high. PC's often have more than one fan. Open the case and check for dust clogging the system.
Blow this out with compressed air. Vents, fans, fan blades etc.
Then see if the system runs within normal temps.
Note: hold the fan blades while using compressed air. You do not want these to spin at crazy speeds which will happen with the compressed air. Replacing any of the internal fans is simple.
Usually 4 screws and a power plug.
If the fans turn and do not pause or hang. I would then suspect the power supply. If your comfortable working inside the computer.
Switch out the power supply and hopefully this will resolve the loud humming. I have actually watched as a power supply died.
Humming noise then a little wisp of smoke. Dead as a door nail. :)
Good luck and hope this helps.
