the sound you are hearing or heard could have been power surging through a powersupply unit that just blew.. hopfully it did not effect any of the other hardware..to trouble shoot this you can do one of two things..1 disconnect the 20/24 pin powerconnector from the motherboard 2 disconnect the cpu power connector 3 disconnect the 6pin power connector from the graphics card if there is one some machines have onboard video chipsets if thats the case then no worries 4 disconnect the Harddrive power 5 jump the power supply to see if you get any power from it any questions on that go to youtube and type in how to jump a power supply... or option 2 is buy a new power supply make sure its 80plus certified and replace it...i know its a lot of work but i hope this has helped you

Hello

Try f2,then let the screen come up.This is your bios settings,dont change anything.

Next hit the esc key,answer yes or y key.Pc should reboot normally.

If this doesnt work hit the f10 key and select your hdd or hard drive in the options,and reboot.

I had this happen to my emachines T1842 about a year ago. I replaced the power supply and it worked fine. It was about 25 bucks but fixed my problem. Make sure the red switch on the back hasnt been messed with. it should be on 115. If you have moved it, it may have blown a fuse inside the power supply.

it sound like you may have a motherboard problem you maybe looking at getting a new motherboard if the fan starts but nothing else happens.
its not a power problem this will be dealing more with the motherboard its self. try removing the hard drive if the screen says no hard disk found then your board is most likely ok. try rebooting and hitting f8 to insure that the computer is not stuck in a hibornation state. this is not likely but possible. do you see lights in the front of the computer? this will let you know that your getting enough power flowing thru the unit. if all this fails your motherboard has gone bad on you

Emachines are notorious for having faulty power supplies. If your lucky you just need to replace the power supply. I've seen a lot of them where the power supply also fried the motherboard.

Please don't forget to rate this solution.

I am an Medion specialist. These computer suffer with problem motherboards which often cause random restarts and shutdowns. The same applies to all Advent and Emachine computers sold via the high street stores. Need help to repair, email me me at [email protected] or ring me on 07926-106150

Sounds like the power supply is faulty. Power supplies are very dangerous to try and repair, even for qualified technicians. I would also suggest not trying to plug it in or turn it on until the new power supply is in place. Faulty power supplies have been known to cause motherboards to permanently malfunction. Note: researching your issue, I came across several forum posts with complaints about emachines and their power supplies. The best way to solve this problem is to purchase a new power supply. If shopping online, www.tigerdirect.com and www.newegg.com are two places that specialize in PC hardware. A 400-watt power supply would probably more than do the trick for you. The cheapest one I found was $18.00. Make sure the power supply is compatible with your motherboard before you buy.

try to reseat the power cable of the computer and power it on again
