Specs: unkown
I recently got a computer from my uncle who now
moved to the philippines, it is an emachines
computer. He also idn't give me any books or anything
that belonged to it other than the mouse and the
keyboard. It worked fine for 4 weeks, but now it won't
turn on. Here's what happened, I was in a program
called "Windows Movie Maker" and WMM is notorious
for freezing and taking forever to work. Anyway, while
i was doing a project on WMM. The computer froze,
becuase of it and so i manually turned it off by holding
the power button for 10 seconds and i didn't bother to
turn it back on becuase it was really late and i needed
to get to bed. So anyway, the next day i pressed the
power button and the light went on but then it turned
right off. Then i kept pressing the button over and over
to see if it would work, but no luck. I even unplugged
all of the wires and got the dust off the fan in the
back, but it still will not stay on. Now i did look at
some of the other problems that people had with thier
computers, and i'll try that but i just wanted to get a
second opinion. So do you possibly know what the
problem is?
Also i am not at home, since the computer my uncle
gave me is the only one that works, i am currently at
school so i don't know the information that it asked
me is correct. But i know it must be somewhere near

Open up the case.
Make sure the 3 or 4 wire cpu fan is connected to the 3 or 4 pin cpu fan header on the mboard.
Make sure the cpu fan spins when you try to boot the computer. If it doesn't, many more recent mboards will shut down automatically within a very short time to prevent the cpu from burning out when no rpm is detected from the cpu fan header.

emachines computers are well known to have el-cheapo power supplies that tend to fail more often than average, and when the power supply fails completely, they are a lot more likely than average to damage something else, often the mboard.

If you have not been fiddling inside the computer case just before this happened and have not changed the ram installed in it, it is very likely that if you replace the power supply BEFORE it fails completely, doing that will restore your system to working again.

Unplug the cord to the computer, or otherwise switch off the AC power to it, open up the computer case, and find the label on the power supply - if the brand is BESTEC I advise you, if you find ANY indication the power supply might be in the process of failing, DO NOT trying booting the computer anymore - if the PS fails completely there is a strong likelyhood it will trash your mboard !!!!

Failing power supplies are common and can cause your symptoms.
They often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.
Check your PS.
See response 4 in this:

DO NOT replace the power supply with another BESTEC one!
In most cases you can replace it with a standard sized standard ATX power supply.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.
See response 3 in this:

Your power supply must have at least the minumum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD!)
You can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you need to get a PS with more capacity, you can usually replace it with any decent standard sized standard ATX PS.

"Product: Emachines El1210-11 desktop pc"

The second character in the model is an L, not a 1.

Assuming it was bought in the US:

eMachines EL1210 Desktop Series

NOTE that the specs there state this computer series has only a 200 watt power supply !!

If you install ANY graphics card in a mboard slot, you will probably need to get a power supply with more capacity!! See above !!

OR - you may purchase recovery media online.

How do I reinstall the Operating System on the computer?
(you're actually re-installing everything that was originally on the computer).

According to this page:

EL1210-11 has this mboard:

thanks for the advice. I will try them when i get home.
The fan in the back does spin when i press the power but then it stops when it shuts off on it's own.
Belive me i haven't done anything with the insides of the computer, i'm no computer tech person. I'm just a simple graphics designer that keeps having computer problems.
