|"When XP cd is installed, it runs through some file installs and shuts off within 1 minute..."|
A computer may Restart when it, or the Windows installation on the hard drive, or the software on the XP CD, encounters problems, but it's NOT normal for it to shut off and stay off under those circumstances.
emachines desktop 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 properly 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:
If you can try temporarily connecting a used PS from a working system, do that first
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:
I no longer recommend Cooler Master, AOpen, or Sparkle power supplies.
Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .
What to look for, mboard symptoms, example pictures:

- he says there are STILL bad capacitors on more recent mboards.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
Then test the ram.
If you want to try a memory diagnostic utility that takes a lot less time to run a full pass than memtest86 does, this one is pretty good - Microsoft's
Windows Memory Diagnostic:
It can be toggled (press T) to do a standard or a more comprehensive set of tests - use the default 6 test one first - if it passes one pass of that, use the latter one. A few of the tests in the latter set are intentionally slower.
If you don't have a floppy drive, see the Quick Start Information at that Microsoft link for how to make a bootable CD of the Windows Memory Diagnostic (you need Windiag.iso - you don't necessarily need to use the program they mention to add it to the CD).
If the ram passes the tests......
Test your hard drive with hard drive manufacturer's diagnostics.
Seagate's SeaTools will test (almost) any brand of hard drive.
Do the long test.
The Dos bootable versions of SeaTools can test the hard drive when Windows will not load properly, or even when the drive has no data on it.
It the drive itself passes the test, any data problems on the drive can be fixed one way or another.
