|The Recovery disks can usually be ordered for your particular model from the emachines web site online.|

In most cases, a Recovery disk set plus shipping costs a lot less than even an OEM XP Home CD.
(I'm assuming you bought in the US)
A ~ 300 dollar computer.
Try cleaning the laser lens on the optical drive with a laser lens cleaning CD. If you don't have one, most places that sell CDs or DVDs have them - even some "dollar" stores have them for a buck or two.
If you have two or more optical drives, try the disk(s) in another optical drive.
However, many bioses will only boot from a bootable disk in one optical drive. If a bootable disk is not recognized while booting, go into the bios Setup and find the list of optical drives - it's often near the Boot Order or similar settings - the drive you want to boot a bootable disk from must be first in the list, Save bios settings.
CD-R or DVD-R disks should read properly in any computer that can read CDs or DVDs, but other types of burned disks may NOT read properly in a drive they were not made in, and all optical drives are somewhat sensitive regarding which media (brands and types of burnable disks) work in them properly.
There is often a list of media that does work properly with the model on the optical drive manufacturer' web site, or if you added or replaced a drive, a new drive often has a printed sheet that comes with it that has that info.
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.
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.
The failure of BESTEC power supplies is probably the most frequent reason an emachines desktop computer fails to run, and in many cases, if the PS has failed completely, replacing the power supply does NOT restore the computer to working again - in those cases, the failed BESTEC PS has probably fried the mboard !
If the brand is BESTEC, I advise you to frequently take a look in the bios Setup at the current readings for +3.3v, +5v, and +12v - the actual value should be within 10% of the nominal value - if it isn't replace the power supply with one that is NOT BESTEC.
Or - get and install in Windows a freeware hardware monitoring program that can show you the same readings as in the bios for the current readings for voltages, fan rpms, and temps at any time. It can often be set to warn you or shut down the computer if the PS voltages get too far out of whack.
If it is failing, you can usually replace it with any decent standard sized standard ATX PS with the same capacity or greater.
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.
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!)
If that info is not in the ad for the video 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're a gamer....
In most if not all cases, the max capacity rating of the PS is an intermittant rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.
Don't buy an el-cheapo PS.
