Check your setup settings (BIOS) to make sure your booting from the correct drive. If the computer is trying to boot from the cd drive or USB, rather than the hard drive, you will receive this error message.
In My Humble Opinion, Heather, YOU can fix anything in your computer.You have replaced a Power Supply, and added a graphics card.1) The eMachines T5212 Desktop PC uses an Intel D102GGC2 motherboard,http://www.newegg.com/Product/Product.aspx?Item=N82E16813121031The motherboard supports an LGA 775 processor socket,http://en.wikipedia.org/wiki/LGA_775Instead of the processor having the contact pins, as in the older Intel Pentium 4 processors (Socket 478), the LGA 775 processor socket has the contact pins.http://www.pcworld.com/product/29441/emachines-t5212.htmlAfter the page fully loads click on the third view down, and the left side. This inside view shows the black rounded air duct, used on the processor fan.Here is a replacement Heatsink/Fan combo,http://www.cputopia.com/emachine-fan-t-series-t5212.htmlIt looks as though the unit comes apart. (unscrews)If so you can just replace the fan itself.IF not however, it means the finned aluminum Heatsink, AND fan remove.In this case you have to THOROUGHLY clean the top of the Processor, and bottom of the Heatsink, and apply Thermal Paste properly.I can guide you.[ I know you have been following the proper procedures, but I would hate to learn later that you haven't been, and I didn't post;Follow Anti-Static PrecautionsYour body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.Relieve your body of Static BEFORE working on your computer, or before taking those parts out of their anti-static bags, or cartons.Computer on a table, computer Unplugged from power, computer case open;TOUCH an unpainted surface, of the metal frame of the open computer case.This action will relieve your body of Static.IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return ]Be sure to clean in-between the fins of the Heatsink, before installing the new fan.Know you need to get a new computer?Only if it fits your needs.For myself it is internet, Youtube, Adobe Photoshop 7, and office programs.My Pentium 4 HT, model 540j, (3.2GHz), 2GB's of ram memory, and an ATI Radeon 9250, does just fine.If you are a gamer, and/or use 3D programs, and/or burn videos, then more 'power' is needed. IMHO.Windows 7? Windows 8? Yeah, whatever. I have Win7 on my new laptop. Perhaps one day Windblows will catch up with Ubuntu and the Compiz windows manager, lol!http://www.youtube.com/watch?v=tRAcskPNof4&feature=relatedFor additional questions please post in a Comment.Regards,joecoolvettehttp://www.intel.com/support/motherboards/desktop/d102ggc2/sb/CS-022441.htmIntel Desktop Board D102GGC2 Product Guide - English (PDF) = Motherboard manual in PDF file form.

Look at the middle cover (above the keyboard). there are two buttons that touch the power switch, the one to the left enables/disables the touchpad. If it shows an orange light it is disabled. Just press it, and be careful not to hit it when turning unit on.
Can you remove the front cover, access the rear of the button, clean, use silicon spray/ repair. Sometimes the plastic retainer/spring will break and not return the button to the out position.
from what i know, consensus of hard disks are plug and play meaning they won't need a driver to be installed because it automatically installs during startup.

Give a few seconds for the first page to come up, (Took 6 seconds for me), and for the PDF file to fully download, before looking through it. (Took 24 seconds for me)
1) Did you make sure the 24 -pin ATX main power cable, is plugged in tight? Lock on the side is snapped in place? Page 42.
Closer look at a 24-pin ATX main power cable, and it's respective connector,
Very sorry about your son. If you can't find the real problem, you can always put that hard drive into another PC to get the files. If so, be sure to looking to a potential "jumper" setting on that drive for it to be recognized.
It is possible that the cable is not making a good connection, make sure it is snug and that you have it facing the correct way.
You may need to get a new cable.
I hope this helped.
Good luck and have a good day.
I think it's a driver problem. Do the following;
1. Open "Control Panel"
2. Expand the "Mice and Other Pointing Device"
3. Uninstall your Touchpad from the menu by right-clicking on it.
4. After that, right-click on "Mice and Other Pointing Device"
5. Click "Scan for Hardware Changes" and it wait for your computer to automatically ddetect your touchpad and reinstall it.
Try using the touchpad.
The blue screen will have a ton of data with it, as they can be caused by many things from hardware failure to a virus. Gather as much information as you can from the BSOD (Blue Screen Of Death) and post it as a reply to this post.
Use CPU Z DOWNLOAD it HERE its FREE and it gives you detailed instructions on your PC.
Go to the Memory tab and it should tell you exactly if it has 4GB of RAM or less
Does it just shuts down or it reboots?
If it shuts down this type of problems can be resolved by scanning the computer for a virus or using the Windows Repair Disks. During boot if you can hit F8 and use safemode with command and prompt.
1 Type CHKDSK/F then hit enter
2 Press Y then hit Enter then reboot to see if this works.
If it reboots while booting up then.
Other things that might be preventing the computer to boot up most likely is the memory.
Take out the memory put it on a different slot or try a new memory.
Also make sure that the power supply fans are not dirty this prevents the computer to bootup.
