Fan works randomly....when it's not working plug

When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

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=N82E16813121031

The motherboard supports an LGA 775 processor socket,

http://en.wikipedia.org/wiki/LGA_775

Instead 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.

After 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.html

It 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 Precautions
Your 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!

Three causes of ovheating:
1) Dust. Dust inside the computer, Dust around the vents, fans, cpu and heat sink. Take a can of compressed air and clean the dust out of the computer.

2) A Fan not working. Make sure the fan inside the Power Supply where you plug the power cord in works. Also there is a fan that sits on top of the CPU and Heat Sink. Make sure it works. Normally the system will give you an error message if the fan is not working.

3) Thermal Paste - The Thermal Paste around the cpu and heat sink has dried up or is too thin to keep the unit cool. Apply a fresh coat of Thermal Paste on the CPU and Heat Sink.

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.

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.

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.

White is your neutral so white goes to white. Blue on the fan is for the light kit you need to wire that to the wire from your switch so it works the lights. Black is the hot wire that is always hot not switched so tie that to the wire that is not on your switch. Green is ground so green to green. white to white / green to green/ black to black/ red to blue/

If my sources are correct, (Haven't worked on one in my shop yet), the eMachines T5212 desktop computer uses an Intel D101GGC2 motherboard.

The Intel D101GGC motherboard is Very similar,

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,

2) Did you plug in the 4-pin ATX +12 Volt power cable?

That's power for the Intel Pentium D model 805 processor.

Are the cables (Wires) from the Front Panel of the computer, plugged in correctly into the Front Panel header on the motherboard?
Page 37

Are you sure the DDR2 Sdram ram memory module/s (Stick/s) are plugged in tight?

The best method is to remove it, or them, and reinstall.
This way you are assured.

Most of the time a ram memory module, or more than one, will be bumped loose when installing a Power Supply.

I have called you and left you a message with my phone number. Please take the time to call me back.

Thanks, Frank

Here is the website for that particular mother board. This should give you what you need.
