Question about eMachines Ultra-Slim ER1401-57 (PTNBZ02003) PC Desktop
No hardware mods: ACER EMACHINES ER1401;AMD Athlon II Neo K325 dual core CPU with 2GB DDR3 RAM and 250GB SATA hard drive Fault description: On turning on the power, before pressing the on button, the green LED comes on and PC begins to start up. After about 5 seconds it powers down adn will not turn on via the on/off switch. The extrenal power supply LED was showing a green LED but I ordered a replacement in case it couldn;t deliver the required load. No change with a new power supply. Running win 7 pro no hardware mods:
Wow, that's different!
(First time I've seen one. Apparently I lead a sheltered geek life, lol!)
All-In-One desktop computer the size of a laptop.
Approximately 8-1/4 inches by 8-1/4 inches, and 1-1/2 inches Thick.
Uses air to cool the hardware components inside, just like a laptop, or desktop; and has a small internal fan.
This means 'Gunk' can be 'inhaled' also.
'Gunk' = Dust, dirt, hair, lint, food crumbs, carpet deodorizer,......you name it.
When a Processor overheats it turns off. (BIOS turns it off)
This is a fail safe feature that is built-in. Keeps the Processor from burning up. (Literally)
Also a Processor has Thermal Paste on it. A medium to fill the imperfections of the surface, of the top of the Processor, and bottom of the finned Heatsink that sits on it.
Also is an excellent carrier of heat.
Thermal Paste dries up. I know, hard to believe with a computer that may only be a year, to 2 years old.
However look at the design.
Crammed into a little box, just like a laptop. Heat IS an issue with this type of design.
NOT a cure, just part of the diagnosis;
Computer unplugged from power, press the Power On button in, and hold it in for a count of 10 seconds. Let go.
Do this procedure two more times.
What you are doing is depleting any residual power.
Now attach the plastic straw provided, to a can of compressed air for computers. Break the lock tab off of the top of the nozzle.
Spray air in those side ventilation holes.
IF possible try to poke the straw in the ventilation holes. (Slots)
HOLD onto the straw with one hand, and the can of air with the other hand; as the straw has a tendency to shoot off.
Don't want the straw to land inside the computer.
Try to 'dust' the computer out with the compressed air.
Allow the computer to sit 5 minutes, then plug back into power.
(THAT is, plug the AC adapter into computer, THEN plug AC adapter into power)
WAIT 1 minute, turn the computer on.
Just want to see if it runs for a longer time.
Computer needs to be opened up, and cleaned.
ALSO suggest replace the Thermal Paste.
If a Thermal Pad is used, carefully peel it off, fly it at the cat.
They are junk, and can't be reused anyway.
PROPERLY apply fresh, new Thermal Paste.
How to open the case? Dunno at present.
Briefly looking at it, I would assume the Stand has to come off, then there may be a parting line at the bottom. A Spudger Tool is eased into the parting line, (NO more than 1/4 inch), and the case is slowly popped apart.
One side of the case will have Latches. The other side will have matching Tabs. The Tabs snap into the Latches.
It isn't a slang term. The cases literally make a popping sound when the Latches release the Tabs.
The back is a Back Cover. This is the side that should remove.
About all I have for now.
Please post additional questions in a Comment.

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Test all leads that attach to your hard drive power and data cables IDE SATA the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty Make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty. Computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error. Even something as small as a faulty electrical or fan lead can cause you problems Motherboard and a Hard Drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail. Check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in. Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490 Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink. Another possible reason could be a memory dump you might be running to many programs at the one time putting to much strain on the CPU central processing unit. If you can get your computer stable enough scroll to bottom toolbar bottom of screen right click select task manager applications you will see whats running if you see anything you dont need running select end now also under processes see what is ticking over again if you see something you don't need to be running end now or you might uninstall that program and some unnecessary programs not having enough computer ram can cause memory dumps If you are not sure if a module is right for your system use the Crucial Memory Advisor tool for a list of guaranteed compatible modules. first you will need to select the manufacturer from a drop down list then select your product line from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system you should always for a guarantee on any ram modules when purchasing them or buy working pairs if possible. You might have a virus or malware. Download at least one of these of course it will depend on your operating system. http://www.majorgeeks.com/Microsoft_Security_Essentials_for_Windows_d6242.html microsoft security essentials your operating system must be registered Win7/Vista/XP 64 bit http://majorgeeks.com/downloadget.php?id=4281&file=1&evp=dbb3b0aebe6a6a4ff18089a6489a5e62 anti malware free edition Win XP/2003/Vista/Windows7 http://windows.microsoft.com/en-US/windows/products/security-essentials/product-information malware protection http://100-downloads.com/download.php?p=615 windows xp microsoft security essentials http://100-downloads.com/download.php?p=614 windows 7 microsoft security essentials Capacitors look like small metallic canisters and they are found in many different computer components including computer monitors, computer motherboards, video cards, power supplies and a variety of other consumer products. A bad capacitor can cause a variety of computer problems, but if you can identify the faulty capacitor you may be able to replace it and save your computer.
Capacitors, sometimes also called condensers, are used to store energy in an electric field. In the context of computing, capacitors are used to block the direct current being circulated around the motherboard. A typical capacitor should last up to 15 years, but some computer manufacturers use substandard capacitors resulting in shorter lifetimes. Computer Problems b> When a capacitor has gone bad on a computer you may experience a large range of problems. The computer may have trouble booting up, or it may shut down without notice after running for only a short period of time. The most common problems associated with faulty capacitors are that they cause unexpected computer crashes and general reliability issues ranging from read/write issues to distorted screen images. b> Identifying a Bad Capacitor b> To identify a bad capacitor you will need to open your computer case and locate the capacitors on your motherboard. A bad capacitor may exhibit swelling at the top or the base of the capacitor or it may sit at an awkward angle with the motherboard, so compare the various capacitors in your computer in terms of and placement. Additionally, a bad capacitor may have a funny smell or it may have a brownish residue leaking from the top or the base. b> Prevention b> Manufacturers claim that capacitors may go bad because a computer is not receiving enough power from a power supply, because of an overclocked processor or because a computer is operating in an environment with too much heat or humidity. However, some capacitors prematurely fail due to faulty work on the part of the manufacturer. If you have a bad capacitor be sure to do research as to the lifespan of other products made by your manufacturer.

Yes. Got RAM? The heatsink fan? How about a video card, and all the 12V (4 to 6 pin) connectors? All plugged in suitably?

The machine is listed on Emachine's support site as not being Windows 7 compatible.
You most likely would be able to load and run Windows 7 on the machine but you may have issues with some devices not working properly and could have a great difficulty locating drivers for some of the devices.
I would carefully consider this if you do decide to upgrade to Windows 7.
You may also want to check on the link below to ensure any external device you have (printer,scanner,etc) and any old software are compatible with Windows 7.

Testimonial: "many thanks!"
same thing happened to me with this machine -- actually, two power outages. I thought I was protected, as I run UPS and the machine should have hibernated (I know it did the first time). At any rate, after the first failure, the clock wouldn't run right, and after the second, the exact thing you describe happened.
I was within days of losing the warranty, and sent the box back. Cost $27 to ship, insured. They replaced motherboard and reformatted hard drive. It works fine now. 90-day warranty on the repair.
In short, your motherboard is toast.
