Emachine 180 Thanks for that. There are no sounds/bleeps coming from the machine. The power supply was plugged into a surge protector but its also been tried without. Still no joy :O(

No sounds or beeps rules out the hard drive, at this point it's either the power supply, motherboard, or cpu. Have you tried the power supply in a different machine? Also, eyeball the motherboard, specifically the capacitors, look for any that have bulges on the top.

depend on where the surge is. from power line, then most likely your psu is fried. if it comes from the modem/telephone line then probably your motherboard is fried.

No power cannot turn on


Suggest you check the simple stuff first.

Not checking is akin to a car that won't start, and tearing apart the entire fuel system, only to find it was just out of gas.

1) Make sure the receptacle the surge protector is plugged into, has power. Surge protector Power On light should be lit.

2) Check THE receptacle in the surge protector, that the computer itself, is plugged into.
Have had a number of expense surge protectors, where just THAT receptacle was bad.

("Hmmm, surge protector Power On LED light is lit. Monitor, printer, sound system, and router plugged into the surge protector has power. Should be good to go.

NOT!
Plug a table lamp, or similar device into THAT receptacle.
Make SURE it has power)

Surge protector, and receptacle in surge protector checks out?
Bypass the Power On switch.

See if the problem is a $5 Power On switch, or the Power Supply.

(Generic ATX Power On switch that I have found fits many computers,

http://www.directron.com/atxswitch.html

{The Power On switch, is located inside the plastic Power On button assembly}

This is information about computer Power Supply's,

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

This is a basic example of an SMPS, (Photo at upper right. You can click on the photo to enlarge), and info about.
(Switched-Mode Power Supply. The main type of power supply used in personal computers),

http://en.wikipedia.org/wiki/Switched-mode_power_supply

By bypassing the Power On switch, you will be able to determine if the problem is the switch, or Power Supply.

Bypassing the Power On switch turns the Power Supply on?
Bad Power On switch.

Bypassing the Power On switch does Not turn the Power Supply on?
Bad Power Supply.

A jumper wire is used on the 20, or 24-pin ATX main power cable.
The jumper wire goes to the Soft Power On, (PS_ON. Green in color), to ANY Ground wire.
(ALL Black wires are Ground wires)
A MOMENTARY contact is used.

(Example of a 24-pin ATX main power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24 )

In order to guide you in this procedure, I need to know the computer manufacturer name, and Model Number.

On a desktop computer this will be located on the Back of the computer tower, (Next to the Windows product key), or up on the side of the tower.
Some models have it where there is a door you open in the front, and the product number, or model number is located there.

My desktop dont come on


1) Check THE receptacle in the surge protector the computer is plugged into.

I have found more than once that One bad receptacle in the surge protector is bad.

"Hmmm, surge protector power on light is lit." "Monitor has power, amp for the speakers has power, and the router has power."
All plugged in to the same surge protector.

Tried a table lamp into the receptacle the computer was plugged into, Nothing.
Replace surge protector.

2) Bypass the Soft Power On of the Power Supply, and see if the problem is the Power On switch, or the Power Supply.

If you bypass the Soft Power On of the Power Supply, and the Power Supply comes on, the problem is a bad Power On switch.

If you bypass the Soft Power On of the Power Supply, and the Power Supply does Not come on, the problem is the Power Supply.

If you wish to know how to perform this simple test, just state so in a Comment.

My emachine T2958 will not turn on but it did work for about 3 weeks and one day it just quit working. I opened it up and plugged it in and a green light came on and is making a buzzing noise. Is it the...


It sounds like a power supply failure. Do you plug it straight into the walll or into a surge protector. If you are close to a best buy, go to geek squad they will diagnose the issue for free but the fix is real simple. Let's just put it this way there are a few things that protect the motherboard from getting fried. If it is the PSU u are looking at roughly 40-60 dollars and it is a matter of 6 connections. Give me a shout if you need more help

Power surge


You will need either a digital multimeter or a Power supply tester(recommended) for a couple of dollars on ebay the power supply tester is much easier than trying to test it yourself.

you can get one here

http://cgi.ebay.com/PC-20-24-Pin-PSU-ATX-SATA-HD-Power-Supply-Tester-Tool-B_W0QQitemZ300260901275QQcmdZViewItemQQptZPCA_UPS?hash=item300260901275&_trksid=p3286.c0.m14&_trkparms=72%3A1234|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50

This is a link to the tester that I own.

I would suggest a better method of surge protection. Go to radio shack and spend about 50-75 bucks on a good surge protector.

Emachine 180 (bought 2004)


I have this type of computer (just sitting around , not for my main computer) and I had a smilar problem. I took it to a guy I know (who owns a computer repiar shop) an he said the motherboards on this model go haywire about four years after initial power-up. On mine, it caused the power supply to blow-up (literally) and blew out most components. (Floppy drive, Sound card, USB ports, Keyboar/mouse plugs)

I really don't know if What he said is true, but I replaced the power supply, and now it works fine.

Emachine with XP home edition doesn't start


Hi hearalso, down to the basic's. Replace power cord.
No help there than, remove the case's side panel to expose the motherboard. (Normally it is the left side panel while facing the front of the PC.)
Look closely for a small (green in color) led light. The power cord must be connected to the PC & connected to you're power strip but do not press the power on button on the PC.
The green led tell's you the board is receiving 5volts. Check all connections. Un-plug & reconnect every data & power connector in your PC. (Double check). There is a fuse inside your power supply that may have blown. Check you're manual page, Approva Statements B-1. Fuse Warning Instruction Caution.
Check fuse in power supply. (Unplug power cord before opening).
If you can not power up the PC after all of the above than if possible, swap out the power supply.
Replacing the power supply is the last step.

If you have more questions, feel free to ask.
Good Luck!

Emachines shuts down by itself all the time


There are a lot of problems with Emachines as far as motherboards go. Since you've already replaced the power supply, it's safe to say that it's not causing your issue.

Since you seem comfortable with the inside of your machine, go ahead and take out all unnecessary components. If you've left your machine the way it was since you've bought it, start with the modem card that's in the bottom PCI slot. Often, those can cause issues with the computer not starting up, staying on, etc.

Also ensure that the machine is free of dust, and that all cables and connections are secure. Try not to let things float freely, and make sure you're plugging the machine into a surge protector, and not directly into the wall.
