I have the same T3256 emachine. It starts up then quickly shuts down. Sometimes it'll run for a few minutes and then shut down. I too replaced the power supply for 80 bucks with the same result. Then I thought, the switch is not a toggle on/off switch, its a push in, spring loaded type. I opened the front of the machine, removed the switch from the snal clips, open the switch (boy its small) vacuumed all the dust out when i replaced the power supply, and simply claned the internals of he switch. bw careful, there's a small spring that is easy to lose! I just did the cleanup thing again today. the firs cleaning lasted 6 months and it didnt start for nearly 4 years. So dont give up!! All I did was just scrape the contact wih a pointed knife until it was shiny again. Be sure to clean both sides.

I love eMachines , I have a nice nforce2 FIC board from tower T3395 but lets get to your problem

from what you've described , the computer powers on then shuts down quickly

that means a serious problem , my suggestion there is not to throw in the towel just yet

1. remove the cover and have a looin in there to see if it's all dirty

Dirt and Dust can cake up the CPU fan , and cause a thermal shutdown.

Heat is also an enemy.

2. make sure you blow it all out with a can of air or if you have no can of air
take off the CPU heat sink assemboly and wash it off , then stick it back on

and no you don't have to really worry about the little pad on some of the heat sinks
just scrape that junk off and use some thermal paste.

keep me posted , I wanna know what happens with this

Why does my computer fan suddenly run faster

As the cpu (central prossing unit also known as processor) heats up the fan will surge to cool it down. Nothing to worry about. If this helps you rate favorable.

Many times when a desktop is making a strange buzzing noise - it is due to a fan malfunction of some sort. Other reasons include a power supply that is faulty or possibly a bad internal speaker.

I would first check the fan(s) for the computer. Start by turning the computer off all of the way. Next, unplug the cords from the unit. You'll need to isolate just the computer tower itself. Next, you'll want to get some compressed air or a vaccuum and gently clean out the areas where the system case fan vents are. If you know how to open the case for your desktop, it wouldn't be a bad idea to make a quick visual check inside of the case for things that may be caught in the fans. Some desktops open via screws on the back plane, and some open with a pull tab/lever.

If cleaning out the dust doesn't resolve the buzzing noise - then you'll need to make sure that the noise is not part of the electronics. If you are hearing an actual electrical buzz and not a speaker or fan noise, then there is likely a larger problem with the computer. In that case - I would take the computer to a certified professional for diagnosis.

Another culprit of buzzing noise may be a CD/DVD drive with a disk stuck in it. Make sure that you have ejected the drive to ensure no disk is stuck in the drive.

I hope this information helps!

I have a refurbished ibm netvista. when i turn it on, the cpu fan will start to spin for a few seconds, then i'll hear a weak beep, then the fan will stop spinning (power off), then the fan will...

Remove the hard drive and RAM. See what it does. It should go into BIOS and complain. If it doesn't you have a motherboard issue as it won't POST.

Hi, Dell Studio 1535 cooler always starts, even if the system is not warm up. Plus mouse and keyboard work slowly. shut down computer, wait (2h.), but still the same. Checks the system load and temperature...

Try running the diagnostics on the computer to check if all the hardware is working fine. The diagnostics would take atleast 2 hrs to complete but would do a through check for the same. I have come accross the same issue on the said laptop and we have ended up replacing the system fan for the same.

To run the diagontics
1. Shut down the system
2. Press and hold the FN key on the keyboard and press the power button to start the system
3. Follow the screen prompts to run the diagnostics.

Note and post back any error codes if any

Thanks for using fixya

When i turn on computer screen is blank and the hard drive light is a solid amber for a minute then nothing....bad video card? Does same on two different monitors.

Video is on-board the motherboard on this model BUT you can buy (or borrow) a video card pretty cheap. When the computer starts up, do you hear any 'beeps', etc.? Might be something other than the video card...

Gateway One Fan Problem

Hi, there is a possibility that the fan is self is defective or power supply cannot supply the fan completely thats why when you turned it on you never hear it running. ICheck the fan connection if is properly connected then using a voltmeter check the voltage supply in the fan it should be +12V or you can replace the it with a reliable one so that you can determin if the fan is defective or not.
