Come on, boots up, then shuts down 5 - 10 minutes later.

I have a T1400 emachine. I can turn it on, it boots up, runs for 5 - 10 minutes and then shuts down. I have to press the power button several times for it to come back on; however, with the same results. 5 - 10 minutes and then shuts off. If I shut it down before it has a chance to cut off, it will start up with no problem, one push on the power switch and on she comes. Am I correct in thinking it is just a power supply going bad? I have opened it up and cleaned out all the dust and both fans are working properly (one in computer and one on power supply. Any suggestions?

    This behavior is normally indicative of a heat problem. But you said the fans are running. Is the fan over the CPU running?

    If you've cleaned it out like you said, you could try to swap out the power supply--they really aren't all that expensive.

I recommend checking your power settings in the control panel, it should actually be under display settings. It may under those settings somehow be set to shutdown in 10 minutes. You can find the power settings, sleep mode, UPS, and hibernation under the "screensaver" settings of display. Look for a tab on the screensaver settings that says"power settings".

Check your power options make sure you don't have hibernation enabled, its in the system control panel. try booting from a linux live cd like Ubuntu which you can download for free. If it runs fine under linux, its a windows problem, if it keeps shutting down its a hardware problem. Could be bad ram, or CPU overheating.

E machine monitor turns itself off and on


The same thing happened to me today. I was just sitting in my room then i hear a click and the cpu is on it stays on for a while then cuts off. It then cuts on and off with few seconds in between. It then stays in that way cutting and off for about a minite or two and then cuts off completely. A few minutes later it starts again. Also in the time it its off it will not turn on by pressing the power button. Sometimes it completly boots up by itself and then shuts itself down. If I shut it down manually while its on it'll turn itself on immeditaly after. What's going on! Will the warranty cover it? Do I need a new computer?

Starts up fine after couple of minutes its shut


Your system sounds like it is either overheating or has a bad power supply If you remove the side panel on you desktop and look at the fan above the processor, it should be running at all times. If not your fan has blown and you must replace it. Please find out what version processor you have before making a purchase, as there are many different types of processors and fans.

Another issue could be poor circulation or inadequate ventilation. Hope this helps.

Good Luck!

PC shuts down. When you turn on the pc it shuts


try to change the source, that should solve the problem. But before try reset CMOS. (if you don`t know how to do it by jumper simple remove the battery from the mainboard for 5 minutes and then plug it back on..and after that turn on your computer and press F1 for default settings)

Emachine T6216 Automatically Shuts down


Hi MIchael,

Before I start replacing hardware, I would boot to safemode, and let it run that way to see of the problem repeats. In Safemode, a lot of drivers and software that may be causing the problem won't start up.

As soon as your start your machine, tap the F8 key about twice a second. This should bring up a screen with several options. Select Safemode. You will get some warning, so just click yes on those. Your screen will look really strange, since your video drivers won't install. Let it run like that for a few hours. BTW, you won't have internet.
If that still reboots, or shuts down, chance are good it a hardware issue. Might be your Heatsink on the cpu is too dirty to cool, but the techs you took it to should have cleaned that.
Get back with us, and post how that works please.
You can also right click on My Computer>Manage>Event Viewer and look thru the different catagories. Look for issues with red marks on them. To read them, just click on them. This may give you idea what is failing.
A issues that is random is hard to troubleshoot.
Good Luck!

Emachines wont boot


Bad capacitor(s) on the motherboard can cause this problem, corrupted BIOS maybe... try flashing BIOS.
Probably the CPU if your not getting any error code beeps on startup.. NO Processor for the BIOS instructions thus no Beeps !
