    do you get any type of display on screen? it sounds like there is a short somewhere and its overloading the power supply, if your gettin something on screen your cpu could be overheating or the power supply could be near the end of its life

Psu wont turn on


Test the PSU. Unplug it from the motherboard and then with nothing connected, short the green wire to any ground (usually a black) using a paperclip and it should come on and stay on if the problem was with the motherboard/computer but if it shuts down, then you know the problem is the PSU itself.

If the PSU stays on under no load, then one possibility is you had too much connected to it and it shut down as a protective feature. The Bios would not beep if the PSU is shutting itself down. Also make sure you have the internal speaker connected. It's possible you just can't hear the beep because there is no speaker connected or it may be connected to the wrong place.

Don't throw away a defective power supply. It is worth a couple bucks as parts for an electronics enthusiast. Keep it out of the landfill.

When I turn on my computer it runs for a couple of seconds and then stops.


Unplug everything inside the computer, except the motherboard and the front panel power on switch. Power up the computer. If the PS fan continues to run, (power supply doesn't shut down)and the CPU fan runs, then power off the unit and reinstall each device, one at a time, turn the power supply on after each device is installed (and off, before installing the next device).
You can not easily start the power supply if it is not connected to the cpu motherboard.
If the power supply shuts down with only the motherboard attached, then you will need either another power supply, to test the MB, or another MB to test the power supply.

Some power supplies have an independent switch to turn on the power supply before you can power up the computer from the front. Does yours have a switch on the back?

I was running the program "windon Defender" on it and walked away. When I returned the computer was off and wasn't turn back on.


The Windows Defender Application is the Antivirus Software which will be pre-installed with the Windows Operating System(Windows Vista, Windows 7).
The Computer will always Shut down after any Windows Updates or any Operating System Updates are downloaded and installed.
If you are connected to the Internet and running Windows Defender, the Computer will automatically download the Updates for the Windows Defender Application.
Once the Updates are downloaded and installed, the Computer will prompt for a shut down.
The count down will be for 10 seconds.
After 10 seconds, the Computer will install the downloaded Updates and shut down.
This might be the reason for the Computer to shut down while using the Windows Defender.

If the Computer still shuts down randomly, the issue might be due to overheating.
All the Processors in Notebooks are designed to shut down automatically, if there is any overheating issues.
The overheating issue mainly occurs due to the malfunction of the Cooling fan.
If the Computer shuts down frequently, the issue might be due to the above factors.
It would be better to get the Unit examined at the Service Center.

Hello,

I would ask the customer a few questions:

1. Do you have the computer connected to a power adaptor or is it a voltage switching pc?

2. Has the pc always done this? If not, have you changed any power setting in the control panel? (Or have the checked the power setting.)

3. When was the last time the pc shut down properly? Maybe the pc is trying to install updates and need time to finish the install. (If when powering off the pc you see a shield over the power icon from the start menu, let the pc run its course and it should power on/off correctly.)

Good Luck

Tower problems


You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this


Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say

My monitor turns itself on and off with no prompting


Go into the control panel and check the system settings. You might have it set to turn the monitor off after a low number of seconds of use. If you have it set for 30 seconds, if you don't use the keyboard or mouse for 30 seconds, the monitor will shut off. When you start to use it again, it will come back on.
