Re: My computer shuts down after 3 secs

Try to separate the power cord of your monitor from your system or maybe if your using UPS(uninterrupted power supply) directly plug the UPS to the wall outlet. either you can use pretty voltage regulator to the regulate the AC power.
if not solve the problem try to examine the your system power supply.

How to shut down a computer?

1. Close any applications you have running, such as your email or instant messaging service, by clicking the "X" in the upper-right corner of each program page.

2. Left-click your mouse on the Start button, typically found in the bottom-left corner of your computer screen.

3. Highlight the option to "Shut Down" and left-click your mouse again to initiate the proper shutdown process.

4. Wait until your computer logs you off of any applications, your computer screen goes blank and the power light turns off before you turn off your monitor or close your laptop.

Computer wont boot Evo d510

Choose within this options with regards to your monitor: 1. You could replace your monitor with a new one. 2. Or you could send someone or send it to a technician to repair your monitor.
Boot Up Problem: 1. Try checking the Power Supply Unit (PSU) if it give out 12Voltz. If not you could replace it with new PSU. 2. Check the motherboard if there are some blown out Capacitors. If there is, send it to a technician to replace it. If none, replace your Processor. That is the defective. That causes the boot up problem.
On boot up screen. Of course it will not show a boot up screen because there is a problem on your monitor. And so, there is also a problem on your motherboard (Processor or Capacitor).
Hope this might help. Thanks.

My monitor shuts down after one second.

Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computermag-glass_10x10.gif has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.
  1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
  2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
  3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
  4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."

The display on my inspiron 6000 in jumpy at the bottom 1/3 of the screen. no evidence of any damage to case or screen. Just started with a black line and now jumps around and has white lines in the bottom....

Generally the problem is caused due bad LCD inverter cable. Kindly run the LCD diagnostics
How to Run diagnostics
1. Shut down the computer
2. Disconnect the AC adapter and Battery
3. Press the power button for 10 sec.
4. reconnect both AC adapter and battery
5. Press FN key+ power button
6. Follow the screen prompts.

If the LCD problem is shown in diagnostics your screen would have to be replaced.

Hmm... is still not working

Start your computer and tap the F8 key as soon as the computer begins to power-up. Keep tapping until you come to the Safe Mode screen. When the screen alerts you to the fact that you have chosen Safe Mode, click OK.

When you get to the desktop go to the control panel and launch System Properties. Go to Hardware and Device manager. Click the arrow next to the Display Adapter. Point at the adapter, right click and chooser Properties. Click the Driver Tab. Roll back the video driver to previous driver.

If indeed you have installed a new driver that is not compatible with your video card, then rolling it back to the original may very well take care of this problem.

Good luck!

My samsung monitor just turned off out of no where, but my computer seems to be still on, when i press the power button on my monitor it will turn on for 3 sec and turn back off, ive tried unplugging it...

Try another monitor (hopefully you can borrow one) - if it works, your monitor just went bad - they are very difficult to fix, just better to get another one.

BUT - PLEASE, don't do that till you try another monitor on your computer, to make sure that is the problem.
