It sounds like a motherboard issue.
Six of our 270s have experienced this exact problem.
A replacement motherboard would correct the issue.

Make sure your computer is off then: 1- keep press and release "F8" button on your keyboard while turning your computer on. 2- you should see a black screen with some text on it. choos "Safe Mode" If you still can't see anything you need to make sure all cables are connected and are not damaged. If still have problem you need to open your computer case and fasten all cables and cards because when your son pulled the cabel this could moved your computer case unsafely and loosen the cables inside. If you still have problem this means your hard drive has been damaged due to sudden movement while it was operating.(even if it's not operating sudden movement coulds damaged the hard drive). you need to buy a hard drive and install a fresh window on it but if you can not do it. Find your local computer repair shop (Yellow page- Thumson Local ...) Good Luck Please let me know of your progress and leave me a good feedback. Kind Regards

Sounds like its the video output from your computer. Try installing a new video card.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

I was playing solitaire on our home PC and the power went off and the screen went black. Before it went black it said "no input signal go to power save" Everytime I try to turn the computer on...

It means that your monitor is not getting a signal from your PC. Your monitor is fine though. You will need to plug the video cable from your monitor into the onboard video if you are using a graphics card. If you are not using a graphics card then you will probebly need to get a PC technition to diagnose the problem with your motherboard.

Hi , i turned on my desktop & left it so after a while the screen saver started as usuall but withing secs the monitor went blank and blinking as if there is no signal so i checked the signal cable...

your pc probably freezed up for some reason, you can turn it off by keep pressing the power button. After a few seconds it should power down. reboot the computer, he wil probably start a checkdisk and afterwards your computer should be fine. backup your pc asap, and try to find the reason for the freeze (recently installed new drivers/software?)

Abrupt loss of signal to monitor.

May be your Video card. Try a different monitor to see if it is working. If not you may need a new video card.

No power. will not turn on.

Hello

On/off switches do go bad. The "No Signal" is more likely caused by a loose cable, cable or electronic failure. Generally the refusal to turn on or slow turn on is caused by capacitors on the power supply board which have changed value. Take it to a local repair person or see my website: www.micromendllc.com

Good Luck
