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.

Gateway a computer desktop has power but nothing on screen the computer doesn't have a tower


1) Computer doesn't have a tower? Means it is a 'pancake style' of desktop computer. A flat model.

2) No signal on monitor screen?
Good.
At least we know the monitor is good.

Problem is monitor cable, IF separate cable; or computer.

Computer isn't sending a video signal.
No Signal, Power Saver Mode, etc.

If an older CRT type monitor, (Looks like a small TV), and monitor cable is not detachable; use a known to be working monitor, and monitor cable.

If a separate monitor cable, use a monitor cable from a working computer, for a temporary test unit.
Put it back when deemed monitor cable is the problem.

Logic at this point, would deem something is wrong with the graphics chipset.
Whether mounted directly to motherboard, (Integrated), or a separate graphics adapter card. (Graphics/Video Card)

However, computer could be dirty inside, or have a bad Power Supply.

LED's (lights) light up? Maybe fans spin?
Means nothing.

1) If ALL of the Light Emitting Diodes were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 130 Watts of power.
Just depends on what Processor it is.

Older desktop computer?
Ummm, 35 to 40 Watts.

That is why LED's can light, and maybe fans spin, but no computer.
NOT enough power to turn the Processor on.

Computer needs to be CLEAN on the inside. Inside of Power Supply too, as well as possible.

Proper method to do this procedure, post back in Comment if you need guidance.

Also remove ALL Ram Memory modules, and clean gold plated contact pins on bottom; with pencil eraser.
Reinstall. Make SURE they are seated in tight, and Lock 'ears' are locked in place.

Post in a Comment, as to the model number.
Example, DX4300-05. Should be on back of computer.

Both leds are on


Have you checked the cable and reseated it, check for bent pins in the connectors. Perhaps the Graphics card/adapter is gone.

Acer ASpire M1100 shows No Signal on monitor


Any time a monitor says "no signal" that message is originating from the monitor itself, and not from the computer. A monitor in a room by itself with no computer will say "no signal" for a brief time, if it is turned on. So, if you have tried other monitors also with no luck, then the problem is either the video adapter of the computer, or something that is keeping the computer from booting in the first place (power supply, hard drive, memory, motherboard). A power supply can be tested with an inexpensive tool. Everything else needs either a swap out with a known good stand-in, or else an expensive tool to know if it works.Does the fan come on when you turn the computer on? If so, maybe more likely to be the motherboard, hard disk, or memory. If not, more likely to be the power supply.

Turns on but nothing happens, no signal to monitor, mouse or keyboard. Fan is on.


Bad Power Supply.
Weak voltage power rail.

Enough power to light LED lights, and spin fans, but Not enough power to turn the Processor on.

1) ALL of the LED lights on at one time, use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can use 51 to 125 Watts.
Just depends on what Processor it is.

No Processor operating, No computer.
No computer operating, No signal on the monitor.
NO video signal to the monitor from the computer)

Need guidance in replacing your Power Supply, please state in a Comment.
Need guidance in choosing a correct Power Supply, I would be happy to give a few references for you to look at.

(Do you have a KNOWN to be good, Compatible power supply around that you can use for a test?
Perhaps in some computer tucked away in the closet, etc.
Maybe a relative or friend has upgraded to a better computer, and has an unused one you could borrow the Power Supply from)

No beep


What indication do you have that the system is on?
Do you have any LEDs active on the front of the system box?

Also, your monitor should indicate whether you are receiving video sync signals from the system by changing LEDs or the color of one and possibly give you an on-screen notice that it is or isn't getting input.

If you disconnect the video cable from the back of the system box, most monitors will post a small notice on the screen that it is working but not getting any input.

Computer turns on, but there is no display on monitor.


The builtin video card is probably bad. Yes, you can get a PCI video card.
