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.

When I turn on my gateway computer my monitor will turn on but will says "no signal RGB". is it my motherboard thats going bad?


If the monitor comes on with the Gateway logo and follows with no signal, the monitor is probably okay. If the computer seems to run with no display then I would suspect the video graphics card, but there are a lot of variables that I do not know. I suggest a computer repair store to check your system with an estimate.

No Picture


check all your cables leading from the computer to the monitor. the clicking is normal as the monitor looks for a signal from your computer, if it finds one it locks on. if it doesnt find a signal it clicks again going into standbye mode. the fact that its clicking shows its trying to find the signal.
the cables may be loose. the computer could have a setting too high for the monitors refresh rate.
do you see anything when the computer starts? or just a blank screen saying "no signal"?

Hd display gateway monitor is working but has no signal


Hi

If this is still under warranty, then Gateway (MPC) can repair this. Probably you homeowners insurance will pay for it. Make sure that the monitor data cable is plugged in correctly. Whenever we have storm my wife unplugs all the cables on the computer. Sometimes when we reconnect they get plugged into an inactive port, thus no pic. If none of these help then please contact me at micromend@live.com and we can discuss a repair plan.

Thanks

Screen goes off showing VGA with cable on the screen


This looks like a bad cable connection. Try using a new cable for the connection between the computer and monitor. If that does not work test you computer on another monitor to make sure you are getting signal output from the video card.Also check the monitor on another computer.This is to check and make sure the monitor is working properly.You can also try using a add on video card in the computer to see if you can use the monitor this way.If you still are having problems. You can use this web address to get customer from Gateway. http://support.gateway.com/s/PC/R/1013953/1013953nv.shtml. I hope this helps you with your problem.

Gateway laptop will not power on


Sounds like to me, that you do have power going to your computer(other wise your lights wouldnt be on), but that your hard drive is dead.

You can take it to a computer shop and have them replace your hard drive.

No Video Signal


Try resetting the bios. On the motherboard there is a battery that looks like a watch battery. Remove the battery, then replace it again. (make sure the computer is unplugged from the wall socket when you do this)

Does this work?
