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?
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?
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.
