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.

Hi, my Dell Vostro 200 monitor isn't working; when I boot up the light is blue and everything else seems to work but the monitor says 'Entering power save mode' or something and it shuts off. I can't get...


Your monitor is most likely fine. That message is the monitor telling you it's not getting any video signal from the computer.

If you're hearing all the sounds that go with a normal startup (usually a beep from the motherboard, then hard drive activity, finally the normal Windows startup sound through the speakers), and seeing that message, then you may have a monitor problem. You can try another monitor as a test.

The trouble is probably that the computer is turning on, but not actually starting up. This may be due to power supply, memory, processor or motherboard problems. Or one of the drives or expansion cards connected to the motherboard may be keeping the system from starting.

Make sure the memory modules are firmly seated in their sockets, and disconnect everything else but the power supply. If the motherboard, processor and memory are working, the system will start and you'll see something on the monitor. Then you can start reconnecting parts and see when the problem returns.

No signal on monitor


You might try switching the VGA cable if you haven't. If that doesn't work then I'd agree with you in saying the motherboard is likely fried.

New Motherboard & Processor not working


Usually this symptom has to do or with memory modules with problems or the VGA adapter (integrated) could be damaged. First try to reset the BIOS of *********** taking out the battery and using the reset jumpers informed in the Mother Board manual. Then put the battery and the jumpers back to the factory default position and try again.
If this doesn't work, try to plug the power cord to another 220V as the ground could cause this type of problems.
You can also try to install another VGA adapter to check if you receive the VGA signal in your monitor.
Hope it helps...
Please tell us about your progress.
Best regards

Your problem is either the processor or the motherboard. that is why your monitor is not getting any signal. first try to replace the processor because I suspect that this might be the problem as it has gotten overheated before. if there was a power problem with you power supply you monitor would not power up at all.

Computer won't boot up


Make sure that your power switch is connected to the correct pins on the motherboard. The LED you see lit may be the stand-by power indicator saying it has power and is waiting for the signal from the power switch.

No signal to monitor when booting.


(1) Remove memory from mother board and start the system if you happen to listen long beep then RAM is not working properly.
(2) Clean RAM conducting area on mother board with clean cotton cloth, put one peice of RAM and test and check the othe peice also, if working you could any sign display . Before doing all these check mother board any LED is glowing if so your SMPS is working after you turn on UPS.

(3) Check for all proper connection for all cables. Have you connected video cable of monitor to mother board VGA (it will not work because it is disabled as soon as you installed XFX GeForce 8800 GT), your viedo output only will come through XFX GeForce 8800 GT VGA port.

(4) If propelm persits Deassmble complete the system and reassmble & do n't connect HDD, DVD, floppy. Cehck with bare mother baord, processor, RAM (put one picese at a time) by connecting viedo cable of monitor
