New computer, seems to be working fine but then the screen goes all grey-like. It looks almost like a pattern you would pick as a background. You can't shut it down or put to sleep. If you hit the menu button on the monitor it brings up the menu and is readable but it is like it's not getting any signal from the computer. You have to completely power down and restart but then it works fine! I have tried taking cables off and on, changed monitor cables etc. Any ideas?

Re:
It sounds like a problem with your computer not the monitor. If you have a spare monitor you should try plugging it into the computer to see if the problem still happens to be sure it isn't your monitor. If it still happens you might want to check to be sure your video card isn't over heating. New computers can have problems from the start but that is why companies offer warranties. Call Gateway support and have them walk you through some troubleshooting.

Hi, please remove the vga cable from the back of the monitor, make sure that you don't remove the power cable from the back of your monitor. If you see the power on self test or any other pattern of colors in the screen, if the screen display remains white or goes black it would mean that the monitor has gone bad.
See if the set has some sort of reset button. If none do a hard reset on monitor to hopefully clear the cobwebs in monitor electronics and see what happens.
i have the same issue before with my DELL 2001FP, I replace the 3 capacitor on the board that look like defective because the top is look like swolen, it should be flat. I replace it with the same value and now the it works better.
if the monitor works fine on your laptop, the problem definitely is at the computer, possibly with the video card (if it is using one). it could have loose connection, or parts might have damages. it seems the problem is intermittent so electronic component of the video card could have parts partially damages or leaky components. if your still using the motherboards built in video out put, try installing a new video card.
1.What I need you to test is...When laptop monitor go grey try plug external monitor and see that it work fine or not ??
2.Incase it work fine try to give a little tap behinde the laptop monitor and see that any changes...keep try and harder and see
3.Incase if you gave a hard tap also and its still the same but external monitor work fine then....I think you have problem with your LCD monitor coz there are chips that control the LCD crystal and maybe when it goes hot it behave this way....in this case you can't change the chip...you have to change the LCD.
takecare.
This could be a computer or monitor problem. The reason that display shows up is because the monitor is not getting a power good signal from the computer. If a monitor doesn't get a power good signal it goes into test mode. It could be the monitor has a fault that is not allowing it to detect the computer, or the video card or computer itself isn't functioning properly. If you can, hook the monitor to a computer that you know is working properly. This will tell for sure if it is the monitor or not, and eliminate that possiblity. Then you will know if it is the monitor or computer. If the computer is the problem you'll need more help troubleshooting it.
First of all I would check your video card. Do you have another monitor that works fine? If so I would hook the good monitor to your video card and see if you are getting a signal. If you still do not have a signal in the good monitor there is something wrong with your connection on your video card. Check the connector on your video card if it wiggles alot then it has come loose from the card. Best option here is to buy a new video card. If you feel that the connector is seated flush and does not move. Then you might want to look at two things. Either your monitor is not working properly or there maybe a piece of hardware that has come loose or unseated in your computer case. Try this and if you have problems feel free to contact me.
