When I first turn the system on in the morning, everything is just fine. As day progresses, and after turning system on and off, monitor starts getting thin colored lines immediately following the Windows boot screen. Problem looks like it clears as I get to applications, but as day goes on, with subsequent on/off cycles, start getting funky little color boxes immediately following Windows boot screen. Symptoms do not clear as rapidly with applications the later in the day process is repeated. Most recent symptom is that it looks like I am losing screen pixels.
I've run Norton antivirus and have found nothing.
Does any of this sound familiar to anybody?
Thanks for the help.

Hello friend, Please i think you card is not acceptable by the system, or have you checked another card on the system to see if it displays the same thing. And when you remove the card the system boots normal without any error. So check on the card make a change on it.
This is usually caused by the video card doens't have enough power or is degraded, the video cable is bad/poor.
Connect the monitor to another computer and verify that it isn't the monitor. If so, confirm that it is the monitor. Otherwise it is the video card.
If it is embedded video card, purchase/borrow another video card and install it. If you don't replace the card, you will have to disable the embedded video for the video card to work.
To determine if you have a faulty LCD screen or a faulty video card, connect an external monitor to the laptop's video port, power up the external monitor first the the laptop. The video output should automatically switch to the external monitor. If you get a normal image then the video card is OK, and the fault is with the LCD screen.
If you still get a bad image, then the fault could be a faulty video card or video RAM. Most laptops use part of the main RAM module for video RAM, try reseating the RAM modules and or test the RAM modules. If the RAM is OK then the fault is the video card.
The problem lies with your video card. The fact that it worked on your friends computer proves that it is not your monitor. Some motherboards have two video adapters. One on a video card and one on the motherboard. You need to open your PC case and see if you have one or two. If you have two then you can try the other one. Otherwise, replacing the video card will correct it. However, if the only video adapter is the one connected to your motherboard then the motherboard has to be replaced. If you have any questions let me know.

easy way to find out go to bestbuy and purchase a video card and install it if everything works out its the video card if not then its the monitor that went bad if its still under warranty send it back and get a replacement,
It only happens with your keyboard and mouse? or does it include your monitor too? if it does include you monitor then it is the video card. It is built in to your system and is causing the problem. I got the same issue before. My mouse doesn't work, keyboard won't respond, monitor is blank. I know its the video card. It is not typical for a server to respond that way but you need to replace the system or replace the video card...
Do the server has an onboard Video disable the video in the BIOS setup insert another PCI Video card and check for the display , IF the PCI display is up then there could be a problem with Onboard card.
I had the exact same problem!! Drove me crazy for days. Couldn't find any answers online, contacted Gateway tech support and they told me my warranty was expired but they'd be happy to discuss my issue for $2 per minute. Gateway can **** it!!
At first I thought the problem might be a malfunctioning NVIDIA card, a problem with my DVI cable, or the monitor itself. But, after turning off the computer, unplugging the DVI cable, replugging the DVI cable and restarting the computer, I noticed I could get the firmware flash screen to show, including the BIOS menu boot and the Gateway system reinstall screen to show. As soon as the Windows flash logo would display, however, the monitor would drop out and display the dreaded "No Signal" error.
This indicated the problem was a software one and not hardware! The cable, monitor and video card were all working fine. Then I remembered that Windows installed its automatic update a few days prior. In fact...
THE PROBLEM TURNED OUT TO BE A WINDOWS UPDATE INSTALLED A FEW DAYS PRIOR.
After succesfully booting into safe mode (F8 during the flash/bootup screens), I went to Add or Remove programs in the control panel, clicked on the "Show Updates" box on the top, and uninstalled the Windows update from a few days prior to the occurance of the error. After a reboot the problem was solved.
I hope this will help anybody else struggling with this error!
