Monitor Shows pixelated colors then flashes no input and turnsoff
Ok So I'm playin a game online, first my computer beeps once, then the screen looks like it has colors kind of melting into in until it all turns into big pixelled squares. I had sound and dont believe it locked up but I cant really tell to be honest. I powered down the computer and now everytime I start it my monitor gives me a crazy color show then my monitor flashes no input and turns off, after 10 seconds I get the crazy colors again then off again, this repeats over and over again until I turn off the computer. Im hoping its a monitor or Video Card thing I just have if theres a way I could get a definite answer as to which one.

Once the monitor shows "no input", indeed the mouse and keyboard are pretty useless, even if the are working, as you cannot see they are working. If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.
Unfortunatly you do have dead pixels, but you cant fix them. Lots of lcd displays have them, some are more noticable than others, it dosent mean your lcd monitor is going to fail soon or anything like that, even brand new lcd monitors have dead pixels it is a comman anoying problem with them.
That "red white green and blue" block is a color pattern tester. that means the monitor is on, but is not receiving a signal, so its running tests. If your monitor has Digital input and VGA input, you may just need to switch inputs. Look for 1 or VGA if youre using the blue hook up. look for 2 or digital or dvi if youre using the larger white hook up. Some monitors also have 'auto detect'. If you are in "auto detect' bbut the color box is still there, then your monitor is not receiving video signal from the computer. It could indicate a bad cable or no signal being sent by the machine. If you try another monitor, you can see if the machine is working. I would try a monitor setting for VGA-1 first, since thats most common.
Take a look at the back of the monitor there must be a cable which is connected at the back of your computer tower.
If you take a look at the back of your computer tower you will see that cable has a big plug with two screws on the top of it. It could be blue in color or may be grey. ( The name of that cable is Video cable )
Now what you have to do is to take that cable out of the computer. Now switch on the computer.
If you see a message on the screen saying " NO INPUT SIGNAL " :- That means your monitor is fine. If it does not shows that. Then your monitor is bad.
Remember the power cable of the monitor should be connected while doing the above steps.
Now incase you can see the "NO INPUT SIGNAL " message on the screen. Even then the problem persist.
It might be possible that the Video cable has gone bad. You need to consult a hardware technician for your monitor.
Your Monitor is not connected properly http://www.microsoft.com/windowsxp/using/networking/setup/wireless.mspx
Connecting Your Monitor 1. Turn off your computer and unplug the power cord. 2. Connect the white connector end of the DVI cable attached on the monitor to the connectors on the computer. 3. Connect the USB cable that was included with your monitor to the computer and the upstream USB connector on the monitor. Once this cable is connected to the computer and the monitor, you can use the USB downstream on the monitor. 4. Connect any USB devices. 5. Connect the power cord. 6. Turn on your monitor and computer. If you do not see an image, see Troubleshooting Your Monitor.
NOTE: The Monitor will display full screen in White, Black, Red, Green and Blue color rolling pattern on screen if the DVI cable is not connected. This self test pattern will be displayed continually when Monitor detects that DVI cable from Monitor to PC is not connected.
* Check connection integrity at both ends of the video cable. * Ensure the monitor and computer are plugged in to a working electrical outlet. * Ensure power button is depressed fully.
That is so crazy. You say you previously was able to see the POST screen and now you can't? You say you switched monitors and card outputs to no avail? Is the card an ATI with an aux Molex power connector? Is the puter actually going into standby or hibernation? Have a boot disk? or a PE? How about a Linux self-install distibution CD. Just kidding about that last one. Not really, you can see if the puter does respond.
Don't rule out a faulty power supply. Video card fail is usually one long, two short beeps at POST. or 8 short.
What indication do you have that the system is on?
Do you have any LEDs active on the front of the system box?
Also, your monitor should indicate whether you are receiving video sync signals from the system by changing LEDs or the color of one and possibly give you an on-screen notice that it is or isn't getting input.
If you disconnect the video cable from the back of the system box, most monitors will post a small notice on the screen that it is working but not getting any input.
