Why is my monitor glitching?
My screen keeps glitching on me and I want to know is something going to crash on this computer. What could the problem be.

Most often, screen glitches are due to one of three reasons, if they are monitor related.
1.) Loose or bad cabling between the monitor and the PC, or power cord and the wall.
2.) Dirt inside monitor causing arcing of the high voltage circuitry.
3.) Intermittent circuitry inside the monitor.
If the glitches are video card related, the can be:
1.) Loose video card.
2.) Intermittent connection at the card connector.
3.) Bad video card.
If the problem is PC related, it is probably the power supply However, this would tend to affect more than just the video.
Monitors are not user serviceable Don't go poking around inside Even if a monitor has been unplugged for a long period of time, capacitive effects can cause lethal voltages to be present.
My suggestion is, make sure the cables are well installed Employ the screws that hold the connectors together Make sure the cables are not pulled taught Monitor extension cables are available for difficult installation circumstances.
Back up your data It's possible something catastrophic may occur at any time with any PC Regularly backing-up data is a difficult lesson to learn the hard way.
If the monitor keeps glitching, try an old spare or a borrowed monitor, or else just replace it entirely Monitor prices are so low these days, the pleasure of a new unit outweighs the price in most circumstances.
