Having problems with your Computer Monitors ?

Computer display jumbled and unreadable

\015 Months ago, the desktop monitor would show up a jumbled, shaky, fuzzy screen upon startup. If we restarted, it would usually clear up. As time went on, it would need to be restarted several times before it would clear up. Now, it won't clear up! The display is jumbled, big blocks of color, shaky, lines through it, fuzzy, just unreadable. Sometimes it blinks on and off, and sometimes after being left on a while, you can hear it's still on, but the screen is blank. Is this a video card problem, or is the computer just shot? It is about 8 years old.\015

Answers :

From what you describe, I'd suspect the Graphics processor, or even the motherboard as a source of the problem if the monitor works on a different system normally (Best way to check the monitor is a known good video source)

\015\012If it is the system, and the system is 8 years old, I'd recommend replacing the system rather than attempting to fix it. Trying to fix GOOD parts for an obsolete system is difficult at bst and oftern can be expensive. Often you can find a low end NEW system (One that is like 20 times faster than the failing system) for less than $300
Start with the simplest (replug/reset cable, degauss, electrical interference) and move incrementally to the hardest (driver issues, motherboard, etc)

Hi, I got a serious problem with my PC. The PC was working as "normal", but the monitor display was not "perfect" :-). So I went to control panel->display->setting->advanced->monitor.
