I recently display snow to see distant ripple close is particularly clear how to deal with this is especially apparent in dark background they say behind the card and host off to see that when there is no signal no snow ripple where this problem in general ~ ~ ~ ~
One: VGA line contact bad or VGA line aging, two, adapter aging (that is the small box of DC power), with poor load capacity or filtering change. Three scan control panel is bad
Most of the power supply, electrolytic capacitor on the high voltage problems, need to be replaced.
Snow ripple, which is interference, generally speaking, snow ripple has the following possibilities.1, the signal line interference, from the chassis to link the computer's signal line, if it is too bad, it is very likely to cause interference, it is recommended to buy a magnetic ring of the signal line, magnetic ring can reduce interference.2, strong electricity interference, you have a larger power near the display of household appliances, high-power appliances from the display is relatively near, it may cause interference.3. display internal drive motherboard failure, such as a component oxidation caused by such reasons, this situation is more trouble, completely solve the need to replace the motherboard.
If the graphics card and monitor are not bad, only the quality of the display line is not good or aging, first change the display line to see!!!
No problem! Or you display the magnetized! There is your good butt in the back of the chassis is connected to the display line! Or open the chassis by press the card! There may be the display behind the wire are likely to loose!.. The general situation is not serious repair it dozens of pieces of 1 hundred pieces can be... Can you repair it yourself or you'll mend it?... Early repair, cheap and so serious, repair on the expensive ~ relationship. You didn't say that earlier.. Probably because your monitor interface is loose and the current is unstable. It's getting a little aging. It is estimated that some of the components in the board are out of contact. There may also be some dampness
