Hi,
My monitor screen flickers a lot of late.i have changed the refresh rate to 80, but it dint work.My computer runs on 512 Mb Ram,P-IV processor and asus motherboard.any movement on screen triggers the flicker. Even a simple mouse movement as well. It becomes worse when i try to use photoshop or watch movies.I have checked the cables and wires as well, everything is fine.

It could be either try swaping the monitor if you can first but i would have to agree that it is either the monitor or the graphics card.

One way or another you need to prove whether it's the monitor or the computer doing it.

If you can't get hold of a monitor to temporarily substitute, can you try your monitor on another computer? e.g. if a friend has a laptop with an auxiliary VGA connector, they could hook your monitor up as a secondary screen & see if it still flickers.

Try this - Turn the monitor and computer and speakers off.
Then turn on only the monitor. You should get a test pattern or "Monitor disconnected" "no input" or something.
See if it is fine then.

If so, turn the monitor off. Turn the speakers on and then turn the monitor on.
If it flickers then the speakers are probably too close and causing interference.

This would eliminate the computer.

In the beginning there was the command line.

Don't forget some "oblivious" items:

Flakey AC power connection to the monitor... wiggle everything and see if you can make a significant change in behavior, either far better or far worse.

1) bad power cord (swap it for another one)

2) bad outlet 'hole' in power strip/surge protector (try another one)

3) bad outlet in wall (wiggle plug, but best check is try a two-prong plug from something that you know plugs in "firmly" elsewhere. If it slides in with very little force compared to what you know is good, replace it. I've had experience with this, especially with the (used to be) 59 cheapo outlets sold by Home Despot.)

The reason I bring this up:

I'm guessing that the OP is probably still running a CRT monitor due to the age of his computer (512 megs RAM and running PhotoShop???). I'm guessing somewhere between '99 and '03 from "P4" and "512". The generation of CRT monitors out at that time could also have "bad caps" (see http://www.badcaps.net/pages.php?vid=4)

What's interesting is that bad caps in a monitor may only show up on short power glitches caused by the above problems (and the symptoms are what the OP has). Even though the pooter may live past the same glitch (even with bad caps in the power supply), is because the power loads are totally different.

So it's possibly a "double whammy". I've seen numerous problems with more than one true fault. It's like archaeology, you find one just to uncover another buried under it.

In case you hadn't guessed, I've been both an electrician and an electronic tech (sometimes both at the same time) for years. Two phrases best describe my background; "DC to Daylight", and "Widebanders Do It Till Their Gigahertz".
