PSU may have damaged the motherboard with transient power surges. The replacement of PSU, video card, monitor, and monitor cable reduce this to the motherboard.

Did you try changing the Refresh Rate?

Does the monitor do it on another system?

Never mind. Just noticed you tried a different monitor.

any monitor will seem to flicker when the refresh rate os lower than 70 or 80 Hz, but this  seems related to power, i would get a reliable Power Supply and that should take care of some of it at least, then try to change the refresh rate.

Good Luck,

Thank you for your help.

I have not tried ghanging the refresh rate , What woud you suggest I change it to?
I bought a new power supply. It had 240 and I replaced it with a new  300 PSU.

There were times when it appeared that a thin layer of water was sliding down the screen. Ive seen screesavers like this but more intense.

Her monitor flickers. When I had it at my house with my monitor it did the water slide look. I messed around with a lot of computers. Never saw this.

That depends on what the monitor will handle, but 75MHz is usually a safe bet.
