Okay I'm running windows vista premium, 64bit, with a NVIDIA GeForce 9800 GT video card. My monitor is a Generic PnP Monitor, LCD.
Two days ago my sister brought it to my attention that my computer monitor was flickering. Not back and forth between black and fine, all the hookups are fine, nothing loose, nothing broke, everything externally is fine.
The flickering is more of a rolling flicker, and can only really be seen on the darker parts of the screen, but it's affection the whole computer. I tried changing the refresh rate to a higher rate, but it didn't help, I tried resetting the monitor to default, but for one reason or another it became entirely too bright and I had to work for 30min to get it back to a normal look.
There was also a point when I reset the monitor to defaults that it suddenly turned green, and when I turned off the monitor and back on it was gone. It did it twice, but not again after that.
