Hi, I'm using a P4 based PC. It has a Zebronics 845 motherboard. The motherboard has intel graphics extreme. I changed the screen colors to high and from then the monitor goes off when its boots into xp. The refresh rate of the high color, i selected is more than supported by my monitor. Now i can't revert back to normal colors.. In safe-mode i can only disable the vga drivers. Re-installing vga drivers ain't helping either. Anyone know a way to revert back to default?
