Hi, I accidentally changed my monitor refresh rate to 100mhz and it was out of my monitor's refresh range (spec) but now the NT 4.0 didn't give me a chance to say, like after 10 seconds change back to the original setting if I don't click on the "Correct" button... so I"m kind of stuck here (and the screen keep showing "out of range"... how do I fix this problem? thanks!
