So I got a new 2800+ (2.0). My first motherboard told me it was a 1900+ (1.2). Come to find out my motherboard was not compatible with a higher FSB speed and would not cooperated with my new cpu. I got a new motherboard and switch my CPU clock from 133 to 200 and now my monitor won't turn on. It acts like it's going through the startup but doesn't. My harddrive light stays on like it's working and doesn't turn off. It checks my disk drives too. My monitor just doesn't switch on and I can't see anything to reverse my settings.
