Idiot me screwed up my computer majorly just the other day. For some reason I went into the setup menu (hit delete key during start-up) just to look around in the advanced settings. First, I think I changed my system performance from optimal to aggressive. Then I think I changed the FSB from 100 to 200. And finally I saw a TV mode support option that was at disable and I changed it to either NTSC-M or NTSC-J. I did that because I thought since I was hooking up to my NTSC TV that's what it needed to be set to. Then it all went haywire. Nothing even shows on the monitor. Actually, my monitor does not even detece being sent a signal. The little green light stays at the amber/orangish color, which means there is not a signal. So what in the hell do I do to get my computer back up in running? Would formatting my harddrive help anything? I just built this computer a few months ago and have an "all-in-one" mother board. It's the WinFast K7 NCR18G-Pro socket A mobo by Leadtek. I also am using an Athlon XP 2000+ processor. Everything was purchased at Newegg.com. Please help me!
