Ok, I had this spare Gigabyte 7RVXP KT333 motherboard (the one I got fixed after it broke) along with a bunch of other parts and desided to put another rig together. I took the Athlon XP 1900+ out of my water cooled rig and desided to use it in this one. Now for some reason Im having fun problems with the processor in this rig. First when I went to boot it up it detected it at 1050mhz, which was ok because the fsb was set to 100 and not 133. So I set it to 133 and then the motherboard picks up the 1900+ proc as a 1600+. I then noticed that gigabyte had changed a jumper which set the multipler to the one a 1600+ would use. So I set it back to auto and then go to boot. I hear the HD start up, then stop, start up again, stop, then start up again and stay on but no picture appears on the screen!. Then I went and set the jumper to 1900+ settings and the same thing occured. Then I went and set the jumpers to settings for a 1800+. The pc posted and I figured "hey only a little slower.. no big deal.. ill stick with this". So I begin to install windows and right at the beggining where the screen is blue and windows setup is loading stuff, the installer stops and the pc locks up! I restarted only to find the same thing happen. Then I went and turned the pc off for a few and then turned it back on. This time I got a little farther in the setup before it locked again! My temps from my CompuNurse temp probe said they were around 51 when it locked. Now this keeps happening and I dont know why.. does anyone have a clue?
