Hello , I recently installed an ABIT KT7 otherboard with my XP1800 CPU. It set up like a dream. However, last night my whole system lost life...Nothing, not even a light. I tested the Power Supply and it was cool. I then thought maybe the CPU was bad. So I placed it in my brother's Kt7 MB expecting the MB to act dead. Well, it fired up. But there was no Video. So I said oh well and re- installed my brother's 1GZ. It now it was not working even thought right before I tried My XP1800, it was. Now I'm utterly confused. What do you guys think? or Know.
