Hi, I just setup the AMD 64 with the K8T board, Thermaltake fan and Arctic grease. While trying to set up the funky bios I had to do a few restarts and after about 10-15 minutes of this I got a lockup. I cleared the cmos and checked all the connections, reseating some. After rebooting the video wouldn't initialize and the LED diagnostic indicated CPU failure. Would the cpu fail after a few minutes or does it look more like the MB? I'm sure the fan/thermal grease was installed correctly. Grateful for any ideas since I don't have another cpu to try and couldn't afford one now anyway. Thanks UJones
