Hi all, I had asked the other day about my new machine amd 6000+ and strangely SLOWWING down then eventually stopping. I have tried a new 500W power supply, I took out the extra video card, and just used the one on the motherboard (both are nvidia one with DVI one RGB). I took out all the RAM and tried differnent RAM. I ran memtest86 (ran fine until the machine turn off). Harddrives should be fine since they are not active during memtest86. THe temperature on the CPU has never been higher that 118 degrees. This is after it turns off and I go into the hardware monitor. I reset the BIOS settings or loaded defaults. I did download from ASUS the current BIOS for the M2N-MX motherboard. I cannot change the mother board or processor without buying a new one. It is SO STRANGE that the system slows DOWN before shutting off. I run a continuous compile and use the time command to time it. The compile starts at about 16 seconds and SLOWS DOWN to 30 seconds right before turning off. cpuspeed is not running on the box. If anything its supposed to speed up not down. Is there anything else to try or any suggestions. I also boot centos 5 with "noapic" on the kernel line. Jerry
