Hi all... I have a new machine for centos 5. amd 6000+, 2 gig and 750GIG drives. Price is quite reasonable... Anyway... centos 5 installs fine, I was running fine then the machine just turned off. I tried to run a video for the last 8 hours on it waiting to happen again and it worked just fine. I then did a continues compile with a batch file and after a few minutes it just turned off... I saw the length of time to do the compiles was increasing. At the end about 10 seconds extra than the time when I first started.... I immediately jumped into the hardware monitor for CPU temp and it is registering 45C. around 114 F. Seems OK at this point.. I have heard before RAM or power supply. Do these symptoms still point to that? Does the power supply seem more likely than RAM? The RAM is DD2 Corsair. I am doubtful that the kernel just died or something for froze as the machine TURNS OFF. THanks for any tips. Jerry
