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

I looked at the startup of the machine and cpuspeed dies with a seg fault. Jerry

It could be RAM, CPU, mobo, power supply, etc. *shrug*. You could run memtest86+ for awhile to test ram. lm_sensors can check temp and voltage levels. Otherwise you pretty much just need to figure out the good trigger, and swap hardware until you find the culprit. -- Garrick Staples, GNU/Linux HPCC SysAdmin University of Southern California -------------- next part -------------- A non-text attachment was scrubbed...

Did you set memory voltage in BIOS memory voltage to what is spec'd by Corsair for the DDR2 modules you have? Most BIOSs set the mem voltage via the SPD setting of the memory module unless you manually change it. I would run memtest86 overnight and see if it finds anything. 2. BIOS issue[s] -- you didn't say what motherboard you have (or even whether you put the system together yourself or bought it pre-built). Sometimes BIOS upgrades are needed to properly support newer hardware. 3. Power supply. You didn't mention what video card you have (if any) or the brand and wattage of your PSU. Is the ouput of your PSU aqequate for the power requirements of your hardware? Inadequate or cheap power supplies (even Antec TruPower) are notorious for causing problems like you are experiencing. Assuming your PSU is sized properly, the best way to diagnose this would be to measure the output of the rails and see if they are fluctuating. I sympathize with you -- gotta be frustrating when your shiny new hardware, powerful though it may be, doesn't stay up for 12 hours.

I had a problem with my computer here @ work shutting of randomly. It was a bad power supply fan. Eventually, the computer would shut off after being on only a few minutes. One day after repeatedly turning it on again, I got the smell of burning electronics... The rest of the computer was fine, but the power supply was toast. If the power supply over heats, I imagine that could affect the output, which may slow down your CPU... -- Prentice The contents of this communication, including any attachments, may be confidential, privileged or otherwise protected from disclosure.
