My machine seems to die whenever the CPU does any large amount of work. This is like running a few programs and transferring files. I didn't have any issues with XP.

I didn't install any Mobo drivers, could that be a problem??
Any thoughts would help!

Hardware :

  • CPU : AMD 3700+ ATHLON 64 939P RT 2.20 gigahertz
  • Mobo : MSI K8NGM2-FID GF6150 939
  • RAM : 2 x 512mb of DDR 400 ram
  • Video Card : MSI N9500GT-MD512M
  • HD : Maxtor 200gb SATA + WD Green 2TB SATA

Updated : When the machine does shut off, the power light does a slow blink. To turn it back on, I have turn the power supply off for a bit and/or pull the power cord out until the light turns off.

Might not get a meaningful answer with that title. –  user4124 Jan 27 '11 at 18:02

die meaning what? it shuts down? it overheats? it coughs, spits and collapses? what does it do? –  RolandiXor Jan 27 '11 at 18:38

It sounds like its overheating. Are your fans working? –  dv3500ea Jan 27 '11 at 18:56

have you tried to clean up your fans? dust can kill any machine regardless of the OS, also it can be failing hardware... –  Uri Herrera Jan 27 '11 at 20:08

Install lm-sensors to see the temperatures. See issue 43 of Full Circle Magazine, the Q&A section.

I have a temperature readout on my case, it's not reporting anything crazy. But I'll install the Im-sensors tonight. –  DjFarout Jan 27 '11 at 22:05
    
So, tracking the temp and tweeking it helped. Also the system is in a MicroATX case and the mobo was off it's tracks. I'm not sure which fixed it, but its working now! –  DjFarout Feb 1 '11 at 16:40

If you need to throttle the CPU usage of a game for example, you can use cpulimit. See Can I limit the CPU usage of a single application? I had to do this with a game called Tibia which is a CPU hog on Ubuntu, its now limited to 50% CPU with cpulimit.

Additionally - you can try installing CPULIMIT and control the beast's cpu consumption. I had this problem with my DELL N5010 & I couldn't do anything with the fan speed. Installed CPULIMIT and throttled the Video conversion utility. I am able to get things done without my Laptop crashing - though, the speed is compromised. Well - I guess it is about to be the case - and better than looking for a fan replacement (or whatever else).
