AMD box keep crashing

I have a weather proofed box with powerful fan at the roof top which may have 25 to 32 degree celcius heat inside the box. and lots of humidity.

motherboard is Asus A7V8X-MX SE and using sempron 2000 (1.5ghz) which was working (max) 15% cpu at 20MB and 10 mb only 5 percent at peak.

but this box is keep crashing, and it is very hard to for me to reboot it because of my limited access to the box.

so there is couple of question in here.

  1. how to reboot my box when cpu is crashed? while I can’t connect ssh/telnet/winbox from either ethernet or wireless card, and it doesn’t even send any wireless signal (DEAD MEAT)

  2. possible to reboot remotely with lan wake up thing? I never tried that but in case… only when cpu is halted

  3. possible to reboot from SERIAL port with handphone connected? and again cpu halted

  4. whats the better option to upgrade? I was thinking about either of these cpu:
    CELERON 2.0A GHZ / 128 CACHE / PIB
    CELERON-D 2.4A GHZ / 256 CACHE / PIB

and either of these mainboard:

ASUS P4GE-MX / INTEL 845 / 533 FSB/ 1MB CACHE / V+S
MSI P4MAM-L / 6787 / V+S+L

just to add I am using two wireless card making nstreme2, one is 5212 (senao) and other is 5213 (gigabyte) atheros chipset from

  1. Is there any device to absorb humidity and cool down inside my metal enclusure? something like those small refrigator made for computer casing.


    Thanks in advance

You could look at water cooling, a WaterBlock on the CPU that gets pumped around a small rad outside.

  1. Sometimes there’s a BIOS option to determine what the system does after a power fail. If you can set that to turn the system ON, then you can power cycle the box to get it to reboot. Alternatively, there are some PCI cards available that give hardware level remote control.

  2. You could try WOL but it’s designed to just wake a box from sleep, not reboot.

  3. You’d need a separate piece of hardware, connected to the phone to do the reboot. The serial port will be dead.

  4. Doubt you’d notice the difference.

  5. I’d seal the box with some dissicant inside. Cooling could be done via some form of heat exchanger to transfer waste heat to the outside. Alternatively, use a low power board and CPU such as a VIA mini ITX or Soekris. These shouldn’t need additional cooling and with no rotating parts there’s less to go wrong.

Hope this helps.
