Sabertooth X58 random shutdowns
Just recently my computer started to shutdown randomly. Sometimes after
several hours and sometimes after a couple of minutes. After several weeks of this I didn't use it for a week or two. After turning on again, the monitor said no video. Today I replaced the video card and same message. Replaced the monitor and got video back. Booted up and everything came up for about 5-10 min. and then shut down again. The unit is 16 months old, with an Intel i7 -960 and 3 sticks of 2G dominator memory. I don't know what to do next.. Appreciate any help to resolve this issue. Guy |

Perhaps it is time to do a little housekeeping, such as cleaning out the fans and fan filters, the dust and lint that might have gathered inside the case, renew the thermal compound between the heatsink and the CPU. At the same time, refresh the contacts of the peripheral cards and memory. Remember, the i7-960 is a "hot" CPU, even when not driven too hard. GR |

Appreciate any help to resolve this issue. Guy Are you monitoring the CPU temperature ? Both Intel and AMD processors have internal thermal protection. The signal that comes out of the processor is THERMTRIP. If the CPU thinks it is too hot, then the CPU asserts THERMTRIP and the ATX power supply should shut off. THERMTRIP is a logic term to the PS_ON# signal the ATX supply uses. PS_ON# is an open-collector signal. You can ground PS_ON#, by joining it to an adjacent COM (common or ground) signal, and keep the ATX supply running. However, that would also prevent THERMTRIP from protecting the CPU from overheat. It would keep the computer running, but put your CPU at risk if it really was overheating. It could also be, that something is sending a "regular shutdown" to the PS_ON#, and causing the fans to go off and the main section of the ATX supply to stop. That would be harder to figure out. As to why some software path might do that. But THERMTRIP is an example of a hardware-only path. Nothing gates it, and if the CPU thinks (even, erroneously) that the CPU is too hot, then the power is going to go off. 1) Monitor CPU temperature. 2) If CPU seems too hot, remove heatsink/fan assembly, re-apply fresh thermal paste, install heatsink/fan assembly again, and retest the CPU temperature. Before starting that process, make sure you have a tube of thermal paste handy. 3) When you think it's fixed, test with Prime95 torture test or that Intel burn-in program. Those are programs that attempt to run the CPU at 100%. The cooling system on a computer, should be adequate to keep the CPU below critical temperature, even when it does a length calculation. Sitting idle in the desktop and not seeing it power off, is not a sufficient test. Use a good "loading" program, to test that it is really fixed. A loading program can also be used as a form of proof that it is THERMTRIP that is doing it. In that, it might shut down soon after starting the test program. A range of Intel processors, Intel used low temperature solder, to solder the top of the silicon die, to the metal lid on the processor. For the latest processors, Intel has stopped doing that, and is back to using thermally conductive filler between the top of the silicon die and the metal processor lid. I think the previous soldering scheme was a more reliable mechanism, in that there was less opportunity for the solder to "leave the area". A recent picture of a Haswell processor opened up, shows a grey material now present as a conductor of heat. If for any reason, the thermal path inside the CPU is interrupted, that can be enough to cause the CPU to overheat. If any of the Intel warranty remains on such a processor, you'd attempt an RMA to get it replaced. The warranty terms on a boxed retail processor with fan, may be different than a tray-container OEM one. (I'd have to go and look that up, since processor replacement doesn't happen all the often.) The warranty might be three years, but you should go look that up. It could also be something like the ATX supply overheating internally. Power supplies have a thermistor attached to an internal heatsink. If the supply thinks it has become too hot, it may shut off. But in that case, it may require toggling the switch on the back, to get the supply to restart. So there are subtle hints like that, as to whether the switch-off attempt is coming from the CPU/motherboard, or from the ATX supply. Paul |

GR Ghostrider, I keep the computer pretty clean, and that was the first thing I had looked at. There was not any buildup, so I was trying to figure what hardware might be over heating. I had cleaned and reset the CPU / heatsink which is a Corsair H70 liquid cooler with 2 fans. Nothing seems overly hot, and the last temperature monitoring I had done was well within range. Exact temps escape me now! I am thinking it is the CPU or mother board. I had it boot to safe mode with networking and it ran for about 1-2 hours before I shut it down yesterday. Didn't know where to look to pinpoint any specific codes or messages. Just ran it in safe mode again and it shut down in 5 minutes... Thanks for your help, I will probably reset the CPU again and see what happens. Guy |

I don't remember exact temps, but they were always well within range when I was monitoring them. I guess it could be the power supply as it is probably 6 years old, and an Antec II 550. It might be the most cost effective item to start replacing! It has been used thru 3-4 separate builds over those years. I assumed if it was the PS it would just quit altogether. It is strange that it would work for 2-5 hours and sometimes shut down in a few minutes after windows started. |

But even if you were, a 550-Watt PSU is inadequate for this ASUS motherboard and CPU. As a custom builder, I usually use a minimum of a 750-Watt PSU for an X58 motherboard with the Intel I7-950+ family of CPU's. Paul might have the right idea of issues with the [old] PSU. GR |
