| 1219357 | 2011-07-28 08:59:00 | I have been on the machine tonight and it has shut down twice in the last tem minutes. I have decided I don't think this a problem with the monitor now as when it goes blank the keyboard lights remain lit but if i press caps or number lock nothing happens which to me (i think) suggests that something is happening "in the case". I have got easy tune running and all the temps seem normal to me, was wondering whether it was a temp thing as it has happened both times when i've been watching a couple of videos on line ? Is there any way I can set up a logger that'll record temps etc so I can analyse after the event. Just as I was typing this the alarm came on for easy tune and when I flicked over the FAN CPU which is set at 1500RMP had dropped to below this level. There is also a little red light against this also - so I am now guessing perhaps this fan is not working properly and the CPU is overheating ? Anyway of checking this without dismantling the whole thing ? |

| 1219359 | 2011-07-28 09:09:00 | the strange thing is when this warning alarm goes off the CPU temp is only around the high 20's which I wouldn't have thought would be an issue at all ? Its almost as though the fan is only running intermittently |

| 1219360 | 2011-07-28 09:15:00 | Probably the CPU fan warning is triggering because the CPU is quite cool (20-something degrees) already thus the fan is running slower than usual since it doesn't need to do much to keep the CPU cool. Doesn't explain the freezing though... unless it's literally freezing... :horrified |

Many people get black screens or freezing when the psu can't supply for the gpu. :pf1mobmini: ?? Huh ? I've got a decent PSU (620W) running a Sapphire HD6850 1G GDDR5 which I was led to understand should do the job ? |

| 1219363 | 2011-07-28 12:31:00 | If part or all of the psu is dying it may not be producing the full 620w or even if on of the Pcie power cables is shorting. Idk that was just a guess. :pf1mobmini: |

Idk that was just a guess. :pf1mobmini: So I guess from my perspective how does one start to test these things ? Obviously I don't have a spare PSU so is there any software that'll allow you to test things without doing the replacement test ? |

| 1219365 | 2011-07-28 20:55:00 | If a power cable was shorting out it would trip the PSU protection and the PC would power off completely, not lockup. No software exists to test a PSU. All testing would have to be done with hardware (load tester, oscilloscope etc) However if your PSU is a recent model of a decent brand it's probably OK. What is the PSU and how old? But I would start by running things like Memtest, and checking the system logs for anything strange related to hardware or software. |
