I have a bit of an issue with my machine that has been happening since I bought it (the entire system is from scan), but it doesn't seem to happen particularly often so i'm not TOO worried about it, but thought it was worth mentioning in case it could cause problems at some point.
Sometimes when I boot my machine up when getting up in the morning/home from work/whatever it will boot up, the fans will start going at full whack as they do and then...Just keep whirring...And then my PC will turn off after about 5-7 seconds or so. It doesn't seem to do this very often though, but when I turn my machine on I'm using it for a good number of hours and I've had absolutely no problems with it other than some faulty memory which Scan kindly replaced. Once it turns off, it'l turn itself back on again, but this time it'l work fine and after a few seconds the fans will calm down and it'l boot. Most of the time it seems to be fine on it's own. When the machine is booted up I've not had any problems.
I spoke to one of my colleagues at work (he has a hardware background) and he suspects that it could be because the CPU is overclocked. Could it be something to do with the voltage when its in POST? and some kind of failsafe to prevent my hardware from being damaged? Is this correct?
If it's quite a normal thing to happen and/or it's not doing any damage to my hardware i'm quite happy as I am, but thought it was worth checking.
The only other problem before getting into the OS that I've had is it saying the overclock failed, and it'l just sit there. This has only happened perhaps 3-4 times since i've had the hardware (about 2 1/2 months?), and hasn't done it recently. I believe some of those times is when I've reseated RAM. I'm hoping it's not really an issue, because I find changing motherboards/processors a pain!
