PC Randomly Turning Off

[boleary]

Anyone ever had your PC turn off in the middle of a song, or when you turn the PC on it begins to boot for a second or two and then it turns off, like someone pulled the plug? I've been having these issue now for four or five months. It happens once or twice and then everything is fine for 3 or 4 weeks and then it happens again. Recently I played for two weeks straight, 24/7, breaking in the NOS1a without a problem. This weekend I had a friend over to hear the "new" system and it happened twice in a row in the middle of a song! I then rebooted in W8, I prefer W7, and all was fine. Rebooted in W7, reinstalled the NOS1 driver, and all has been fine, but I don't trust that reinstalling the driver was a fix.

So is the MB going, the PS or just a bad video card? It not the HD cause it happened after switching HD's loaded with an OS. Another possibility is that there is a short somewhere in the PC. And another possibility is that the automatic shutoff if the CPU gets too hot is randomly kicking in. Though my system is water cooled, I've not had a problem with the pump. And another possibility is that W7 is turning itself off cause I never "registered" the OS on the internet. For years now I've had that, "This is not a genuine copy of windows" verbage in the lower right of the screen, though I input the product key when I first built the PC.

It's going to take a while to trouble shoot this, but am wondering if anyone else has had similar issues?

Brian,

The only sort of hint I may have is that I have experienced similar, but from W8. And what seems to cause it ? the combination of 1.186-i so so speak - the one you may be using only recently (3-4 weeks) - and a too high processor speed. Notice though that "too high" is 2GHz already.

I never sorted it out and just kept on using my 430MHz.

Logically there is a combination of NOS1a and mentioned 1.186-i. So like you, at a certain stage I had to use the both in combination myself.
Maybe this tells something ?

Thanks Peter, turns out I had been using 186i since it came out (and maybe that's when the problem started?) Also, I run my processor at 500MHz (cpu ratio of 12 in the Bios) but maybe that got changed somehow. I'll recheck the bios when I get home tonight.

have you tried disabling xtweaks?

remember there are certain settings with an ex tweaks that could heat up your processor

Thanks Charlie. If it happens again I'll try disabling Xtweaks. Since I reinstalled the NOS driver, the computer has been running 24/7 and I've not had any problems. However, I've had the problem disappear for more than a month before and then its reappeared,  so we'll see what happens.
