Hello!
I've been having some issues with my PC lately and I'm at my wits end. The main problem is that my PC seems to randomly shut down when under load and I can't quite explain to myself why that happens.
As an introduction, during the course of this last year I've changed three PSUs and two different sets of RAM- so either I'm incredibly unlucky, or something really wrong is going on.
My current specs are:
Gigabyte H87-HD3 Mobo
Intel i5-4670 3.4ghz
Nvidia GTX 970
8 GB Ram
Cooler Master G700 PSU
Windows 7 64 bit
I started noticing this problem a monthish ago when my PC would shut down by itself. That only happened once, so didn't think that was serious. After a few days I upgraded my GPU and got a 970, and the problem represented itself- the PC would shut down under load (mostly while playing games), stay off for less than a minute, then turn itself on again.
After a while of this I thought there was something wrong with the PSU, as in it couldn't handle the new GPU (I had a CM 550W, which should have been enough). Eventually, after shutting down a few times, the PSU decided it had enough and stopped working entirely- I tested this on another computer and it wouldn't start.
So at this point I pretty much narrowed it down to the PSU not being able to handle the new GPU, so I replaced it with a 700W thinking that would do the trick. Well, it didn't- same exact problem as before.
At that point I ran some other tests and it turned out that my CPU was overheating a little bit. I ran the standard OCCT test and the temp shot up to over 85° in just a minute, so thinking that might have been the problem I cleaned off the old thermal paste, applied some new one, and installed a Cooler Master 212 Evo cooling system. I ran the OCCT Linpack test and the CPU temp never went over 70°. So then again I thought I had fixed the problem, but it's still here.
It's worth noting that with every single test I made, everything seems to be in the norm. The power consumption is ok, the GPU temp is ok and so is the CPU temp. I kept scanning stuff with HWMonitor, GPU-Z while playing games, I ran a memtest that gave back no errors, and I ran the AIDA64 stress test which again gave absolutely no indication that something is wrong.
Still though, the random shutdowns happen. Sometimes they don't occur at all, sometimes they occur after having played for one hour, sometimes after 15 minutes, and so on. I can't seem to pinpoint once specific action that causes the shutdowns- they do, however, only happen when I'm playing games. I thought at first the more demanding games were causing it, but I recently discovered that even older and less demanding games are causing shutdowns now.
The one thing left that I haven't tested yet is the possibility of power surges. As I mentioned earlier I already had to replace several components during this past year- and in December 2013, exactly one year ago, I built this rig from scratch after that the mobo on my old one died (how? no idea).
I'm still quite skeptical about this option though since I can't quite explain why surges would only hit when I'm playing games. No other appliances in the house seem to suffer from this, and the computer never shuts down if it's not under load (I could use it for hours for work or browsing and nothing ever happens).
How should I move from here? Any help would be greatly appreciated! I'm afraid that those abrupt shutdowns will end up damaging some of the components in the long run.
