Computer reboots - Please help!!

[Final8Demise]

Ok...I'm at my wits end, I'm throwing in the towel. I've upgraded my PC and now Path Of Exile will cause the PC to reboot randomly generally within 1 to 5 minutes (no events, no BSOD even with the "Automatically restart" option unchecked). I reused my OS SSD and my PSU, everything else is new. I'm getting real close to the RMA deadlines and I really need to figure this out. I've already had to RMA the first motherboard as it was faulty. I've tried everything I can think of, shy of ordering new parts. I havent tried a new PSU because the only one I have that will work is a 850+B but I don't think that is the problem. I can run Skyrim, Fallout 4, and even Space Engineers at max for several hours and every other game I have on max and it runs fine. Its passed Prime95, Furmark, and Memtest86 (after a 3 hour goose-chase thinking it was the RAM when in fact it was the faulty CPU mode in memtest86+) and temps are all good (CPU < 60 and GPU < 70). So far, everything I've thrown at it works with flying colors, except for POE. It generally crashes when I get into a instance and start fighting. Ever since the new GPU I've been getting the D3D fault error when adjusting graphics settings and something about shader out of memory exception. I've also tried a fresh install of Windows 10, different GPU drivers, and disabled all the sound devices. I reinstalled my GT760 and it ran fine for an hour.

So if anyone else can help me pinpoint the issue, I would greatly appreciate it.

Current: It finally happened on Skyrim about 1 hour in. Could it possibly be the PSU? I'm running Prime95, IntelBurnTest, and FurMark as I am typing this and it is still running fine. Temps stable at CPU (67) and GPU (78C)?

I would replace that PSU, no matter what. Raidmax power supplies are not quality units. Stick with tier 1 and 2 units, only. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

I agree, the power supply is absolutely the culprit. You've got a killer rig that's being crippled by using a very low tier power supply that's incapable of handling the voltage outputs required by the motherboard and graphics card. Buy a new PSU from a tier 1 manufacturer (EVGA G2 / B2 / P2, Corsair AXi / HXi, Seasonic X / G, FSP) and it should solve all of your problems.

That's an Andyson built unit, and supposedly, according to JG, it's a decent unit, surprisingly. That still doesn't mean it isn't the problem though.

I avoid Raidmax like the plague, and for the price of that unit, you could have bought any of several of the best units on the market in terms of clearly superior internals and platform. Still, I'd manually test it and also post some HWinfo (NOT HWmonitor or another utility) sensors only screenshots of the system voltages while under a Furmark or Prime95 load and post them here.

Thanks for the suggestions. I bought this several years ago when "big watts" were coming of age and it was relatively inexpensive for the time. It works great for what it is and still does, however, the 4 rail setup I think is just a faulty plan.

So Skyrim finally caused the system to reboot after an hour or so. So then I really start to question the PSU. So I start up Prime95(max), IntelBurnIn(max), and Furmark(max) all at the same time. Sytem running with ~30MB of RAM and my temps are CPU(67C) and GPU(78C). Ran several of these tests for a little over an hour...nothing, ran fine. Start up POE (which I have framerate capped at 75FPS), go into an instance and boom, it reboots. WTF!! So I finally tear into the other machine and pull out the EVGA 850 B2 (1 12v 70amps). I've played around a little clearing out several maps but this PSU seems to have helped. I wish I would have followed my instincts earlier and just tested it out, would have saved me a lot of time and headache. But I just can't fathom how these programs that tax the system way beyond anything I would run can't get it to reboot but something light like POE can do it within 2 minutes! Please, if anyone can shed some light as to why or how this can happen I would love to figure it out.

So bottom line, if it continues to run fine over the next few days, I will order another PSU! Probably getting the EVGA 1000 T2.

Yeah the one thing about power supplies is that they are not one component that you should carry over to a new rig. They do have a shelf life. Even the best power supplies on the market really should be replaced after a period of about 4, maybe 5 years at the most. And another thing that most people usually don't know about power supplies is that the concept of "big watts" worked very well about 5 - 6 years ago, but right now CPUs and GPUs are getting more energy efficient with each generation and because of that the power supplies have to be accommodating. What works with one generation of PCs definitely is not going to work with the next.

You mention having tried "different" GPU drivers. Have you tried doing a CLEAN install of the graphics drivers? Sometimes installing and uninstalling different driver versions just makes the problem worse, even just upgrading from one driver version to another can bring a whole slew of problems with it that doing a clean install of them won't do. I'd try that first, since it doesn't fail in Furmark or Prime95, which definitely load up the PSU more than any normal use would do, and lead me to believe that perhaps there is a registry setting or other driver related issue that is causing the problem.

The graphics driver I did with the reinstall of Win10. Went back 2 versions. HWMonitor temps and voltages were all right where the should be, didn't fluxuate but maybe a tenth of low and Max. Like you said, I'm baffled as to how this could happen but I will just chaulk it up with everything else I've learned about PC's...they just like to F with ya! I played Skyrim for about 2 hours and an hour of POE with no issues.

I'd be very surprised if it was not the PSU as mentioned earlier by various members, but it's also possible there's something going on with the card itself. Like Logain indicated, I'd replace that PSU just as a matter of course, whether it's the problem or not, which it likely is.
