Brand new Cyberpower GUA3700T Constantly Freezing up

Like the title says, I recently purchased a new Cyberpower GUA3700T pre-built PC from TigerDirect. The computer arrived and I set it all up after I made sure to the best of my knowledge that the parts were all seated correctly. The computer ran great for the first week or so, although I was really only downloading steam games the first week.

Week 2 now whenever I am playing more intensive games (FarCry4, Fallout 4, Call of Duty Advanced Warfare) after about 2-4 hours the computer would freeze up and become totally unresponsive and make a loud repeating buzz noise through my headphones. I would hit the reset button and it would be fine again for another 2-4 hours but again the same crashing issue.

Last night I encountered some different issues now, while I was alt tabbed out of FarCry on chrome and approaching the 2 hour mark the computer froze up again! I had been attempting to figure out what was going on and I had speccy running in the background which was visible during the crash, temperatures were all fine (i wrote them down but currently am at work and can't view them), the GPU was running at 80C which was the only really hot part. I live in Sudbury, ON, so the climate here is currently pretty cold and I was running a ceiling fan drawing air in to the room as well. A second crash occurred over night after I had left it running to do a windows update and when I woke up to inspect the machine and make sure the updates were successful and turn the machine off it was unresponsive, the monitor wouldn't even turn on from moving the mouse or ctrl+alt+del.

I have run Prime95, Novabench, 3dMark DX11 free edition, and the default windows Memory Diagnostic Tool. All turning up good results.

I don't really know where to go from here to troubleshoot, I suspect it might be a PSU issue how ever as it seems to be a generic brand and I have read a bit about how the standard PSU's these rigs ship with are inadequate.

I have messaged Cyberpower as the machine is brand new and still under the 12 month warranty but any help is much appreciated.

I would be inclined to believe it is the PSU that is the root of your problems - see what CyberPowerPC has to say. Personally, I'd be inclined to replace the PSU and not bother sending the unit back to CyberPowerPC - this thread may help you decide on a different PSU http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html of course they may tell you that if you replace anything it'll void their warranty - it's something to find out from them.

If I were to use MSI Afterburner and lower the total power draw by "underclocking" the CPU, would you expect that to "solve" the problem temporarily? If this makes sense I could use this to test and see if the crashing continues or is this just a really bad temporary bandage that might do more harm than good?
 
It is something to try although I can't say how effective that may be (or whether it would be a good thing to try). The problem with funky PSU's is that there are a number of things that the PSU can be doing which could cause problems (cross-loading poorly, poor voltage regulation etc.) those things would not be effected at all by lowering clocks - it may not simply be a matter of the PSU's inability to supply enough current (underclocking would help that) to the system.

If I was to go ahead and change out the PSU on my own, what are some general rules to follow? After a quick google on the subject I found that I have to match the form factor of my PC, which happens to be labelled as ATX. Using that list you provided, I found one that is not too expensive and still in Tier 1 but it is an ATX12V. What is the difference between ATX and ATX12V PSU's?

This is the PSU I was looking at for reference.

Those are excellent supplies, I have the same unit and it should definitely be a much better fit than the 800W generic.

I took a look at the actual PSU inside the computer today and the model number is HPL-800BR-F14S. A couple other people posting to forums like this one have also noted that it's a lower end unit so I think this is definitely the issue :(
I called Cyberpower support directly and was told to try re-installing my games and trying them again... so no help there.
I might end up going for that EVGA G2 Gold if it is as reliable as you say.

I finally installed the new EVGA Supernova G2 850W PSU that I found through that tiered list of PSU's you had linked and it worked! I almost couldn't believe it! Running Call of Duty for 1:30:00 and no crashes or freezing issues encountered. Will run more tests on different games but so far everything is coming up Milhouse.
