Game Crash - PC Restart - No BSOD, No Eventlog, No warning.

Part of the problem with those tests is you're only testing 1 component at a time. It doesn't properly check the load on the system as a whole.

A lot of PC restarts are actually due to low PSU. When you get something happening in game that is not only stressing your CPU, but also your GPU, etc.. you could run into a "low voltage" situation where you are pulling too many watts than your PSU can generate, so it kicks it off and restarts. This is very common in weaker PSUs when you're driving high-end graphics.

So while those tests individually don't cause you any issue, perhaps together they will (if your system will handle it).

Try running every test at the same time... CPU, GPU, Memory, HDD, etc. Force your system to use up all the power it possibly can for a short while. See if it triggers anything.

My psu is fairly new and 750w and surely not all these people are having the same hardware problems?

Not everyone is having the "same" issue.

That's the problem with threads like this one. There are a lot of people getting similar problems but they COULD be related, or they could not be. It's hard to tell. Just because something exhibits the same symptoms, doesn't always mean it's coming from the same place.

That's why we prefer to separate out the threads into people's individual problems, so we can tackle them on their own merits/terms. Not based on something that was perceived as a problem from a different thread.

Most of the "no bsod, no event log, no warning" problems have ended up being a failure in the PSU or the rails, or similar hardware. While that doesn't account necessarily for every case, that has been a lot of them.

a 750w PSU "should" be enough, but there's no guarantee. Also there's no guarantee that the 750w is a quality PSU and that it doesn't necessarily have a manufacturers defect. It happens. That might not be the case for you. It's hard to say for sure since I'm not there to diagnose the PC in person (and swap hardware, etc). I have extra machines around so I can swap hardware whenever I want to diagnose issues. That's usually what I personally do, and I recommend anyone else can do who has the ability. I know that not everyone has spare hardware laying around, and I certainly don't expect you to go out and BUY hardware just to test it.

Just from all my experience, it's very VERY rare to have software cause this sort of problem all on it's own. It's usually caused by poking at a weak spot in a particular way.

The analogy I like to use is: if you had a broken rib already, and I came and poked you... you would feel pain, and depending on the severity, pass out, etc. When it comes down to it, I didn't cause the break. I just caused the pain. The rib was already broken. It's sort of like that. Software can only cause BSODs and other hardware types of problems when there's already a weakness in the hardware or drivers that operate it. "normal" software won't be able to directly cause that sort of problem under normal circumstances.

Hmm, sorry for jumping in - topic is pretty old, so not sure if the problem has been solved. I'm here, since I have similar problem. Still searching for possible cause of it, but maybe it will be of some help that I get PC turn offs (with power instantly off), however all the times (around 10+ I've 'tested') happened to me while idle in A3N on hardcore. If the problem is with some graphic in the game, my best guess would be some weapon/item enchant that a person brings to the town and boom - kinda silly, but that's best I have so far.

If you need any more info or some details I might post them, however I'm not the computer type of a guy, so my knowledge in this is limited sadly, plus I have no solution, still trying to figure out what cause the crash of my comp.

best of luck!

Edit: All the crashes occurred for me while I was on my Ranger with Spectral Throw build. None while I was fighting (thankfully - Nightmare mode) - only in town, so no animation from my side, and I'm not using any weapon enchants.

Instant power-off has to be power related. There is nothing else I know of (aside from motherboard failure or PSU) that would cause an instant power off. If your video card just crashed, it would crash your system, but wouldn't cause the PC to just power off (as far as I know).

The only other thing I can think of that would cause instant power off is some setting on your PC to shut down on BSOD or other critical error. I can't tell you what it is for certain as I don't have your PC, so you'll have to probably do a lot of digging and research... but in the majority of cases, sudden shutoff is power related.
