    Hi two things to try:

    1. remove (or replace) your graphics card.
    2. try booting a Ubuntu USB-thumbdrive, install Qt on that and see if it works.

      I'll give those a shot when I have a bit of time. Hopefully it isn't the GPU - I've got a GTX 970 and I'm not looking to upgrade any time soon.

      Thanks for the help!

        Are you using the nVidia driver or the one from Windows ?

          Newest from Nvidia (which happens to be WHQL, I believe). Installed completely fresh with DDU. Not sure if it matters anyway - I removed my GPU to test and still came up with the issue using integrated graphics alone.

          I was able to get QT installed, as far as I could tell, in Ubuntu Live running from a USB stick, but I was getting errors along the way. You can see a crappy video I took with my phone of it here. Not sure if that's just a quirk in Ubuntu running off of a USB, or if it's a continuation of the issue I'm having with my PC. It seems as if other people are having those same errors on other distros, so I assume it's just a quirk from running it via USB.

          After I pushed through all of those errors, i was able to start QT on the live USB.

            Huh, I looked at your video, lots of pain indeed. But if you can compile and consistently run some Qt examples on the Ubuntu stick, that would mean Windows is a bit loose.

            I'm no hardware guy, but you tested the processor and RAM. And now you've also tested without the GTX970 and still Windows 10 glitches out :-(

            Is it a Skylake processor? Some of these have issues with sleep and Intel's SpeedStep. Try disabling SpeedStep and advanced sleep modes in your BIOS. Also disable sleep in Windows. Just guessing :-)

              Nope, Ivy Bridge - i5-3570k. I think I've disabled speedstep regardless, but I'll take a look. Can't hurt, at least. Thanks for the attempt!

                I have that exact processor (without overclocking though) and I haven't observed anything suspicious about it.

                  Ivy Bridge, then you should have a Turbo Boost setting in your BIOS? Try disable that also.

                    Yeah, same. It's actually worked fine for me for some time. Suddenly, out of the blue and without changing anything, I'm getting errors and crashes all over the place. It's infuriating.

                    Sure do, it's actually what I was using to overclock. I had a slight overclock going for some time with the turbo boost numbers. Tested stable and cool for the longest time. That said, I've already reverted it to stock for test. I'll try dropping turbo boost if there's a setting.

                    Update: Went as far as going with a fixed ratio, turned off speedstep completely, turned off turboboost. No dice.

                      Any chance of having that since the Windows 10th Anniversary update ?

                        I'm with you on that. I'd always suspect software before hardware ... especially the video drivers ... and of course Windows itself ...

                          Unfortunately, at least some of the issues preceded the Windows 10 Anniversary update. The Vive setup was crashing as early as July 28th, when I got it, and EasyAntiCheat was crashing even before that (I posted about it looking for help on the Steam forums as early as June 4).

                          I can't pinpoint when Origin started crashing on me, but I suspect it was relatively recently. I can say that the last game I played on it was about seven months ago, so there's a possibility it has been messed up for a while.

                          I tried rolling back to 362 drivers, from March, for my GPU with no luck. I can try rolling back further, but I can't imagine others with the same GPU/drivers not reporting a similar issue at some point.

                          I'm honestly not super far from demoting this stupid computer to media center and building another one, although I'm fairly certain my head would explode if the problems persisted after a new Mobo/CPU/GPU.

                          That said, I'd be ecstatic if we were able to find a fix.

                            Hmm, perhaps it's time for some slight surgery (not on you but on your PC :):
                            if you have 2 RAM memory sticks, swap them.

                              Was going to try that next, @hskoglund , even though they passed memtest, I figure it can't hurt to swap them, change channels, and remove one and then the other, just in case. I'm going to try that in a bit. Might have to head out for a job really quick for the time being, but I really, really appreciate all of the help you people are offering up.

                                In the same kind of idea, did you try to change the PCI slot in which you put the graphic card ?

                                  Tried RAM, no luck. Tried one of each, then switched slots. No luck. I definitely won't have time to switch the slot my GPU is in, but try that next.

                                    @darkaegis maybe this is a good opportunity for you to switch to and learn Ubuntu (there are plenty of Steam games that work) :-))

                                      Haha, I'm somewhat familiar with Ubuntu - I used it years ago in college and I dabble occasionally, but I've got far too many Windows-exclusive Steam games as well as Lightroom and Photoshop (for my job) that demand a Windows PC.

                                      Plus, many of the issues I've got right now revolve around Vive, which I hear has pretty close to zero Linux support.

                                      If anything, I'll probably dual-boot at some point in the near future, but I don't think I'll do it as a solution to my issue. :D

                                      Something just came to me, by the way - Origin recently overhauled their platform - presumably into qt5. That may have been why I didn't have the issue before but am having the issue now. I can't find a way to install the old version of Origin since they use a web installer and it downloads the newest version by default, but I can say that the graphical glitches and crashes I get in the newest installer aren't present in their older versions.

                                      Obviously I can't say it conclusively, but I can say that the problem seems to be restricted to applications made with Qt, regardless of how resource-heavy they are. Although I'm not sure why some Qt apps work with glitches and some crash outright.

                                        Yeah agree. What about VLC for watching movies (another pretty well known Qt app)?

                                          BTW, perhaps it's some specific Qt behavior that triggers the glitches. Now I'm thinking about the NX settings, have you tried disabling NX in BIOS?

                                          Edit: you can try it from inside Windows 10, open an elevated CMD window:
                                          bcdedit.exe /set {current} nx AlwaysOff
