Newly Built Computer Locks Up During Games

I just built a new computer:

EVGA 650w GQ 80+ GOLD
PNY CS1311 120GB SSD
Seagate 1TB HDD
Gigabyte Micro ATX DDR4 GA-H170M-DS3H
Kingston HyperX FURY Black 8GB(2x4GB) DDR4 2133HMz
Gigabyte Geforce GTX 1070 (Driver Version 375.95)
Intel Core i5 6500 3.20 GHz Quad Core

During games it runs flawlessly up until the point when the entire system locks up. There are no stutters, no screen flashes, or lag. It just locks up and forces me to hard boot. Sometimes it is during the loading screens, sometimes during game play. Sometimes it'll happen half a round in, sometimes 3. I play on Ultra settings @ 144Hz 1080p. I've monitored temperatures. My GPU and CPU run around 60c with my CPU running at 100% usage. I always have more than 2GB of free RAM. My voltages were really low so I RMA'd the PSU and got another one and it had the same readings so I am assuming it's a sensor issue. I've switched my games to the HDD and it still crashes. When I am not running games everything works fine. I have ran stress and performance tests on the GPU and CPU without any issues. I am at a loss here of what the problem could be. Any help would be appreciated. Thank you.

  1. For a hard lock, no warning I'd look at
    (1) disk drive. Do you have another drive so you can swap out the SSD? At a minimum I'd run the long version of the SMART tests from the diagnostic software on the PNY website.
    (2) drivers. Check device manager for any probems. Run windows update again a few times. Reload all the MB chipset drivers using only drivers from the Gigabyte website, nothing from the CD that likely came with the MB.
    (3) unusual USB devices. Unplug anything you don't need.

    Good luck.

    You can download and run stand-alone diagnostics for memory errors. I like "Ultimate Boot CD", but there are others. All can be booted from USB if that is easier. They are DOS or Linux based so will not have any drivers in common with your windows system -- if the PC locks up under load on a boot CD then it's a hardware problem.

    aside: GTX 1070 -- very nice card. New and still in active driver optimization. Try some of the older driver releases just in case some recent update is causing problems.
  2. I have tried switch to my HDD and it still happens. Device Manager is golden. Windows 10 is fully up to date. MB chipset drivers are up-to-date. I don't have anything other than my USB mouse and keyboard plugged in. I haven't done a boot CD and I'll have to try an older driver for my GPU. Thank you for the help tsnor.
  3. I rolled back my driver to the previous build and it still freezes. :(

    REset the BIOS to defaults. SAVE. make sure all overclocking is off. Make sure that memory voltage ends up set correctly based on the memory you have (1.2V or whatever).

    Try removing the video card and see if you can get a hard lock running the integrated video in the i5. If no hard lock on the integrated video (or no lockups when you use a different video card) then RMA the GTX 1070. You can also try UNDERCLOCKING the GTX 1070. Cut it in half for all settings including memory (this is diagnostic, not a permanent solution). If the hard locks go away with an underclocked card and show up when running full speed RMA the card. The problem with underclocking is a bad card can still fail when underclocked, so underclocking does not always tell you what's going on. But if it is stable under clocked, and failing at stock clocks RMA the card.

    Maybe try runnign with one 4GB dimm only. Then swap to the other only. See if the hard locks go away in either config.

    Maybe try reseating all the power connectors. If you have a modular PSU also reseat at the PSU end. Maybe you are losing power from a faulty connection. (I think this is unlikely since you swapped in a new PSU).
  5. There are many things that can cause your problem and some good suggestions have been provided.

    RAM can cause your problem, either weak or defective, or not enough RAM. There are a couple of easy ways to check your RAM for errors. Also, download and install MSI Afterburner - do not use it to overclock your 1070, only use it to check your motherboard [local] RAM in this case. The numbers should be near the bottom of the page. If you are using more than 8GB of RAM at any point a game can lock up.

    I still use Memtest 86+, search for it with Google. Make a bootable CD with Memtest 86+ on it. Put the CD in your disk drive and reboot your computer. Memtest 86+ should start automatically or with very little input on your part.
