Computer restarts when playing Sims 4

@mashmusen  A restart is pretty serious and a sign of a hardware issue.  Please undo any overclocking settings you currently have, and test again.  Please also let me know what you have for a power supply: manufacturer, wattage, and rating, i.e. Corsair 750W 80+ Gold.

Your dxdiag lists a number of errors related to the USB 3.0 driver too.  These errors shouldn't cause a restart, although they should definitely be addressed.  It's usually enough to uninstall and reinstall the USB driver, but just to be thorough, please grab a couple of dump files and upload them so I can take a look.  Open a File Explorer window, and copy and paste this in the address bar:

C:\Windows\LiveKernelReports\USBHUB3

For the last two or three files inside, if you have that many, right-click and select Copy, then right-click on your desktop and select Paste.  Zip them together and upload them to a free filehosting site (Google Drive, Dropbox, etc.), and link them here.  Please make sure the upload is set to be readable by other people.

Hey. I can't seem to find any dumpfiles inside the folder in question regarding the USBHUB3 which is weird.

I am using a Corsair CX750m 80+ Bronze PSU at this time. 

I have undone the overclocking a while back and the game crashed the computer way before I tried any tweaking. 

Thank you for your time and I hope we can shed some light into this mystery.

@mashmusen  Dump files can get deleted after some time, or sooner if you have a cleaner app that deletes temp files.  If you do, please disable or uninstall it for now—it's better to be able to find the relevant extra files than to keep your hard drive free of clutter, at least while troubleshooting.

The quickest approach to locating any dump files is to open a File Explorer window and search for *.dmp and *.mdmp (the asterisk, then the file extension). which should turn up any of either kind.  Make sure File Explorer is set to show hidden files and folders; I'm not actually sure that matters when searching, but it's an easy setting to switch back and forth.

If you don't find anything though, it's not necessarily a sign of a problem.  The dxdiag doesn't include dates with its errors, so there's no way of knowing when the USB driver errors happened.  And those errors aren't likely to cause a restart anyway.  Whether you find any dump files or not, it's a good idea to do some hardware monitoring, to see whether there's anything obviously wrong with any of your components.  Download hwinfo from here:

https://www.hwinfo.com/download/

You don't need to install anything if you don't want to; just choose the Portable version, unzip it, and launch it from Downloads or wherever you want.  (If you would like to install, be sure to click the green button, not the orange one.)  Restart your computer, and don't open any other apps.  Launch hwinfo, choose "sensors only," and click the icon that's a sheet of paper with a + sign to start logging.  Save the file to your desktop for easy access later.

Wait five minutes, then launch Sims 4 and play for however long you want, but at least 20 minutes.  If the computer doesn't restart, you can click the same button to end logging.  Even if it does restart, the log should be intact up to that point, but please let me know whether your system restarted or not.  Upload the log to a third-party free filehosting site and link it here.  Please leave it in .csv format, or if you use OneDrive to share, please compress it in .zip format instead.

Hey I used hwinfo as I was playing and not to far into playing the game did indeed crash the computer again. Anyway here is a link to my googledrive.

@mashmusen  I took a look at your log, and some of the data was a bit strange.  Did you start hwinfo before or after you launched the game, and if before, how long did you wait?  How long into this process did your computer restart?  I don't need an exact timeline, but a rough estimate would be great.

I ask because the log has six minutes of readable data followed by a very long list of completely blank entries.  I'm curious whether your computer was running and hwinfo was just not recording data during that time, or whether the restart happened at the point where the readable info cut off, and the extra is just (literally) white noise.

One other detail of note is that your GPU was already running at 58℃ when the hwinfo log started, despite the other internal temperatures being much lower.  This would be totally unremarkable if you were already playing when you launched hwinfo, but potentially an issue if you were not running anything GPU-intensive at the time.  The card's fan also repeatedly started and stopped, which again isn't necessarily an issue under minimal load, but might be an indication of a real problem.

Please let me know about the log, and if you want to do a bit of poking around, please remove all the connectors from the PSU to the other components, make sure there's no dust inside them, and reconnect them.  Take a look at the GPU fan too, just to see if there's anything obvious: does the fan seem to catch when running, does it have excessive dust, etc.  Please also let me know the exact model of graphics card you have, not just that it's a 2070 Super but its manufacturer (if it's a partner card) and model name.

While you're inside the case, look for bulging capacitors on the motherboard.  A new one like yours shouldn't have any issues, but it does occasionally happen.

Hey again. I let the hwinfo run for 5 min without anything else running before starting The Sims 4. I made sure it ran properly. I dont know exactly how long it ran bit my guess is around 15 minutes. I have reinstalled every cord inside the computer at some point. The gpu manufactorer is gigabyte. But I saw something now that i looked at my gpu. There are two outlets for plugging in cords. One six pin and one 8 pin. I had only used one cable for all outlets although I had two cords at home. You think this could be the source of problem? 

The temperature is quite high indeed. Although this GPU dont use the fans in idle mode. In HW monitor it showed that one fan spun when it did not. I changed the speeds on my case fans and rearranged them a bit and the temp has stay at around 37 - 39 C 98-102 F. 

After playing a while again even though putting the extra cable the computer crashed...

I'll check soon more about the graphics card. Running a diagnostic on the ram right now.

A link to more specifics on the card

Couldnt find any bulges either on the motherboard

@mashmusen  Do you mean that you only used either the 8-pin or the 6-pin connector for the GPU, but not both?  You absolutely need to use both connectors on a graphics card like yours; I'm surprised the card would work otherwise.  Please make sure that both connectors are plugged in securely, and that you're using connectors that both say PCI Express on them, and that they're connected to the PCIe outlet on your power supply: some connectors can look equivalent, but they don't function the same.

The idle temperature on the GPU should also be much lower, although the temperature under load didn't get particularly high in the minute or two you were running the game.  Since hwinfo is picking up only one fan, please make sure all three fans on your card are spinning properly.  (It could be that there's only one sensor covering all three fans, but it's better to double-check.)

If the RAM tests don't pick anything up—please let me know what you find, and with which test(s), and whether you tested the modules separately—run hwinfo again while you play, and get another log.  It's possible the first one was simply corrupted in some way.  In case that's not what's happening though, please run Sims 4 in windowed fullscreen or windowed mode, and tab to hwinfo every couple minutes.  Check CPU and GPU temps, and let me know how they look, or you can screenshot the hwinfo window in a couple places and go back to look later.
