Re: Playing the Sims causes a BSOD on my computer.

@Eudoxia1  There are ways that involve real-time debugging, but I'm not equipped to do that over the internet, and you wouldn't want to expose your computer like that over a network anyway.  If there is another approach, I don't know about it; the file either gets written or it doesn't.

What I would suggest here is to run a malware scan, just in case, and then do a repair install of Windows.  I'm not saying your computer has a virus, only that when files disappear or aren't being created, malware is a reasonable possibility and should be accounted for.  Download Malwarebytes (the free trial is fine) from here:

https://www.malwarebytes.com/mwb-download

Open it, click Scan > Custom Scan > Configure Scan, check all the boxes both for all scan types and for your C drive, and let it do its job.  This could take anywhere from a few minutes to several hours, depending on the amount of data and whether the scan finds anything., so you may want to set it to run while you're doing something else.  Please attach its report so I can take a look.

Here's how to run a repair install:

This shouldn't delete any of your data, but if you get to step 13 and are NOT asked to keep personal files and apps, back out and start over.

Once you've done this, it's possible that the BSODs will have been addressed.  More likely is that they keep happening, but hopefully in that case you'll be able to find a corresponding minidump or MEMORY.dmp.  If not, I would suggest having someone look at your computer in person, whether it's a tech savvy friend or a nearby repair shop.  For the latter, a shop may offer you a free or low-cost diagnostic service, and you can choose to engage with them further or not depending on what they find.
