Re: Constant crashing since June update
@megank48906 A component of the Alienware Command Center is crashing, so please kill it in the Task Manager before trying to play. (You'll need to check the background services list too.) The ACC will likely restart with Windows, or reinstall with the next Dell update, so this is a workaround rather than a fix, but there are ways to block it from running at all if this helps.
If Sims 4 is still crashing, please disable any overclocks: CPU, GPU, even XMP for the RAM. Even if you haven't set any, Dell may have factory-overclocked the PC, so check your documentation. At the very least, you can probably disable the XMP profile in BIOS with one click. I've seen a couple other players confirm that overclocked memory was causing their games to crash.
