Screen goes white, forcing me to ctrl alt dlt in order to close the game.

onyx779​  If you have an HP gaming laptop (Victus or Omen) with an Intel processor, this is a known issue.  There are a few workarounds:

• HELP! The Sims 4 crashes during launch or in the main menu | EA Forums - 12048779
• Game won’t launch | EA Forums - 4992631
• Managed to fix my problem where it crashes during launch after update | EA Forums - 4998584
• Disable the Intel iGPU
• Put the laptop in night mode

None of these works for everyone, but something almost always does, so keep trying the workarounds until you find one that lets you play.

If these don't help, or you have a different computer, please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

Yes, it's an HP Envy Laptop. But it's not on launch. It's during gameplay. I'll try to night mode first. I don't know how to disable the intel iGPU, so I'll do some research

onyx779​  I haven't seen this issue on Envy laptops, and please don't disable the integrated graphics chip if that's the only GPU your laptop has.

Please let me know the context of the white screen, for example does it happen every time you try to load a particular world?

Night mode doesn't work. I'll try the other ones

onyx779​  Again, what I posted does NOT apply to Envy laptops.  And it does NOT apply to cases where the game goes to a white screen during the run of play after loading properly.  So please do NOT try those suggestions.  Instead, let me know when you see the white screens, and post a dxdiag.

It's not when I try to travel, it just happens during regular gameplay. Usually after a few hours of playing

Let me google dxdiag and I'll post

DxDiag

onyx779​  Your dxdiag doesn't list any Sims 4 errors, which may or may not mean anything—it only includes the ten most recent Windows errors.  So the next time this happens, please look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of your most recent white screen.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.
