I tried everything

@katelynwstxoxo  Okay, I think it's time for some hardware monitoring to make sure your laptop isn't overheating or similar.  Please download hwinfo (it's free) from here:

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

You don't need to install anything; just choose the Portable version, unzip it, and launch it from Downloads or wherever you like.  If you do want the full installer, be sure to click the button for hwinfo itself, not for lansweeper.

Restart your computer, open hwinfo, choose Sensors Only, and click the button that's a sheet of paper with a + to start logging.  Save the log file to your desktop for easy access.  Wait five minutes, then open Sims 3 and play for at least 20 minutes, in a new save in Sunset Valley.  Don't alt-tab out of the game or run any other programs, aside from the EA App of course, while you're testing.  When you're done, click the same button to stop the logging.

Please upload the log to the third-party filesharing site of your choice (Google Drive, Dropbox, etc.) and link it for me.  Either leave it in .csv format or, if you're going to use OneDrive, create a .zip file, and don't open the log before uploading it, or else my log reader might not be able to interpret it.

I think I did it on the actual program it says my cpu is really high and on red but here is the link I really hope I did it right https://drive.google.com/file/d/1WSyJErG4iwg-THpS5-vE2DA0vbWUrwPY/view?usp=sharing

@katelynwstxoxo  The access to the upload is restricted, so I can't download it.  The file doesn't contain any personal info, but if you don't want it public, you can PM me the link.  Or you can post back when you've changed the permissions, and I'll let you know when I've grabbed the file so you can take it down again.  I'll be online for a couple more hours at least.

oops I private it i think it should work now https://drive.google.com/file/d/1WSyJErG4iwg-THpS5-vE2DA0vbWUrwPY/view?usp=sharing

@katelynwstxoxo  The download worked fine, thanks.  But I don't see any values that should be in red.  What exact categories were showing in red when you looked at hwinfo?  Your CPU was running on the hot side, as was the GPU, but neither was in the danger zone or thermal throttling as far as I could see.

Some kind of throttling would definitely explain your issue, so please let me know what you saw, or if you don't remember, repeat the test.  You can take a screenshot of the hwinfo window (Windows key-shift-S) if you're not sure what you're looking at.

when I had sims 3 running with that program on my game my cpu went to 90 and i saw it was on red like when i stopped the logging but it could of been something else but is that what's making my game lag is there a way to fix it?

@katelynwstxoxo  If your CPU went to 90º C, that's not actually dangerous and also shouldn't cause any significant thermal throttling unless the laptop manufacturer changed some internal settings.  The max operating temperature of that processor is 105º C, and it normally wouldn't throttle until more like 95º.

At any rate, you could try using a cooling pad or fan, or even putting books or similar under the corners and pointing a floor fan at the bottom of the laptop.  The idea is to get more air flowing and therefore dissipate more heat.

it just suck because I use a cooling fan and it still gets hot

@katelynwstxoxo  You could try blowing compressed air into the vents on the laptop.  From your hwinfo log, I don't think there's a serious cooling issue, for example a fan not working or a vent completely blocked.  That would probably cause more severe temperature spikes, whereas what you're seeing now is pretty mild.  But that doesn't mean that there's no dust or other buildup at all.

If you're comfortable doing so, you could instead take the bottom panel off the laptop and blow compressed air over everything.  (That's safer than using a vacuum, which could inadvertently dislodge a small component without your noticing.)  Most laptops do eventually need to be cleaned this way, but I can't tell you without having the computer in front of me whether yours would benefit from that right now.  Still, it's not difficult to do.

I cleaned out the vents and checked the laptop and stuff before it stayed the same, is there anything else that work to fix it its just weird because its a "gaming laptop" but cant run a old game 

@katelynwstxoxo  Like I said, I don't see any signs of overheating in your hwinfo log.  Since you're not totally sure what reading was in the red the last time you played, I think it's best to go back to hwinfo and look for that red reading again, and this time, post a screenshot of what you see so I can check.  There are so many readings in the log, even just for the CPU, and therefore so many possibilities here, that I really need to know exactly what you're seeing.

If it turns out that this isn't the problem, we can start experimenting with other system settings.  But none of that will matter if the computer itself is detecting a problem and throttling its performance in response.
