Game won't start
Hello, I have been playing The Sims for six years on this same laptop. I haven't had any issues besides old/broken mods so far and I have been able to fix them myself very easily. The laptop is Acer Nitro Geforce something, and it was one of the best of the year when I bought it. Runs smooth and great with full graphics, so I don't think that's the problem (or who knows?). It's still in great condition, except that it is a bit noisy, lol.
So the game won't start. It started acting funny this week, i.e. a few days ago. Loading times went through the roof, the game started to work slowly, lagging, etc. Then it started crashing on random intervals. I deleted the mods I had downloaded recently and eventually quite a lod of mods. Tried old save files. Read the crash reports which were mostly incomprehensible. Cleaned caches, repaired the installation, etc. etc. Finally I thought the game worked and played a resurrected save file for two hours, no problems except huge loading times. Then the game totally freezed suddenly, and I couldn't do anything. I had to close the program with ctrl+alt+delete. After that the game hasn't even begun loading. Not in the EA app or by clicking the TS4.exe file. It tries to start, the screen blinks etc. but then it goes back to the EA app. Also, my desktop is acting weird. I can draw random black squares on it by clicking my mouse. I don't know if this is related to the game or if I've just missed this feature over the last few months?
I use Avast, I already checked that the game files are among the exceptions, also from Windows Defender. I checked that all the .exe files are correctly connected from all folders and the desktop and EA app, since I know there are several options. Of course I could've missed something. I have checked that I have the latest Intel, Nvidia drivers, everything. I made a game refresh and started the game from scratch by making a backup of my old Sims folder and downloading the game and add-ons all over again. IT STILL WON'T LOAD. I don't know what to do anymore. Now it at least sometimes pops up a notice saying that "could not start, alustusvirhe during launch" (sorry I don't know a proper translation for that Finnish term, I play the game in Finnish). Format error or something? Do I really need to try to fix my hard drive or what?
Please help :(
