Black Screen/Buzzing Crash(Update, NOT fixed)
I am at my wit's end and have no clue what else to do. This will be long so I can explain. I am praying someone here can help.
Probably around December, everything with my game was fine. I had probably 100 items of CC (hairs and clothes mostly) and used Nraas story progression mod (my first time ever using a mod). The reason I only had 100 was because every time I'd try to put more in, my game wouldn't load. It would get stuck like halfway through the bar while loading my family.
So, I downloaded the new baby swing (so this started whenever that came out) and put it in with my other custom content. My game loaded but after like 30 seconds or a minute of playing my house, my screen would just go black and I'd have this buzzing/skipping sound coming from my speakers. I had to hard restart my computer. Took the swing out, kept doing the same thing. Took the mod out, still was doing it. Tried to make a new town, same thing. I quit playing.
Fast forward to today, I get Showtime in the mail. I remove CC and install. Put my CC back in, including baby swing and mod, it does the same thing. Again, I remove one at a time and then both, still does it.
I decide I'll uninstall all EPs and base game and reinstall. I do that, uninstalling my saved games, etc. that it asks you when you uninstall the base game. I reinstall base/all EPs. Put in NO custom content. I go into CAS and 2 minutes into it, I get the black screen and buzzing.
I've tried window mode. I've tried turning down the graphics settings. I've tried putting the EXE files on the list for DEP. Nothing.
I uninstall everything AGAIN and only install the base game. It starts fine. I go into CAS and just use whatever Sim they gave me. Moved him into a house. I go to buy him a bed and IT HAPPENS AGAIN. Black screen and buzzing. WHY IS THIS STILL HAPPENING AFTER UNINSTALLING EVERYTHING?!?!
I just got this computer (it's a desktop) around June of 2011. I have Windows 7 64 bit, NVidia Geforce GT 430 video card, 4GB RAM, 3GHz processor, 1TB (with around 626 GB free with all Sims games installed) hard drive. I updated my video card drivers. My computer is plenty fine enough to run this game, as evidenced by it working for all that time. I don't play other games so I don't know if this would happen in other games.
ETA: I do get the "your video card is not on the list of known ones so all settings are on high" or whatever dialog when I start just the base game, which according to my research is because its settings are higher than the Sims requires (or something like that). Like I said, though, my computer played this game fine until I tried to add that swing. Now it's not working even without it.
Someone please help me!!!!!!!!
Tl;dr - I've tried everything and am getting a black screen/buzzing crash even with just the base game. My specs are good enough to play the game. Help.
