@LyradCh You shouldn't disable the Intel graphics as the computer will boot using the Intel GPU to conserve power. You can get the data you need from dxdiag (see above) and you may need to set the graphics driver to use GT 635M for Sims 2 when the game starts. Sims 2 should already be in the Nvidia device driver and setup to use the Nvidia chip. The game should configure itself to default settings if it doesn't properly identify the video chip and the game should run. Sims 2 was a DirectX 9 game. As you didn't post anything about your computer it's really hard to guess what the problem is.
@roberta591 I've tried setting the sims 2 to use my nvidia GPU using the nvidia control panel, but based on the deviceconfig log, it just wont recognise either of my graphics cards, with no device name and the earlier mentioned Chipset: Vendor: 0000, Device: 0000, Board: 00000000, Chipset: 0000. If you want to take a look, i've uploaded the dxdiag and the deviceconfig
@LyradCh First the free space on your system drive is low. While that computer is cute it looks like a laptop in a desktop form (more like a game console) and I don't know the expansion capabilities of that machine (adding storage might be difficult) but like an Xbox One you might add a USB drive to that machine. As you are trying to play Sims 2 a bigger issue is Sims 2 is a DX9 game and Windows 10 is DX12 and DX12 (and DX11) does not play well with older DX9 games. !!!Warning - you will have to change Windows 10 system files for DirectX 9 to work. Here is a link - DX9 on windows 10 I personally play all DX9.0c on an old Windows 7 machine I haven't scrapped yet.
hth
@roberta591 Haha, yeah I've got too many things installed on my computer and been meaning to export them to an external hard drive but been too lazy. I tried installing the Direct x9 on windows 10 from the link but it didn't work either, as the main issue that I'm experiencing is when I do play the game, all of the worlds flash purple constantly as though they were missing textures and when I play a family, all of the walls flash red. Note, i've already tried re-installing the game
@LyradCh What game are you trying to play? Sims 3 plays just fine on my Windows 10 gaming computer - no compatibility mode or anything. I not sure but I don't think DirectX 9.0c and DirectX 12 will run together on the same computer at the same time. If you do get DX9 to install I don't think DX12 will still be active and I like my DX12 games. As DX9 games are less demanding I have an old Windows 7 computer that has DX9 on it. Notice I put a warning in the post. You need to post your computer's dxdiag. Does the flashing happen right away or after you've been playing for a while. First thing that comes to mind is heat is affecting the video memory. If you have a dedicated video card, that memory may be failing. Another issue may be your computer is running out of memory and the flashing may be the texture video memory being swapped in and out of virtual memory. This could be caused by not enough free space on the system drive. Really need the dxdiag to start diagnosing the issue. Most users don't realize their old computer's worth goes down as technology advances. AMD just raised the stakes with Intel with the Ryzen cpu
