I think it problems with new drivers that cause it. Many people report on Nvidia forum that they have problems with new drivers. They have to downgrade to old version around between 296.xx - 34x.xx maybe it would help.
Your Geforce GT 440 have 96 cores. I think maybe not enough cores for most today new games means can't play them due to lag. Geforce GT 440 have 96 cores are near to Geforce 8800 GT / 9800 GT that have 112 cores. That's what old PC games like in around year 2014 or older will able to run fine on it. You have to upgrade video card around between Geforce GTX 650 to GTX 670 will able to play most games and some today new games to date.
My Geforce GT 630 have 196 cores. It do run my legal bought game name are SpellForce 3 and SpellForce 3 Soul Harvest (both are GOG version, not Steam) on most low settings / few medium setting with
NoPostFX-Mode patch for removal of all FX-Effects and shaders in the game patch to improve FPS speed to between 24 - 35 FPS from 14 - 25 FPS without NoPostFX-Mode patch.
My GT 630 would not play most today new games due to video card must upgrade to GTX 1060, 1650, 1660 or above. But if very few new game today with low video card range can play fine. We have to check
system requirement info on Steam, GOG, etc websites that what kind of game we want to play it.
It would cause problems with my motherboard that don't support UEFI. That new motherboards which have UEFI support in around year 2014 and above to now. Old motherboards on year 2013 and older are legacy, not UEFI compatible means new video card like GTX 1650 and above will not work on it to refuse boot up system. There are two different version are Legacy and UEFI which video card need to be support.
I check on Nvidia website for drivers only show up 391.35 to 382.05.
https://www.nvidia.com/Download/Find.aspx
To find more old driver than 382.05 and above, just use search engine like Google, Startpage, etc will show up there.
I never use new Nvidia driver to upgrade to latest version. That's what I bought HP computer from HP website that installed on it from year 2013. Zero problems for my computer since year 2013 without upgrade or update to latest Nvidia driver.
I would refuse to update new driver it maybe can cause unstable driver on my computer. Because I afraid of new drivers that could give more problems on my computer.
I would just prefer to buy new computer. I have to wait until between year 2022 - 2023 when new first DDR5 RAM and Video card with PCI-E 4.0 support on motherboard then I will move on it.
