Also a recommended replacement from there of a Geforce 440.
The gts 240 is an OEM card used by Dell and maybe some others. I looked on Dell's site for driver support for that card and could only find drivers for up to windows 7. Nvidia does have a Geforce windows 10 driver--version 341.74--that would work. I can't give a direct link but start here:
The automatic update or auto-detect gpu would probably work but if you do the manual search the options on the right would be:
Geforce 200 series
Geforce GTS 240
Window 10 64 bit (it's the same download for 32 bit)
Edit Oh well, here a direct download link:
So either a good cleaning, card replacement or driver update should get it going.
