When running GTA 2, the free download, it runs fine on my XP Home at the normal speed. After between 5 and up to 60 minutes later the game just shuts down - I end up back on my windows desktop without a trace of the game ever running. Can anyone help, I'm hooked but fed up of the same first few missions!
it may be a drivers problem, or your windows is getting bad.
try to reinstall your system, and update your video card drivers (sometimes the newest drivers can fail, only use wich ones works well)
if the game makes your pc reboot, may be an exe infection, usually Win32/Parite.B
