Games no longer work

Hi,

I'm having trouble playing games on my computer. I don't have many games as my PC is a relatively new build, and I've never really been in to PC gaming.

I recently installed Bully: Scolarship Edition, and from the start it has caused problems. Every time I played it it would stop working and an error message would come up. I downloaded the official patch for it and it didn't seem to help. Getting bored, I decided to play a different game. I loaded up GTA IV, and as soon as I click on play from The Rockstar Social Club startup, it crashes and says, "GTA IV Fatal Error: Not enough video memory - please reboot your system". I have been playing GTA IV for a couple of weeks now and have never experienced any problems with it untill now, so I know that my graphics card can handle it. I have also tried GTA: San Andeas, and it won't load properly; the main menu is not visible and is just made up of a black sceen with blocks and no writing, and when I try to start playing it crashes and says "GTA_SA.exe has stopped working".

I don't understand what is going wrong here; I'm guessing it has something to do with bully, I heard that it had a memory leak of some sorts. I've done a system restore to before I installed Bully, but it hasn't had any effect.

Can anyone help out?

Thanks in advance.

 

Hi,

Not to worry, I managed to fix the problem - I just needed to change my ATI 3D standard settings to optimal performance and everything seems to be working fine now!

Thanks
