I am having some problems! please help I have recently assembled a PC based on Intel Desktop Board D915GVWB with Pentium 4 3 GHz, 512 Ram, 80 GB SATA RAID HDD, Samsung Syncmaster 152s LCD monitor, DVD combo etc. I have not installed any graphics card and sound card but using onboard only. When I try to play games like Age of Mythology, Age of titans, Age of empires 4, the game closes after a while without giving any message, so please suggest! but when I am playing GTA III game there is no problem whatsoever. If I have to install Graphics Card which one should I opt for, my budget is around 5k. I am just a casual gamer and like to play only few selected games.
