my home pc is a hewlett packard/ genuine intel r cpu 2140 @ 1.60ghz / 32 bit operating system.. the back of the computer is free and clear, audio files play fine. i have not downloaded any codecs. everything has always played with windows media player with no problems. usaully if i have a problem i close the player and open it back up and its fine... i dont know what video card i have but i think its only 64 bites? because when i downloaded shadowrunner it said i needed 192 or higher... what kind of video card should i buy????? i am very new to this but am very determined to figure this out. i dont know what resolution i'm using factory settings i guess
