Sorry in advance for the lengthy post but i wanted to explain in detail my problem.
Okay, right now i feel like a computer noob. I downloaded the new Age of Empires 3 demo and played it. Before it started up it gave me a pop-up telling me that my graphics card may not be able to handle it and that it may cause corruption but i clicked to attempt to run anyway. The first time i tried to play it ran. The lighting effects were a bit off and it was a little slow but i was able to play. I played for about 2 hours and then closed it. The next day I tried playing it again, got the pop-up and it started to startup but then my screen froze. I hard shutdown(press the on button till it shut off) and tried again. It still didn't work and by this time I was starting to think I messed up my card. The game requires a 256mb card and I have a 128mb card. I have tried to reinstall the drivers and directx using the driver cd that came with the card but whenever i try to start a 3d game(secondlife, guildwars, etc.) the computer freezes and i hard shut it down. I fear that I may have overclocked and/or corrupted the direct3d part of the card. I went into the statistics thing and it said there were no problems but when i hit test direct3d it started to show a 3d cube and froze again. My brother tells me he has tried running mozilla but when he has more than one tab open at a time it freezes.
So, my question(if you don't need more info) is this: Have i utterly messed up my card and need to buy a new one? or can i do something to fix the card?
Thanks for the help,
