Graphics Issue.

[BitterReality]

K, so I'm saving up as of now, for the next probably 10 weeks for a new graphics card.
I need this, because I can't install anything over OFB because the walls flash red.
I've been told this is the fault of my graphics card and I need a new one
BUT
I don't know what my card is in the first place, OR what I'm gonna need to buy.
Any advice?  {blink}
I'm sorry in advance, cause this is so loosely put together.
I hate my stupid computer  {cursing}
