alright well i bought my freinds old computer for $40 bucks, its a 2003. I'm guessing that it's custom because the outter case has no markings on it. it runs on an intel processor and the graphics card is essentially built into the motherboard. i have multiple problems:

1/2 of the time i turn the computer on, i get no response from the mouse or keyboard.

on my first attempt to play silkroad on this computer, it said that i didnt have the most recent graphics driver, so i managed to find it and download it, but now when i try to start up sro, it doesnt tell me that message, it just opens up the little rectangle and than stops responding.
i am wondering if i could upgrade the ram for this computer because it only hase about 512(only detects 484 though...) but i dont know how to find the right ram because i dont know the make of the computer. please, if youre a computer wizz and can help me out, please do so, it would be greatly appreciated.
