So, the other day I uninstalled my ati display drivers, planning on reinstalling them because they were acting up. I restarted my computer, and I'm now using the "Standard VGA Graphics Adapter" (according to device manager). I've tried reinstalling the ati display drivers from the website, but for some reason, it just doesn't work? I don't think my computer recognizes that I have a video card -.-. Any solutions? Not having drivers makes me unable to play any games on steam, they launch, and then close right away. Portal 2 will be out any day now, I already pre-ordered it. I'll be really angry if I'm not playing because of stupid drivers. I've tried several solutions, but to no prevail 
I'm using Windows 7 Home Premium 64-Bit, graphics card is Ati Radeon HD 6570, if you need more info, ask.
EDIT: After installing display drivers from the ati website, they don't show up in device manager, and the screen does not change, leading me to believe it doesn't recognize my video card or something.
