I just bought a Radeon HD 5450 for my computer its compatible with it as far as requirements go. I have 1.5gb of ram, pentium 4 3.0ghz, windows xp, 485w power supply. Everytime i go to install the drivers its gives me an error. If i try to install them from a website it says ERROR bad CRC something in your setup might be corrupted. I dont know what to do at this point hopefully someone can get back to me asap. Thanks
