I just built a new computer. I've got: AMD quadcore Athlon II processor, Biostar A880G+ Micro ATX MB, Radeon HD 6570 video card, 500g seagate HD, and 8 gigs of ram I just installed Windows XP 64 bit on it because it's the only 64 bit OS i have. Everything went fine in installation. But when I insert my drivers for the hard drive and video card it tells me "D:/ is not a valid win32 operation". It wont even recognize the disc when i insert the MB driver. Any assistance would be much appreciated.
