This computer is about a year and a half old. My dad built it, and he's built a couple computers, so I trust his work. I know it has an AMD Athlon processor, a pretty high end ATi video card, 2 ghz of ram, etc. I can get all the part specifics later if that's needed. Basically what happened with the PC is during video game play, my dad would get a blue screen, and he found that the computer said that there was a hard drive failure. He would have to perform checkdisk to get it running again. This happened a few times. It even happened when he opened up the start menu..again, just a blue screen. He tried 2 hard drives, both of which were completely fine, and still got the error. He took it to Best Buy to have their techs look at it, and all they told him was it was hard drive failure. Well, he bought a new computer, and gave me his old one to try and salvage it since my old computer is pretty ancient. I did a fresh install of XP, everything was fine, then I rebooted the computer, and now it's not regognizing a hard drive, and obviously, it says that Windows has not been installed. Should I start out fresh with a new motherboard?
