I have a major problem. My sons computer keeps losing its hard drive. I have gone into the BIOs and reset it to Default but then it lost the Hard Drive completely. I had checked before i rebooted to see if it was reading and it was. I set the BIOs for PnP in hope that it would find it but now all it does is sit at the loading screen and i cant even get back into the BIOs to try something else. What is should i do to maybe correct it.
