Hello everyone. A few days ago I've been having some bad computer problems with BSOD and Vista stuck on the Loading screen before Windows log in. I repaired Vista and have currently fixed though problems. However, I woke up this morning to my BIOS informing it me that it couldn't find my Hard Drive. This problem seemed to disappear with a manual restart. Afterwords Windows started up (seemingly) normally, however withing 10minutes of fully booting up (while using Google Chrome) I got an error which resolved in Windows freezing. The instruction at 0x707b2fc8 referenced memory at 0x707b2fc8. The required data was not placed into memory because of an I/O error status of 0xc0000185. Any help in this matter will be greatly appreciated and if you need any information that would aide you in helping my situation.
