I have a semi-old Asus g50v laptop that I bought when I started college. A few months ago I started noticing that my windows files were slowly becoming corrupt. At first I tried to run checkdisk but this was a no go since chkdisk or autochk had become corrupt and wouldn't load at the start of windows even using msconfig to boot with a minimal boot. So then I tried running sfc /scannow and it would keep saying that it couldn't fix all the files. Eventually when I stopped being lazy I formatted the drive and reinstalled windows but corruption began again shortly after. so at this point I felt like I had enough hard evidence to replace the drive. I ended up replacing it with a seagate momentus. So then windows 8 comes out I upgrade to windows 8 and now windows keeps telling me in the action center to restart to fix corruption. Like before autocheck never kicks in at the start of windows. So at this point I'm scratching my head as to what the actual cause of this problem is? Could this be psu related? Any suggestions would be appreciated.
