This may help anyone who has had stability problems before with any Windows. I have experienced that using a single oversized drive as the Windows install drive doesn't work for me so if anyone has had this problem then I have a solution for you. Before I used to have a single 750GB WD HDD and I found that Windows Vista HP kept corrupting itself causing a wealth of problems with NO comeback or solutions available. I struggled reinstalling every couple of weeks which this went on for a few months , UNTIL , I discoverd using a smaller HDD for a Windows install and having a large HDD for other things (games and apps) fixed this unfixable problem immediatey. I haven't had any issues with HDD in last couple of months with this setup and now I am sharing it with you. I use an 80GB HDD for Windows and a 500GB HDD for games and storage. I can see now why they brought out SSD's for this reason.
