Usually BSOD indicates an incompatibility between your hardware and Windows (ie. driver problems) or a hardware fault/error.. If you always get the same errors at the same point, then it's more likey to be a software error.. Has it ever been stable in its current configuration - often this situation arises after you have reloaded Windows, installed new hardware/software, updated your system etc.. Try the following..

1) Go into your laptops BIOS and select "Safe Settings" or "BIOS Defaults" or whatever..

2) Set your SATA controller to "compatibility" mode if applicable..

3) Boot Windows into safe mode if you can..

If the computer runs ok in safe mode, then it's likely a driver, service or software issue.. Try removing/disabling items one by one (starting with the most recently installed) to see if you can isolate the problem. Try booting your computer from a Linux "Live CD" - plenty available to download free - and see if everything operates correctly..
