I will have to know more information to help you solve it.
Alternatively:
Hook your HDD to another computer or boot a linux or mini xp from CD/USB to rescue data or edit your files.*
If you have a Windows CD you can boot up on that and access command.
Read up on "bootrec".*
I'm afraid a fresh install of Windows is your quickest and easiest way to go.
*Some computers require you to go into bios from boot to change boot device priority or allow you to use a boot priority start up button (F12 etc.)
There is no "registry" on a motherboard. The Windows Registry is stored on the hard drive.
The windows registry. Technically in the file system.dat though you cannot directly edit this file
Yes. All data on the hard drive will be destroyed, including the Windows Registry.
The best one is definitely a reinstall. You can how ever try booting a operating system from DVD to access your files. A few repairs can also be done by booting a Windows 7 DVD. Read up on "bootrec".
One is hardware, one is software. OS/X (Mac) has no such thing as registry, so 'the registry' is software and is a main point for operating system info about a windows 95 to Vista install. A bad hard drive is a physical error in the hardware and cannot be fixed by reinstalling anything.
Yes you can.
There's a lot of things that can cause a BSOD. Registry errors, programs causing conflicts with Windows or your driver, out of date drivers causing conflicts, corrupted RAM, or even your hard drive starting to die and corrupting the information stored on it. Unfortunately there is no one answer to the question.
It is stored in memory until windows shuts down. The logical location (on the Hard Drive) is system32/config
When Windows won't boot because of changes made to the registry, you can copy the correct registry files back onto the hard drive.
If you are asking this question, preferably you should not even try to edit your registry! Editing the registry manually can even stall your system if you don't know exactly what to do. In case you want to give a try anyway, here it is: Start > Run > type 'regedit' (Enter)
When using windows, if you install programs and then subsequently uninstall them, you will often be left with registry errors in windows. These errors can often slow down the performance of your computer. By using software to fix this you can very often free up some hard drive space and improve your computer performance.
You can manually go through the file structure and the registry and delete the files and registry keys belonging to the program. You can usually find out which files to delete and where they are by searching "manual uninstall [game name here]".
