Problem WindowsX

Dobrý deň mám problém pri pusteny PC mi naskočí modra obrazovka a píše mi toto:

A problem has been detected and Windows has been shut down to prevent damage to your computer .

UNMOUNTABLE_BOOT_VOLUME

If this is the first time you've seen this Stop error screen, restart your computer . If this screen appears again, follow these steps :

Check to make sure any new hardware aor software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problem continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode

Technical information:

*** STOP : 0x000000ED (0x8ADE0900, 0xC0000006, 0x00000000, 0x00000000)

Problém s PC sa mi vyskytol prvý krát a mam Windows XP. Dalo by sa to opraviť a ako ??

Ďakujem
