Vista - I have problem starting up Vista - problem with driver

Hey there,

about a week ago i installed Windiws Vista Business. i noticed a couple of times that my [COLOR=#3676a2! important][COLOR=#3676a2! important]PC[/COLOR][/COLOR] jusr restarted itself. other than that it worked fine up until last night. it all started with intenet explorer. i couldn't open any [COLOR=#3676a2! important][COLOR=#3676a2! important]website[/COLOR][/COLOR]. it said something about corrupted file. so i figured i'll give it a restart. and then the it wouldn;t boot up anymore. it says that windows failed to start.... then it says:

file \WINDOWS\SYSTEM32\[COLOR=#3676a2! important][COLOR=#3676a2! important]DRIVERS[/COLOR][/COLOR]\acpi.sys

status 0xc000000F

windows failed to start because a critical system driver is missing, or corrupt.

i already tried to do what it said there. it told me to put in the original CD of vista and click on repair. well that didnt work. it was repairing over 18 hours and nothing is happening.

any suggestions? plz if u could help me i would really appreciate it, i have all my work, school stuff = pix on the harddrive i wouldnt want to loose that.

thanks

Tom

Sounds similar to an old xp thing with the acpi have you tried loading to a safe dos mode and running checkdisk with the appropriate parameters I think its "checkdisk /f /p" you'd need to run "checkdisk /?" just to make sure.
