This particular desktop was loaded with windows Xp proffesional. This morning when the machine started it showed a Blue screen of Death with the message "Registry Failure". shut the machine and tried to restart in safe mode but machine freezes.
Step 2 - Tried repairing the OS with the original CD , but for some reason on the repair screen menu it does not recognize the os and wants to do a fresh installation.
The onlly problem there are custom program which will be lost with the fresh install.
