Since you told us nothing about your machine (make and model), after the machine splash screen, begin pressing F8 until you get the Safe Mode screen. Try Safe Mode and then System Restore, pick a date. If SM doesn't work, reboot, F8, choose Last Known Good Configuration. If no joy, holler back, there are major problems.
Tell us more about the new machine and the failing hard drive.
Drive = IDE or SATA?
New machine vacant ports, IDE or SATA?
Placing the drive into an external USB-2 case and accessing via USB.
My power source went bad and I am not sure what it did to my system as a result. I tried to do a system recovery and it keeps reading a disk error. I tried using a Windows XP disk and it shut down. I am soooo confused.
I need stuff off the old hard drive and someone said I could slave it to the new computer's hard drive, but I have had no luck trying that... partially because I am clueless what that all entails. Can anyone help?
