The computer wouldn't boot. After some troubleshooting I found that it was the HD. It failed the DFT advanced test at 26%.
So, I imaged the drive onto a new hard drive. I backed up all the data at this point.
I'm still not able to wipe the HD and restore Windows. Sometimes it gets stuck at the part where it's loading Windows from the CD. At other times it gets through but gets stuck at a blank screen with a blinking cursor. Other times the monitor flashes random characters and symbols.
Does anyone see what's wrong here?
