I installed a new HD in a Dell Inspiron 1720 running at 2.2Ghz with a Intel Centrino duo. I tried reinstalling the Operating System (Original Reinstallation DVD Windows Vista Home Premium 32BIT) DVD that came with the computer but the three times I have tried to install it stops at the "Completing Installation" part of it. It goes to about 80% of the installation bar at the bottom of the screen and then stops. I left it running overnight at that point, thinking that it would eventually finish but the screen went black at some point during the night. I have partitioned the disk in an attempt to see if that did it but nothing changed.
