Likely it was Malware which slowed the computer and prevented the reinstall. Ubuntu has a better format than the Windows disc hence wiping the Malware and thus allowing the install. DBAN is Darik's Nuke and Boot and is a utility which securely wipes the hard drive of all data. It essentially is the most through free format and I advise using it when its a Malware issue has been suspected or the computer is being given away or sold.
I am having great difficulty doing a clean install on my laptop. I have run all the Diagnostics. I have the original install disc and I have even tried the Win7 Iso from microsoft. Thinking maybe the install disc was bad. When I do the install it goes through all but the last step. It reboots to resume setup. But it only continues the install for a few minutes before it gives a BSOD. It then reboots and when it is done rebooting it says the install cannot continue. This happens every single time. I have been working on this for over a week. I have no idea where to go from here. I have no idea what I may be doing wrong. I am pretty good with computers and have never had trouble doing an install like this before.  I would greatly appreciate any help Bill
