We have an old HP desktop (maybe 4-6 years old). It has Windows Vista and an Intel Dual Core processor. Came home from work one day and it was frozen up. Turned it off,and it won't boot back up. When I turn it on,it goes to the screen where it says "loading windows" where it has that bar graph that goes back and forth,then goes to a solid blue screen,and won't boot up any further. I have a Windows 7 recovery disc that came with my HP laptop that has Windows 7. Can I use the Windows 7 recovery disc to repair my desktop?
