Hello friends. Greetings to all. I lately upgraded from 2002 XP Pro to Win7Pro and moved the data from XP to 7. Installed original software - Office Home & Business 2010, Quickbooks Pro 2011 and Adobe Acrobat Pro X. Now, when I cut and paste .pdf files using the right mouse click, Windows shuts down. Also, there are large number of issues with monitor display. Guys please help and let me know why such a thing is happening. Really irritated. Thanks in advance for the help.
