On a Dell Inspiron laptop, the mouse buttons are sporadically erratic, either not working, both buttons working as a left click, etc. This also happens when you use an external mouse, so it's not the physical keyboard. Have run AVG and Malwarebytes, no problems found.
This laptop was shipped with Vista, with a free upgrade to Windows 7. I've been unable to find a cure, so I'm planning on wiping the computer clean and reinstalling Windows 7. I know the general process, but I have two concerns:
- The laptop does not have a CD drive, you have to use a USB external. After formatting, is the USB CD drive going to be recognized? If not, how to I get around this?
- Since it's an upgrade, I'm concerned that the Windows 7 will not install unless it sees an existing copy of Vista. I think the original Vista is part of the problem. Any suggestions?
