So today I was having trouble connecting to a wireless internet network and decided to restart my computer. In the process, it was taking a long time so I turned it off using the power button. When I turned it back on, everything went on as usual (except for the screen at the start telling me the computer had not been shut off properly; I chose to start windows as normal). After I came to the log in screen and entered my password to login, the screen turned black but I could still move around the mouse. I left it alone for a while but nothing had happened. How can I fix this?
I'm on Windows Vista Home Premium.
Thank you!
