Repairing your computer does not always require the services of a costly computer technician. Most problems on today's operating systems can be solved by using the System Restore feature you already have at your fingertips. Be sure to back up files beforehand; some features will erase data files. Refer to your user's manual for further details.
Click "Start" and type "System Restore" in the "Search" box.
Press "Enter" and select "Use a different restore point."
Choose a date prior to the time your computer first began exhibiting problems.
