PC Buff will help you get over a problem with respect to your computer not working correctly, such as:

My computer doesn't work:

• When the computer is switched on, nothing happens
• Programs that used to work are no longer working the same (or at all)
• Inability to connect to the Internet 

My computer is slow:

• The computer seems a lot slower than it used to be
• The computer seems to take an unusually long time to start up

My computer is unpredictable:

• When in use, the computer suddenly stops
• Unexpected things happen for no apparent reason
