With the average modern computer using some very tiny electronic parts and running some very complicated operating systems (all to make life easier of course :) Alot of things can go wrong, be if from malicious files like VIRUSES or SPYWARE to catastrophic hardware failure (a dead hard drive means you loose all your files!)

• Computer running slowly
• Strange messages constantly ‘popping’ up
• Strange websites loading
• Your internet usage is high even when you dont use it
• Grinding or clicking sound coming from case
• Whirring sound from case
• Excessive vibrations from case
• Bad smell emanating from case (Dangerous - turn off system and remove power cable from wall)
