Hi, Check the power supply if it's turned on.
There a test for power supplies using a paperclip. Connect a fan to a molex and see if the fan is spinning.http://www.youtube.com/watch?v=5FWXgQSokF4[/quote
Hey and thanks for your response, I just performed the test and it didn't work. So it's my PSU that isn't working? It all worked perfectly yesterday:(
