Why cpu getting on after few minutes

[Amirdhavarshin]

After having the main switch on, the tower only after few minutes (atleast 5-10 minutes) gets the power supply to run the system - This happens often whenever I use the system after few days or use it for long hours - Pls help me to trouble shoot..
