Website loads a blank screen

[kalu]

Hi
Am new here. Could somebody direct me on what to do because my website has been loading blank pages for the last 24 hrs. I have not messed up with the code so it is definitely not a code related issue.
I use cpanel linux based shared server and i contacted my hosting company but they have not been able to help me.
