MacBook Pro - problem with MacBook Pro 15"

im getting the white screen of death, and your probably going to shoot me for posting another white screen of death problem or for maybe posting this in the wrong place, i dunno.. sorry for both now if thats the cases

anyway, it froze and in a silly attempt to get it working again i just pulled the battery out and back in.. and then like magic.. the white screen of death

it doesnt give me a chance to boot any discs up,i have tried various keyboard combinations and resttting various things but all to no avail.

anybody got any other things that i can try, or is it a case of ringing apple or taking it somewhere to get it fixed.

oh and i dont have an OSX/Windows partication, i noticed alot of the other problems where caused by this.

help any1?
