Default [Q] 5 minutes black screen then 5 minutes white screen with htc logo

Anyone seen this problem before and know solution?

I turn on my Phone and have to wait 5 minutes before it goes to the white screen with the htc logo.
Then it stays on white screen with htc logo for another 5 minutes.
After that the Phone starts booting and works normally.

This also happens when i go to bootloader or recovery.

During the 10 minutes waiting time the Phone gets very hot and battery drains quick

Hope someone has any idea's.

Have search for weeks now but not found any solution yet.
