Freezes on lockscreen?

[wmphoto]

So, my phone freezes on the lockscreen. Sometimes I can get it to unlock after 5-10 tries of cycling the power switch.... Sometimes not.
I figured it was the rom... changed them quite a few time, even back to the stock a few times always task 99 before re-flash...
Then thought it might be one of the programs I'v been loading... nope does the same thing on all of them...

Last night I installed the Windows 7 rom, unlocked it for the live services and low and behold it starts doing it again....
Any idea... is this something that anyone else has run into... I would assume hardware at this point...

Thanks,
