Htc Evo bootloader

[geeks6800]

hello all

well I posted earlier but no response so far did a couple of searches but unsure what to do. I have been unsucessful with pc36img. So tried fastboot in bootloader menu but nothing i am using a windows 7 pc. So i changed over to windows xp machine...attempted to flash a RUU and succeeded. but again within minutes the phone froze and i reboot and stuck on white screen. tried again to reflash but as the RUU attempts to reboot the phone into bootloader it phone shuts off and will not come back on without removing the battery . Is there a way to reflash the bootloader. here is the specs on the phone:
