Stuck in TITAN bootloader? Read this!

Ok, so let me add my bootloader issue to the mix... Flashed a ROM, phone worked great for a few days, and somewhere in the night, it reset itself to the boot loader screen. if i leave the SD card in, it will continue to loop and reload the Rom, if I take the card out, it will get to the bootlader screen. When i plug it in to my pc (xp sp3) it gives me the old "one or your usb devices has malfuntioned...yada yada) and i cannot run anything from the PC. Things i have tried;

re down loading all associated software, include async and htc drivers
flashing stock rom
12,000 hard resets and 2 million soft
swearing

Anyone?
