HTC 8X Sudden Reboot/Hardware Fault URGENT!!

[WillQuinnHTC8X]

Hey Guys, bit of an emergency. My HTC 8X GDR3 is randomly powering off and then getting stuck in a reboot loop. After several runs in the boot loop, the device will power on to the lock screen, allowing me to sometimes get in. However, mostly once it reaches the lock screen it goes straight to the slide down to power off and will not let me return to the lock screen and after about 10 seconds the device will power off and reboot and do the same cycle. My phone did come into contact with a small amount on water at the lock button area during a rainy a day, however the phone functioned normally for about 6 hours afterwards. I am now unsure whether it's a hardware fault or a software corruption.

ALL HELP IS GREATLY APPRECIATED

THANKS
