Default [Q] Unable to restart phone

Hi guys,

Hoping someone here has the knowledge to help with my little problem!

My phone battery died a few days ago. When I got home to recharge I found the charging LED wouldn't show and also the phone wouldn't restart.
After several attempts I resorted to flashing the ROM again. I got it up and running, but then again by restarting manually again the phone went into a bootloop and wouldn't start up.

Has anyone experienced this before? I've had no issues previously but this is really starting to bug me. Means I can't run Xposed modules etc that need a reboot. I've now installed the ROM 3 times and tried clearing the cache after each.

Running ARHD 51.0 with stock kernel.

Many thanks in advance!
