Losing Access To pfsense

[jnic]

Since I have upgraded pfsense to version 2.4, ive been having some issues.
The other day i couldn't access any sites that used HTTP, so then i tried to access the web UI and could not, i tried to SSH into it, and physically plug a monitor and keyboard into it but all i got was a blank screen I could type into, So i ended up having to pull the plug on it, once i restarted it it worked fine, until today when the same thing happened

I have attached a picture of the notifications i got after i restarted it.
