I have an 8gb HyperX fury 2x4 installed and it was running normally on a dual channel mode . . .
suddenly PC shuts down and resets and then my PC only recognizes 4gb but then on AI Suite and CPUZ it detects both sticks and im running on 8gb 1866mhz but on a SINGLE CHANNEL

what could have went wrong?
tried switching the kits on A1 and B1 then on A2 and B2 slots same thing...

tried putting one stick at time both are perfectly fine . . . .

That is really weird, haven't heard of this before but will do my best to help.
Have you re-applied thermal paste recently or played around with the CPU cooler recently?
Try resetting the CMOS
You said the issue occurred after a random shut down, go onto your event log and check what was the cause of the crash
