BSOD - Not sure what's causing it

[Drake5]

I left my PC on last night and it restarted - Checked error log which showed the The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Is their any way I can find out what's caused this

Whas there a STOP code associated with the log?

Any windows error dump files?

Bluescreens happen from time to time. I really wouldn't lose any sleep over it or spend much time trying to find the cause.

If it starts happening more regularly then it might be worth investigating

It says 'bug check name' IRQL_NOT_LESS_OR_EQUAL and bugcheck code '0xA'
