Random Restarts

Couldnt find anything that sounded like whats happening to me.
(Sorry if wrong place)

For a few months now I have been getting "random" restarts. There seems to be no connection between any of the restarts. One minute I could be on desktop, the next I could be on the Internet. Some days I have no problems at all, some days I can get over 6 restarts in the space of a few hours.

They never left a blue screen even with the settings turned on. The PC was reformatted and it seemed ok for a few days but then it begun. Still no blue screens until now.

(CANT ATTACH YET FOR SOME REASON )

interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: c643a09e, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: b7eca198, address which referenced memory

As a PC newb... I have no idea what that means which is why im asking for help please.

Edit 1: Still cant attach the button doesent appear, maybe something is blocking it . Also, the blue screen may be completly unrelated to my "random restarts" so any info would be grateful.

 

Also... (event log)
