Hello everyone,

yesterday my Desktop was crashed out
and i suffer with the BSoD..

Stop: c000021a {Fatal System Error}
The Initial session process or System process terminated unexpectedly with a
status of 0x00000000 (0xc0000001 0x00180a58)

Collecting data for System crash dump..
initializing disk for crash dumpp..
begining dump of physical memory..
dumping physical memory to disk: 0-100%..
Physical memory dump complete..
I search over the Internet to Find a solution..
i ran sfc/scannow but nothing was wrong..
and before i do anything else i just ..
Unplug and plug again the power cable..

..And everything went back to Normaly..!
i don't know how is that posible!

When the windows start up and logged in
a pop-up cames up telling me about the Error

I get those dump files because i am not sure what it will happend
if i am going to restart my pc..
maybe the Blue Screen will came back again.. who knows..

so can anybody check them and see if something is wrong?
should i have Reason to worry?

Thanks everyone!
