Windows 7: My pc crashed today first time ever during startup

Couple days ago i made a topic where i told my friend is having crashes on startup.
Well that problem is already solved.

Today about half an hour ago when i rebooted my pc it loaded just fine until boot animation but just before entering windows screen goes black and screen popups message "No signal". After that windows reboots itself and boots normally into windows.



I tried to check with nirsoft bluescreen viewer if i got blue screen but apparently it doesn´t show any crashes. D:

i will include my SF-Tool information as an attachment into this topic.
My specs can be seen below of this post.

anyone? D:

Most probably that "no signal" message came from your monitor. When the computer is idle, but monitor is powered on, this message appears.

Apparently nothing to be worried, but if it recurs, let us know.
