Reboot without Bluescreen

[Assasin_Cross]

Hello, I'm currently having issue with my system.

My rig is

Proc: Intel i3-530
RAM: Team Elite 2x2GB@1333Mhz
Motherboard: Gigabyte GA-H55M-S2
Graphic Card: Gigabyte GTX 750Ti Black Edition
PSU: Seasonic G650

My issue is during GPU stress test it worked fine but if I change the window to another application or trying to end the stress test, my system suddenly reboot without having BSoD

I suspect it Motherboard, Graphic Card , or PSU issue but I still dunno...

Turn off autorestart and you'll get your BSOD.

Turn off autorestart and you'll get your BSOD.

Nope didn't get any BSoD
The system just went off and restarted itself

turn the pc on, select the boot menu, turn off automatic restart on error.
if it doesnt bsod then i would assume its something to do with your power cutting out rather than a windows fail.

error 41 just means your pc lost power. either by a random reboot or the power went off.
you need to be looking at the errors just before the error 41 if there are any.
