1. That PSU is a quad rail reviewed at http://www.tomshardware.com/reviews/power-supply-silent-passive,3189-2.html
It would be too easy to overtax a rail and get odd reboots.
2. I can't tell if you installed the OS after the changes. Windows tends to crash on hardware changes.
It's one or the other from the story told. Too bad the PSU wasn't a single rail as there are enough Watts. You might be able to eek by unplugging what you can from the +12V connections. Unplug second drives, that Optical drive, what else?
So i recently upgraded my PC (see below) and now it restarts (it shuts down like its a force shut down, but then restarts), like 1 to 2 mins after i boot it up. This doesn't happen when i boot him on safe mode or if i just chill in the BIOS.
GPU: Gigabyte Nvidia Gtx 970
CPU : Intel Core i5-3570K ---> upgraded to i7-7700K
RAm : Hyper X black DDr3 1600 (2x8Gb) ---> upgraded to HyperX Fury DDr4 2133 (2x8Gb)
Mobo : Gigabyte GA-Z77N-Wifi ---> uprgraded to Ga-Z270N-Gaming 5
PSU : bequiet! Straight power e9 480W
CPU cooler: bequiet! Shadow rock pro sr1 150w TDP
OS : windows 10 pro
What ive tried so far:
-Still same problem after running only with onboard Graphics (removing GPU)
-Still same problem after runnging with only 1 Ram stick (tried both in both slots)
-Ram voltage correctly set in Bios (1.2V)
-Still same problem after resetting CMOS
-I have no speakers in my Tower so no BeepCodes
-nothing seems to be overheating
Now to the funny/weird part;
i tried to test my Ram with memtest and it turns out while I have memtest running my PC doesn't shut down then immediately restarts, but immediately after i close the program it does it again.
I hope someone can crack this mistery that ive racked my brain out trying to solve.
Greetings and thank you for the answers.
