Suddenly shut downs and restarts.

hello everybody,

i will be as describable as possible for you guys but it will be a long text.
i7 4790k
asrock z97 extreme9
tridentX 16gb 2133mhz
corsair axi860 watt
2x r9 290.

Lets get this straight for you guys,

1) goin into bios and making a minor change(i didnt config any voltage or power related setting) followed by save settings and exit make computer like turn off and then boot up. (like when you oc your cpu and you play with voltages). Is this normal or common on this mobo?

2)when i hit restart button n my corsair graphite 760T the system instantly shuts down(like losing power,fans stop spining etc) for 1 sec then it boots up. Did i plugged case button wrong on my mobo or it's normal for that board?

The importand things now,

i did a fresh install of win 10 and i worked with my pc about 2 hours install win updates/activating windows and installing mobo/gpu drivers plus some drivers and software for my ssd,keyboard,mouse.So far so good,when everything done i installed driver booster 2 to automatically detect any driving missing,it found some and when the prog tried to install them the system froze for first time.
I rebooted and the system kept frozing after 5-10 mins of use. Logged into safe mode(totally 3 times with no froze) and unistalled it.
Then tried driver booster beta 2 cuz it says it fully supports win 10 drivers etc,samething happend,froze when tried to install drivers.
Logged into safe mode again and uninstalled it.
While doing all this (except in safe mode) my pc were shutting down randomnly and restarting.
I have no oc on my cpu.I tried bios default then boot,again either froze or shut down and reboot.

I dont know if it is a hardware problem (if i need to take off ram and clean it,swap dimms etc) or driver related.

Noteworthy Facts:
1)Right after win 10 installation before i install any drivers i updated my mobo bios,everything were fine but on my first restart the system froze. it could be caused by bios update OR it was the first sight of something wrong on my build.

2)today before i come at work i tried to run a benchmark on my pc to test stability and computer froze.So i decided to plug the second 8pin cpu cable (extreme9 has 2 8pin cpu sockets for extra voltage for extreme overclocking i think) to check if it fix the problem.After that i pressed hard all cables on my psu just in case any of those were not fully plugged in.I did the same with the cables on my mobo and the 24pin make a click like it wasnt fully plug in on one side.

Unfortunatelly i left for work w/o booting up the system to see if the problem was fixed.


I gave you all the information you may need and all that happend so you dont bother asking many question.

P.S driver booster 2 and 3 beta 2 are paid original versions.
P.S2 i used real temp and maximum temp reported was 55C so no overheating issue as well,no bsod as well.
P.S3 i have no fan attached on my "cpu fan" headers on the mobo, i have them connected on my controller in order to be able to config the rpms. is it possible to auto shut down in order to prevent cpu dmg cuz no cpu fan is detected on mobo?


Thnx you all in advance.
