Hi, I bought a new pc with the ASRock AB350 Pro4 but I get some issue.

My pc always boot correctly but reboot randomly when I'm getting in Windows 8 or when I have to type the password.

No crash occured in BIOS.

It seems to be something with my graphic card : a GTX Geforce 1060 6Go.

I try to get some informations with Cpu-Z in order to see something useful and I found my card is running on a 8x bus instead of a 16x 3.0.

The BIOS is up-to-date (4.70).

All frequencies & voltage are OK.

My 2x 4Go RAM Slot are well reconized, tested and OK.

Windows 8 64bit is updated and have the NVIDIA 1060 gtx last drivers.

CPU, GPU and MB temperatures are OK.

FANs speed are OK and functional.

I tryied to clear CMOS to avoid bios settings corruption.

The graphic card is on the first slot (PCIE2) and still crash on PCIE4.

I really think there is a problem with the motherboard because this don't crash when I boot on safe mode.

I really need you help guys,I'm distraght !

Thanks.

Did you install the latest AMD chipset (all in one) drivers?

If you check your event logs (in event viewer) under Windows Logs -> System and Windows Logs -> Application you should see an error message for whatever caused the reboots. You can filter the logs to only show error, warning and critical messages by right clicking the log (system or application). 

Let us know what you find in the event viewer as well as the answers to my questions above.

Hi Xaltar,

Theses reboots occur every boot, between 40 sec and 5 mins after login in.

This is quit random whatever I do.

I can't install All AMD chipset because of no windows 8 compatibility. And I can't install windows 7 driver neither.

If I could have more than 5 mins of boot (power on included) I will show you what the event viewer logs.

Thanks for helping me !

Hi, I got some news.

After reinstalling Windows 10 x64 I got a more stable system but not perfect anyway.

Windows event show me a "generic" kernel-power issue after every crash.

This can't me me anymore or the true reason of power failure.

Now my system is more stable and don't crash on desktop, I discover my CPU and GPU overheated. The first reason is my CPU (Athlon x4 950) auto overclocked itselve. I downgrade him to the standard clock voltage.

The second reason is My GTX 1060 didn't turn his fan correctly, I forced them with EVGA Precision to a personalized curve.

A finaly test these config with a burn stress test, both CPU and GPU during 1 hour.

This is better BUT this still crash with no reason.

win 7 64 bit driver for chipset

Ok guys, seems to be ok.

I don't know why but theses new crash only occurs with my game already installed.

So I reinstalled all my games and it's seems to be fine.

I change the topic to solved.

Thx for everyone, have a nice day !
