theres no crashdump it doesn't reboot it just freezes! screen stays black, but keyboard screen stays lid which means it didn't reboot.
i tend to believe that i have a faulty cpu. i'm going to try the segfault bug script tomorrow. ]]> Tue, 03 Oct 2017 08:56:46 +0000 https://forum.asrock.com/forum_posts.asp?TID=6235&PID=37270&title=dr-debug-90-on-system-freeze#37270 <![CDATA[dr debug 90 on system freeze : Zwu, your specs are too sketchy...]]> https://forum.asrock.com/forum_posts.asp?TID=6235&PID=37268&title=dr-debug-90-on-system-freeze#37268 Author: MisterJ

Zwu, your specs are too sketchy to be useful to the memory experts.  Perhaps your system crashed (BSOD) and was trying to re-boot.  Please look in the Windows folder and see if there is a minidump folder and if so, compress it and upload it to a site we can DL it.  Thanks and enjoy, John.

my system is in the sig, what else you need to know?
i have 4 or 5 sdds and 1 hdd, 1 bluray drive, a 290x AMD GPU. win10 pro

temps are not an issue, it idles around 33C

i have found that postcode aswell, but it tells nothing.what does it mean?

after boot it shows cpu temp.
90 is only shown when system freezes. ]]> Tue, 03 Oct 2017 06:45:38 +0000 https://forum.asrock.com/forum_posts.asp?TID=6235&PID=37266&title=dr-debug-90-on-system-freeze#37266 <![CDATA[dr debug 90 on system freeze : Zwu, 90 - Boot Device Selection...]]> https://forum.asrock.com/forum_posts.asp?TID=6235&PID=37264&title=dr-debug-90-on-system-freeze#37264 Author: MisterJ

Zwu,
90 - Boot Device Selection (BDS) phase is started

You have told us nothing about your setup.  Please post your specifications as I have in my signature.  90 is a progress code.  Please make sure it is not the last code remaining at the end of a normal boot.  Here is link to the codes:

Enjoy, John.

hi guys,

sometimes at night or longer system inactivity my pc freezes (sometimes with fans full on) .

the debug led says 90 and i have to push reset on my pc.

windows eventlog doesnt show anything besides an unexpected shutdown occured

my cpu is on auto (stock) settings
ram on xmp 3200 (soc :1.15v)

its not a reproducable error, happens like once a night,


maybe the error code can contribute to a solution. but i cant find out what it means.
