I have an issue where one of my old PCs is not posting without pressing reset. It has been around for sometime and finally getting back to try and sort it.
Description:
Asrock 870 extreme3 will post immediately to dr debug code d0 (every time). It can be immediately remedied by pressing reset whereupon the system will post normally, every time.
Happens whether on first start or reboot (ie whether it is warm or not).
What I have tried (over 2 years so may be out of order) -
Recently added upgraded to windows 10 . no changes to symptom.
Current setup is
Any insights on what the issue might be would be much appreciated.
I would especially like to know what the differences are between a hard reset (hold power button) and just hitting reset. ie what does hitting reset actually do?
Cheers,
Mcgyvah

What I have tried (over 2 years so may be out of order) -
- Replaced power supply (twice) . Both seemed fine- no change in symptom.
- Reseated/check cpu multiple times and used cpu with a different mobo with no issues. No changes to symptom.
- reset cmos (many multiple times) replaced cmos battery, reflashed bios (this has been done using 3 different methods on asrock support page). No change to symptom.
- Checked all connections and for hair /debris in mobo which has been removed/cleaned etc)
- different peripherals used.
- ensured cmos button not jammed in or anything similiar ( found someone had that issue somewhere on google).
- Have also swapped out ram and tried different channels.
- removed headers and just operating on mobo switches ( no changes)
- Tried many different bios settings.
- Used different GPU.
- used different hdd's
- Probably done other stuff I cant remember.
Recently added upgraded to windows 10 . no changes to symptom.
Current setup is
- Asrock 970 extreme3 on basic bios settings
- Phenom ii 555 black default clock, UCC off.
- generic 8gb ram (works fine/ also tested in other PC)
- ssd 550gb OS windows 10 (new)
- HDD x 2 in raid 1 2tb
- Backup HDD x 1 2tb
- GPU is Asus GTX 660 directcu ii
- Corsair CV650 (new)
