Ok, let's start from the beginning.
I recently made several upgrades to my PC but kept the same motherboard, RAM, and CPU which are:
- MSI Mpower Z87
- i7 4770k
- 2x8gb Adata DDR3
This build ran flawlessly for a couple of years but I recently switched cases and at the same time I switched out my 780ti for a GTX 1080, I also added:
- 2tb Seagate HDD
- Elgato HD60 Pro (PCIe)
- TPLink AC1900 PCIe Network card
I also switched out my unnecessarily large Corsair AX1200 PSU for a Coolermaster 650w.
The system boots fine, it seems to run fine, but the debug LED codes rotate like clockwork on every restart.
I will boot up and once I'm in Windows it will read "A0" which the debug LED table doesn't specifically list though it could mean "Onboard devices initialize and detect" - I am lead to believe that this is normal but I was sure that it used to simply read "00" prior to the changes.
The next bit is the strange bit though, because the next time I boot up it will read "04" which is listed in the debug table as "Power on South Bridge Initialization".
The debug codes rotate, from A0 to 04 on every restart, in both cases the system appears to run fine but it still concerns me and I couldn't find anybody with a similar problem, I've switched PCIe slots for the devices, unplugged devices individually, switched the RAM slots, I'm not sure where to go from here.
I should also add that in total for storage I have:
- 2x Samsung 840 EVO SSD
- 1x 3TB WD Black HDD
- 1x 2TB Seagate HDD (Recently added)
