First of all, let me start with details on my build.
Motherboard: ASUS Z97-PRO LGA 1150
CPU: Intel i7-4790K
RAM: G.SKILL Ripjaws X Series 16GB (2x8GB) DDR3 1600 (PC3 12800)
PSU: Rosewill CAPSTONE 650M 650W Modular Power Supply
GPU: MSI GTX 970 GAMING 4G
Cooler: Noctua NH-D14 (fan)
OS: Windows 10 Pro x64
So on with my problem... I've been using this PC for the past 3 years and around 3 months with little to no issue. However, recently I've experienced the PC not booting up nor even letting me access UEFI after a restart (the restart is usually caused by a W10 update). One time it happened, I just reconnected the GPU and it booted just fine. Unfortunately, it wasn't the same this time.
As of now, I've tried the following things. Alongside each item, I will state the result.
* Default setup:
-- MB has code A2 (related to hard drives?)
-- MB has BOOT_DEVICE_LED on
-- black screen, won't go to BIOS
1. Removed GPU
-- didn't solve it
-- MB still has code A2
2. Removed SATA cables
-- didn't solve it
-- MB has code 99 (related to PCI Express I think?)
-- MB has code A2 if at least one SATA cable is connected
3. Removed USB drives
-- nope
-- MB still has code 99 with SATA cables removed
-- Code A2 with at least one SATA cable attached
4. Left one stick of RAM
-- nope nope
-- Still shows the respective error code depending on the SATA cables connected
5. Reset CMOS
-- nope
-- removed battery, did the ASUS instructions involving the pins... no luck
Right now, my PC is at bare minimum and it's still showing the same symptoms. I initially thought it was the GPU (because my GTX 970 started showing factory defects past warranty period), but removing it now and the PC still not working seems to be proving otherwise.
I just want to know if this could potentially be a motherboard problem so I can decide if I should buy a replacement motherboard now. Should I try other things? I need my PC for work so I really don't have the luxury of time.
Lastly, what happens to my Windows 10 if ever I replace my motherboard? Will it get deactivated since it's on a "different machine"?
That's all for now I guess.
Thank you!
