    I received my Bolt V8 (purchased from Mouser) last week, It worked OK in past few days.

    Just a few hours ago, when I tried to install AMD V-Series driver for Windows, the blue screen pop up.
    It does restart the system to BIOS logo after the blue screen happened.
    I noticed that the FAN didn't spin, so I entered the BIOS menu tried to tune the FAN control.
    After I clicked "save and exit", my Bolt V8 never shows the BIOS logo again.

    Symptom:
    When I pressed the power on button, the power LED turns to green but it transits to amber in 2 seconds (and it would automatically restart the same behavior again and again). No image shows on my HDMI monitor.

    Environment info:

    The add-ons I had attached to my Bolt:
    • 2 * Kingston DDR4-2400 8G RAM (KVR24S17S8/8)
    • 1 * ADATA XPG SX8200 Pro 512GB M.2 2280 PCIe SSD
    • 1 * Intel 3165NGW Wi-Fi module
    The failed attempts I tried to make it back to work:
    1. Checked the PD trace, confirmed it's negotiated to 20V@3A profile (adapter is capable of 20V@4.5A) - see attached pic
    2. Switched to DC power brick (Dell laptop's power adapter - 19.5V@6.67A)
    3. Removed SSD and Wi-Fi module
    4. Unplug CMOS battery and plug it back after 5 sec.
    5. Tried to connect only one RAM on the different slot (2*2 combinations)

    I was thinking about the compatible issue of RAM. But it seems not able to explain why it worked just fine with them earlier (average 5+ hours up time in every weekday before it happened). And, I don't have spare RAM to give it a try.

    Any idea?
