    Everything seems to be normal, every fans are spinning, motherboard's led is working, power button is working fine, and the button on my blu-ray disc rewriter is also working
  3. Even if your Motherboard is dead, the things you describe could be working.
    I'd test if the monitor itself is ok, by connecting anything to it (sometimes people have other devices to connect, like i.e. a digi-cam).
    Then, use another cable (lend it from a friend for an hour or so).
    Then, use another port of GPU and monitor (which requires i.e. a Displayport-cable if you normally use HDMI, or vice versa). Again, don't buy a cable, lend it.
    Then, check if you can connect your grapjics-card to another PCIe-power-port and cable, in case the 12-Volt rail is damaged. That would mean your PSU is rife for exchange.
    Then, if another PCEe-slot existst on your board (very likely, but i didn't check your manual), try that with your GPU. If that helps, your MoBo is damaged.
    You could test then with another GPU, but, really, i almost never heard of the GPU being broken. It's possible, but really unlikely. Test that last, if all else does not give an indication.
    At this moment, a dead motherboard is the most likely culprit.
    Start with whatever test from this list can be managed by you (get assistance, if needed), and report back.

    yes, I agree with you. The motherboard is working very strangely even before this happened. This is a new built pc, I just finished building it last week, when I go to the motherboard setting to change the mhz for rams and other things, it would failed. When I restart the pc to save the settings, it would turn on and off three times before it actually turn on and the setting remained unchanged. It was a new motherboard too, bought it off Amazon, never going to buy another ASUS motherboard. RIP $160
  5. May or may not be Asus fault. It's a Ryzen. When Ryzen first came out there were multiple issues with Ram, especially the SkHynix used in the Corsair lpx. You bought the board from Amazon, but there's no telling exactly when Amazon got that board. So it's entirely possible that the bios is having fits, especially when you try messing with ram frequency. You don't restart the pc to save bios settings, restarting the pc with settings that make the bios/pc unstable will result in power on/off according to bios reboot settings until the bios hits the set amount of reboots, at which time it'll revert back to the last stable settings. You just use F10 to save, but the bios will still revert if it's not viable. In your bios, the # of reboots for OC settings is 3.

    First thing, reset cmos.
  6. Karadjgne is right.

    This comes after cmos reset. Do not apply any user OC or other settings to the bios prior to use, leave the bios alone other than what's absolutely necessary to get pc to function. So no ram frequency changes etc, just need viable access to a working bios.

    This'll fix as many ram and other issues as Asus has with Ryzen cpus. Once done, and you've rebooted successfully several times and OS is stable, then you can start adjusting, slowly! Do not just jump into settings you want, you have to give the pc time to adjust to new settings. OC to levels you want can take weeks of adjustments and testing until you get it right. Do not rush this.

    by restart i mean, i use F10 to save and it restart automatically.i change the ram frequency because the ram frequency was 2400, which is far below what my ram is capable of, anyway, how do you reset cmos?

    Answer in above post.

    To reset bios/cmos is easy. Unplug the power to the pc. Push and hold the power button for @10 seconds (drains residual power in the motherboard). Open the side of your case. Somewhere near the pcie x16_1 gpu slot (often right underneath that gpu) is a large watch battery. This is the battery holding power to the cmos/bios memory. Remove that battery carefully. Count to 60ish. Put battery back in, close up the pc, plug power back in. By removing the battery, the cmos/bios memory is wiped, causing the bios to revert to its factory preset. Any and all changes made by you are erased.

    Since you have a Ryzen cpu with unknown bios version date,before you start messing around with speed settings of any kind, goto the motherboard vendor website and download the latest version of bios and install it according to directions. Do so exactly, do not assume the pc is bunk and turn off power!

    This is Asus procedure. Follow exactly.

    Once the bios is flashed and current and the pc is back up and running stable, then start adjusting. Take the time to look up/Google OC and ram xmp procedures. Only adjust 1-2 settings at a time. Do not change settings by large amounts. This will take several reboots and waiting on stability.

    Before I touch anything, I wanted to ask is the battery very fragile? Can I just remove it with my hand? Which part of that battery should I touch and which part can't be touch?
  12. It's a battery. About the size of a quarter, but thicker. You'd have to stomp on it to damage it.

    There's a little catch on one edge, you push lightly on that and the battery will pop out. Return the same way it comes out.

    Before I remove the battery, I also remove the gpu in order to give me some room to move the cmos battery out, but then when I tried to screw the gpu back in, I realized my gpu wasn't screwed very tightly because the screw doesn't really fit the hole, is that ok or should I use a little bit of force to try to screw it as tightly as I can? I can sent a picture of that if you want.

    here's the picture. You can see that the screw is very loose and i know it's hard to see in this picture but there's a gap between the case and the gpu. Should i just leave it like that?

    Also reset cmos doesn't work
  16. The screws should align correctly. Loosen up the other screw, that'll allow the bracket to adjust. Then install the screw that currently wonky, correctly. Then screw both down. By forcing the screw, all you'd end up doing is either stripping out the threads on the screw or in the retainer plate, leaving you with a loose fitting. Just make sure the gpu is correctly seated first before screwing down permanently.
