Question This is one dead MBO, right?

[vjekoslav]

Hello!

Im trying to confirm if the MBO is most likely culprit here. Sorry for a bit longer post

PC:

Ryzen 5800X
Corsair RMx 650W
1080Ti Aorus
4 x 8GB Crucial Balliatix (Micron-E), oc'd to 3733 mhz

MSI B550 Tomahawk

Would like to describe what's happening, cronologically. Hope this way I explain it well.

1. I was playing game of Hearthstone, pc froze. I didn't think much of it.

2. First reset at this point

3. All RGB LED's work, fans are spinning.

4. Post after 30 seconds longer delay than usual. Message on display: Over Current have been detected on your USB device. PC will shutdown in 15 seconds to protect your Motherboard.

5. Disconnected all USB devices, USB front panel as well. Restart. Same message. I checked each usb port with flaslight, no visible contacts or fragments.

6. Cleared CMOS, CPU light was red for 30 seconds. But it dissapeared, PC posted, managed to enter UEFI.

7. Restart. VGA light solid red now.

8. Reseated GPU. Took out RAM, left only one stick. No post. VGA light red. Tried each ddr stick solo, same thing.

9. Another CMOS Clear. PC boots with all sticks of RAM back in, enters Windows normally.

10. I was suspecting VGA, so I fired up Furmark. It passed, normal temps, everything was normal. 3D Mark worked fine as well.

11. At this point I thought all is fine, so I shutdown PC.

12. Turned on PC, Over Current message again.

13. Restart. CPU solid light red for 30 seconds, then it stopped. Righr after it ,VGA light turned solid red again.

14. Last thing I thought I might try was BIOS update. It froze at 5% for about an hour. There is image on both monitors, VGA seems to be working fine.

So, you think it's MBO actually? I have no way of testing gpu, ram or psu on another pc unfortunately

How old is that Corsair PSU? Heavy use for gaming, video editing , or even bit mining?

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all cards, connectors, RAM, and jumpers are fully and firmly in place.

What USB devices are connected?

If you have a multi-meter and know how to use it (or know someone who does) you can do some testing on the PSU.

Not a full test because the PSU is not under load. However, any voltages out of tolerance would make the PSU suspect.

I will definitely check out entire pc, deal with dust, potential bad connections, loose jumpers, anything really.

Also, multi meter - great idea. Will see if i can find someone.
Yeah, heavy use of everything you mentioned, minus mining

USB devices I usually had connected were logitech mx518, hyperx gaming KB and usb headset. Coincidentally, when the PC froze for the first time, I had Samsung A52 plugged in and used it for USB tethering.

I got over current messages with all the USB devices unplugged as well.

PSU was bought together with Zen 1 and 1080ti, when they got released (so, March 2017 if I recall correctly).

I should perhaps look into PSU as you suggested. I wonder if 10 year warranty from corsair could do a trick here?

PS. I am now not sure if I will manage to reset BIOS, considering this state of MBO and/or PSU. BIOS update is still sitting at 5%. I have to reset BIOS, but might brick the board if psu fails...
