Hi, I'm guessing as a new member I need to state my problem here and can't post a new thread directly, right? MOBO: AsRock B650 Steel Legend WiFi. Well...There's an issue I need to troubleshoot. I've built my computer a year ago, AMD based. And it was working fine (though sucked in terms of graphics issues since windows 25H2 retarded update). A few days ago it fired up nicely, I played a bit, done some web browsing and left it for like an hour. It went to sleep mode (did not switch off the components, just the screen) and it never recovered from that. I couldn't get it to switch the screen on, I forced a restart and since then (or even before the restart, I didn't catch this) the CPU POST diode is always on (red). All of the components and peripherals except for the screen come alive when I switch the computer on. All the RGB components work. However the screen doesn't show anything even for a split second. I hooked up a laptop to the screen - the screen works. I hooked up a speaker to the motherboard, started the PC without any RAM so far - not a single beep (I checked the speaker and it works alright). I tried just 1 RAM stick as well and this doesn't help. I checked all the power cords, especially CPU ones and they sit tight on both ends. I reset CMOS twice according to the quick start guide which came with the MOBO. I'm about to take the CPU out, examine pins and stick it back in. I don't have any spare, compatible CPU, MOBO, GPU or RAM to test by replacement. Is there anything else I can do to find the offending component or do I need to RMA the CPU straight ahead or pay for troubleshooting at some local shop?

Try doing this: https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal" rel="nofollow - https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal Make sure to leave the system fully disconnected from power for about an hour. Sometimes a failed sleep state can cause the system to fail to POST, typically following the linked steps will resolve the issue if it is not a dead/dying CPU. If this fails then I would have a local shop look at it for you, it may save you time, effort and money if they can at least determine what the fault is caused by. Good luck. -------------

Hi, Thanks for the tips but I got the message after I've given my computer to a local shop to run a check on it. Turns out my AsRock motherboard died :( I need to RMA it. The tricky question I'm left with now is - is my CPU alright? Cause the technitian checked all components except for the CPU with the rationale that putting it into his own mobo runs a risk of shorting and killing it so he's hesitant about it. Is there any other method? I don't really think so...and I believe I'm risking a life of a new mobo in case CPU got a hit, am I not? |

I would initiate an RMA on the CPU too, that way they will test it and return it if it's fine or replace it if not. With issues like this it's typically best to RMA all the suspect components. -------------

Good luck and let us know how it goes when you get the replacements  -------------

Allright...both are dead. CPU was replaced by one distributor, MOBO was refunded by another distributor. Now the question is...do I stick with AM5 platform? :( The MOBO look amazing on paper, next one with similar hardware costs twice as much. Another question is - is this really the AsRock issue? Cause I'm bombarded with news about AsRock MOBOs specifically having issues on AM5 platform. What's up with that? |

No one knows for sure and none of the manufacturers are talking. Personally, that makes me suspect AMD. If all the other brands were wagging fingers at ASRock or another brand that would be different but they are keeping quiet too. Blame aside, ASRock did release this statement a few days back, along with BIOS updates intended to address concerns: https://www.asrock.com.tw/news/index.asp?iD=5744" rel="nofollow - https://www.asrock.com.tw/news/index.asp?iD=5744 In spite of all the publicity and attention being drawn to this issue it is still an exceedingly rare occurrence. To put it in perspective, there were more dead CPUs caused by intel's mess up with 13th and 14th gen microcode. These things happen. It's better for it to be a known issue that is receiving support and RMAs than for it to be completely isolated and potentially fall outside warranty etc. As to sticking with the platform, that is entirely up to you. Personally, I would see how it goes with the replacements and the new BIOS updates. If something goes sideways again then swap out the 9000 series with a 7000 series CPU and be done with it. As in, get the replacement CPU (RMA) then sell it and pick up a 7000 series equivalent. In all likelihood your system will be fine now. It would seem AMD has been working with all it's board partners to get the the bottom of this issue. Bare in mind, all AM5 boards available gave no issue with 7000 series CPUs. As for this being an ASRock issue, no, it isn't limited to ASRock, other manufacturers are experiencing failures too, it wouldn't surprise me if they all were. The reason ASRock has gotten more attention is because more users reported burned CPUs on an easily accessible redit group. Reports of similar issues from other brands were not so neatly collected in one place. I believe there have been more reports of failed CPUs on ASRock boards, I am not trying to say otherwise, but not by anywhere near the margins the media is trying to claim. To put your mind at ease, even if you run into problems again, they will be addressed again. I doubt that will be the case however, you should be fine with the new updates. Just sit back, enjoy your build and keep an eye on the ASRock news page for updates etc. -------------

Thank you for exhaustive reply! Actually my MOBO died with Ryzen 7 7600 CPU on, not 9000 series. I'll take a look at MOBOs this weekend and pick something. B650 Steel Legend WiFi is still tempting to try again, that is if I find one on the market. |

Your case is unusual. 1) Both the motherboard & the CPU died. Normally, the motherboard isn't killed, unless there is a physical burn type failure. 2) The motherboard failed with just the CPU diagnostic light. The more common is with both the CPU and the DRAM diagnostic lights. 3) You had a non-X3D 7000-series CPU. One question, though. How did the local technician confirm that the motherboard was dead? If he was afraid to test the CPU in another motherboard, in the fear that it could damage a perfectly good motherboard, he wouldn't have put a perfectly good CPU onto the motherboard to test it. But regardless, assuming all three of the above assumptions are true, then I would highly recommend you replace the power supply. Other than lightning / electrical surge type events, the most common cause of motherboard+CPU failure is the power supply. At minimum, tell us what brand/model of power supply you have, along with other components in the build. I'm just curious if the power supply was running near its limits or not. |

Excellent catch eccential. I had assumed we were dealing with a 9k series CPU, it being a 7600 changes everything. As eccential said, you will want to replace that PSU to be safe. 999 times out of 1000 a dead CPU and board is caused by a bad PSU. -------------

Hi, The full list of components is at the bottom of my OP. The technician spent an ample amount of time diagnosing everything in the PC. He did insert one of his spare CPUs into the MOBO as well, was reluctant to do it the other way round (it's a small shop, though with houndreds of amazing reviews). He mentioned that there have been lots of people coming in with dead AM5 CPUs in recent months. I've decided to go with B850 tomahawk max wifi this time, due to pretty much the same price and amazing reviews. The PSU seems pretty good, though there's always a chance...Mind that the computer was not under stress when it happened. Can I even RMA the PSU only on the basis of both components simultaneous failure? |

| In case it slipped under the radar - all of the other components work and have been working all the time - fans, GPU, RAM - all of those turn on and give out the RGB / spin even when plugged to the dead MOBO. The only other component that does not launch is the screen (works, just not with the broken MOBO). |

Yeah, I don't see any red flags. Chalk one up for bad luck, I guess. |
