PC fails to reach BIOS following Windows Update.
PC fails to reach BIOS following Windows Update.
Hello everybody!!
I have a problem with my PC. It was working flawlessly and yesterday Windows requested to install a couple updates, so I did. It then restarted and looked nice so I turned it off and went to sleep. Today it's not even reaching BIOS, just a black screen.
I've tried using the CMDOS jumper and moving the memory sticks around. I managed reach Windows once but then I restarted and without changing anything it was back to black screen.
My MOBO has a yellow led which according to the manufacturer indicates Memory issue.. If I put a RAM stick in the 3rd slot (which is usually empty), a red led also turns on, which indicates faulty CPU. Also, sometimes the fans will work, sometimes they will just move a bit, like tiny pushes.
Seems to be completely random. I've tried with and wihtouth GPU and with 2 RAM sticks and then only one of them (tried both separately in different slots)... and no results.
My system is:
CPU:
Ryzen 9600x
MOBO:
Asrock B850 Steel Legend Wifi
RAM:
16x2 GB Corsair (can't find the exact model but they were compatible with AMD)
Storage:
2x 1Tb SSD NVe Crucial (again, not sure about the model since they're kind of old; I checked a few days ago and were not affected by the murderous WIndows Update).
PSU:
EVGA G2 Supernova Gold 750W.
OS :
Windows 11 PRO, it was up to date with patches and any kind of updates till recently.
GPU:
AMD RX 6700
I don't have any other RAM sticks or CPU that I can use to check, and this seems too random for me. Any guidance would be welcome, thanks.
I made the BIOS update about three months ago. Because it won’t post to BISO at the moment, I can’t get the exact time, but it’s probably the last or second last one.
My PSU is a bit outdated; I bought it in 2015, which is roughly ten years, though it might be a little more or less. I just checked and found that its warranty ended in July, since it came with an extended 10-year coverage.
Your motherboard includes a BIOS FlashBack feature; refer to this tutorial for guidance. Watch the video at the provided link to explore whether updating the BIOS can restore your system. For your power supply unit, this could be an opportune moment to obtain a dependable PSU—borrow or rent one if possible, and consider replacing it once the problem is resolved.
Hello Lutfij!
I just updated the BIOS using that method, but the outcome remains unchanged. I suspect I still have my old CPU/Mobo in place—it's an Intel 8700 with its motherboard and RAM.
I might as well attempt to power it on to check what happens. I wouldn't expect the PSU to be the issue, since I played games yesterday without any problems and haven't experienced crashes or shutdowns before. The only time things went wrong was after a Windows update.
All in all, it seems like the problem might lie with the motherboard or CPU itself.
Edit:
I also tried connecting my old I7 8700 with DDR4 and SSD, which worked perfectly. That suggests we can eliminate the PSU. Using different SSDs also resolved the issue.
So it could be either the motherboard or the CPU. Am I correct?
