The PC fails to connect to BIOS.
The PC fails to connect to BIOS.
I assembled my friend's PC and everything functioned perfectly. I installed Windows, applied updates, and everything seemed normal. Then I handed it over to him, who set up the drivers for lighting controls. After some time, he reported that after a few seconds to a few minutes the system would freeze, shut down, and restart into Windows. When I visited a day later, it wouldn’t boot into Windows or BIOS at all. The DRAM LED was lit but nothing else appeared, not even the keyboard lights.
I’ve tried several steps so far: booting with just one RAM stick, removing the GPU, updating the BIOS via the back panel using a USB, clearing CMOS three times (twice by disconnecting the battery, once by removing the battery), testing with only one RAM stick in all four slots, and attempting to use just an SSD. In every case, nothing worked. The yellow light suggested DRAM issues, the red light hinted at CPU problems, and sometimes no lights at all—though I see fans spinning when everything lights up.
PC Specifications: Case – Basic Light; CPU – AMD Ryzen 9 7900X; Mainboard – Asus ROG Strix B-650-A; Wi-Fi – Pure Power 12M 850W ATX 3.1 AIO; GPU – Intel Arc A770 NVME; NVMe Drive – Samsung 990 Pro 2 TB
Is there anything I can help with? Or is this a faulty CPU or motherboard? I’m just confused because everything worked until the programs and drivers were installed. Please let me know if you need more details.
Best regards, KLENNEX
Edit 1: CPU and GPU temperatures were normal. Checked them: CPU ranged 40-50°C. Updated July 9, 2025 by Klennex
You need to understand the situation better. Everything seemed normal before, but now it's malfunctioning unexpectedly. If you reinstall the device using the updated motherboard, you should only check for issues that might arise during setup, not necessarily install new drivers or BIOS unless you notice specific problems.
That’s how things usually go—something fails, but it’s okay. At least you had a chance to use it. It’s not a problem outside the warranty, so no need to install the BIOS unless there’s a specific reason. The drivers are stored on the drives, not the motherboard.
Thank you very much! I’ll place an order or return the defective item.
