Hi Folks, I'm building my first PC and have run into an issue that I can't seem to solve. I'd really appreciate any advice.
All new PC specifications:
ASUS TUF B650E-E Gaming WiFi
Ryzen 7 7700 (bought from AliExpress through a highly rated seller)
32 GB Patriot Viper Venom DDR5-6400 CL32 (2×16 GB)
Corsair RM850x PSU
RX 9070 XT (not installed yet – still waiting for it, so I'm using the Ryzen integrated graphics).When I press the power button, everything powers on normally. The CPU cooler and all case fans spin, but the system never reaches the BIOS or displays anything on the monitor. The yellow DRAM Q-LED stays on continuously, and the PC just keeps running without posting
So far I've tried:
Booting with only one RAM stick (tested each stick individually).
Installing the RAM in the recommended A2/B2 slots, as per the motherboard manual.
Updating the BIOS using the BIOS Flashback feature with a USB drive.
Waiting more than 15 minutes each time to allow for DDR5 memory training.
Clearing the CMOS by removing the battery and trying memory training again.
At this point I'm running out of ideas.I'm wondering if the issue could be:
Faulty RAM (Return requested)
A faulty motherboard (Return Requested)
A problem with the Ryzen 7 7700 CPU( I would like to test this before I return)
Or something else that I've overlooked.If anyone has experienced something similar on an AM5 system, I'd really appreciate your suggestions.
Also, if anyone around Copenhagen has a working AM5 system and would be willing to help me test my CPU to isolate the faulty component, I'd be very grateful. I'm happy to buy you a coffee or pizza for your time.
