Hey everyone, I'm having a major issue with my new PC build. After a few days of normal use, my monitor suddenly lost signal, and now it just displays a "No Signal" message on both my AOC monitor and a Sony TV. So I know it's not a problem with the displays. Here are my specs: I'm running an AMD Ryzen 7 7700 CPU with a Gigabyte Radeon RX 9060 XT Gaming OC for the GPU. I've got an Asus B650E MAX GAMING WIFI motherboard, 32GB of Kingston FURY Beast RGB DDR5 RAM (6000MHz), a Corsair RM850e PSU, a Kingston NV3 2TB SSD, and a Cooler Master Hyper 212 ARGB cooler.
The issue is that my monitor goes directly to "No Signal" and then to sleep mode, so I can't access the BIOS or anything. So far, I have:
- Swapped HDMI/DP cables.
- Tested on another Sony TV (got the same No Signal).
- Reseated the GPU and checked all the power connections.
- Unplugged and reconnected the RAM sticks.
- Reset the CMOS by removing the battery for a bit.
- Tried a power drain (held the power button for 30 seconds while unplugged).
- Connected to both the GPU ports and integrated motherboard ports (with the GPU removed).
- Updated to the latest BIOS version using BIOS Flashback.
The fans are running, and the RGB lights up, but I can't get anything on the display. Since it's an AM5 motherboard, I know DDR5 can sometimes take a while on boot, but I've let it sit multiple times with no luck. Any suggestions on what else I could check?

Have you tried using the integrated graphics on your CPU? Most AM5 CPUs have that feature. Just plug the cable directly into the motherboard's HDMI or DisplayPort to see if that works.
Check if there are any diagnostic LEDs or a Q-code display on your motherboard. These can give you insight into what might be wrong. The information for Q-codes is in the motherboard manual. Let’s see what those lights indicate when you start up your PC!
For the diagnostic, it seems like you're looking at the manual for the wrong model. Try focusing on the Q-LED Core feature on your board. If the power button stays solid, that usually suggests there’s no issue, but it’s worth double-checking.
