The PC isn't showing output to the monitor and isn't communicating with the BIOS.
I recently assembled a new setup using some reused parts such as fans, drives, and power supplies. The components include a CPU: Ryzen 5 7500F, a CPU cooler: Thermalright Assassin X R SE ARGB, a motherboard: ASRock B650M Pro RS with BIOS version 3.50, RAM: Teamgroup T-Force Vulcan 16GB at 6000 MHz DDR5, storage options: Crucial P2 500GB (boot drive), Kingston A400 240GB, and WD Blue HDD 1TB 7200rpm, an ASRock Arc B580 Challenger GPU, a PSU: Xigmatek Hydra M 550W. This build is about 4-5 years old but has been unused for roughly one year. The chassis is MIK Barbatos M, the operating system is Windows 11 22H2, and the monitor is a Philips 24M2N3200NF. It functioned properly on the first day, yet it started to bluescreen (VIDEO_TDR_FAILURE). DDU might have addressed it, but I’m unsure because I also encountered a new problem where the system wouldn’t output to the monitor or even the BIOS. I managed to boot it off briefly and it shut down quickly, but after a reboot it would freeze and restart immediately.
Other attempts I made:
- Changed display cables and monitors (all worked when connected to other devices)
- Updated or flashed the BIOS
- Replaced RAM in a different slot
- Reset CMOS
- Reinstalled GPU
- Sent the GPU for RMA, which said it was fine
- Followed a suggestion to wait a few seconds after powering on before turning on the monitor
None of these steps resolved the issue.
Additional observations:
- I’m currently using HDMI and have never used DisplayPort, though I’m open to testing it if it helps
- Diagnostic LEDs show no faults
- Before the problems started, I upgraded Windows 11 to 24H2 (it was 22H2 since the drive hasn’t been used much), but that caused a black screen with just a cursor; I could still access the task manager from there. I reverted that change.
Any advice would be greatly appreciated.

When sharing a troubleshooting thread, it's standard to provide full system specifications. Please list your build details as follows:

Include the PSU age along with its make and model. Also, mention the current BIOS version for your motherboard.
Quick update
: I brought the PC to get checked, and it outputted immediately once another GPU was plugged in. It's starting to make me think that it's some sort of BIOS/VBIOS shenanigans.
However, I tried rolling back the motherboard BIOS to the out-of-box version and it didn't seem to work still. Maybe the driver update (and the VBIOS update that might have come with it) may have played havoc with compatibility?
Final update: it was the PSU. I don’t really understand why, since 550W should be enough, but switching it out seems to have worked. Thanks for the advice still.
There are additional factors to think about beyond just wattage when picking a good PSU.
