Help needed, windows boots but no signal on display.

My PC Specs:

  • Motherboard: MSI B650 Gaming Plus WiFi

  • CPU: AMD Ryzen 7 7700

  • GPU: ASRock Intel Arc B580 Steel Legend 12GB (latest drivers installed, base settings)

  • Storage: Kingston NV2 SSD (only drive)

  • PSU: DeepCool PQ650M 650W

  • BIOS: EXPO Profile 2 enabled, no overclocking 

  • Display: LG FHD TV (1080p 60Hz)

  • OS: Windows 11 Pro, fully updated before issue

What happened:

This has now happened twice.
Two months ago, after moving things around at home, I swapped my HDMI 2.0 cable out for an older HDMI 1.4 (shorter one), and suddenly the PC would boot into BIOS fine but give no signal when entering Windows. Typing my PIN blindly didn’t work either. At the time, I just clean-installed Windows since the system was only a week old, and that solved the problem — even with HDMI cable changes afterward.

Now today, my HDMI 1.4 cable broke off in the TV's port while moving it, so I switched back to the 3m HDMI 2.0 cable. After that, the exact same issue returned: BIOS loads, but once Windows is supposed to start, no signal. Typing my PIN blindly didn’t trigger anything — no RGB profile loading either.

What I’ve tried so far (with help from AI):

  • Verified the HDMI 2.0 cable works on a different PC with the same TV.

  • Confirmed boot order and display output in BIOS are correct.

  • Entered Automatic Repair Mode → Ran Startup Repair.

    • After this, blindly typing my PIN now triggers my RGB fan profile — so Windows is at least partially booting, but no video.

  • Entered Safe Mode with internet acces (Option 5) → Hit the Microsoft PIN bug:

    • When I click “Set up new PIN,” the Microsoft login window opens and instantly closes.

  • Tried Safe Mode (Option 4) too — same result: asking for the PIN with no way to bypass or switch user.

  • Enabled hidden Administrator account via CMD in Recovery (net user Administrator /active:yes) — success.

  • Tried rebooting with shutdown /r /t 0 — command not recognized. Used wpeutil reboot instead.

    • Result: back to no signal after BIOS.

  • Booted back into safe mode, can't find the hidden Administrator account that I activated.  

  • Plugged in Ethernet to try Safe Mode networking — but no Wi-Fi options showed up, and it didn’t help.

At this point, I'm stuck in a loop — I can’t log in due to the PIN bug, and I can’t access Windows normally due to the no signal issue.

What I suspect (What AI told me could be the issue):

It seems like the Intel Arc GPU driver might be corrupted or isn't playing nice with the HDMI handshake after a cable swap. Possibly Windows is trying to use a display mode or output method that’s failing, leading to black/no signal after BIOS. I need to get into safe mode and get rid of the Intel Drivers to get video and boot into windows normally. Then reinstall everything and it should work properly.

What I need help with:

  1. How can I bypass or fix the PIN login bug so I can log into Safe Mode as Administrator?

  2. Once in Safe Mode, how do I uninstall or roll back the Intel Arc GPU driver? I want to reinstall it fresh after I regain access.

  3. How do I check the status or error logs of the Intel GPU driver to report this issue to Intel properly?

  4. What can I do to prevent this from happening again? Swapping HDMI cables shouldn’t break my PC’s ability to boot.

If anyone has run into similar problems with Intel Arc GPUs, HDMI handshakes, or the Microsoft PIN bug in Safe Mode, I’d really appreciate your input. I just want my PC working again.

If someone asks for additional info I'll do my best to provide it!

Thanks in advance for reading and helping out,
– Chris

...the issue is likely tied to a corrupted Intel Arc GPU driver or a bad HDMI handshake post-cable swap, causing the screen to go black after BIOS. The fact that Windows boots (your RGB profile loads) but shows no display points to a driver-level display mode failure. On the login screen in Safe Mode, try clicking “Sign-in Options” and selecting password login instead of PIN. If that doesn’t work, boot into Recovery > CMD and disable the PIN requirement via registry edits. Once logged in via Safe Mode, go to Device Manager > Display Adapters, right-click the Intel Arc GPU, and choose Uninstall Device (check "delete driver software" if available). Use Intel’s Driver & Support Assistant or the Download Center to install the latest WHQL driver. Choose a clean installation during setup.

quick question... Are you using Intel’s official driver or ASRock’s version?
