Question Enabled Secure Boot and now PC no display

[Jeremy L]

So I needed to enable Secure boot, beacuse with Windows 11 Riot's Vanguard Anti-Cheat requires you to have it on in order to play Valorant. I did that and after I had saved and exited BIOS there was no display on any of my monitors after my PC restarted. Screen turns on for a few seconds displaying a "No signal" message and a count down from 5 seconds to powering off the monitor.

Specs:
GIGABYTE B550M-K
RYZEN 5 5600X
16GB RAM
GTX 1660 TI
Windows 11
Monitor is Samsung Odyssey G5 34" 165 Hz

I have tried everything I have found on Google including Reset CMOS, clear any residual power stored in the power supply after unplugging it, shorting the CLR_CMOS pins on the motherboard, trying to boot with 1 stick of ram and the other, no grapics card ( just to be sure, r5 5600x doesn't have integrated graphics so I expected no display) blindly going into bios and resetting using my memory from the layout, but I don't think it even reaches that point if there is no post. I have also tried to use a different SSD to be sure also a light version of Windows 10 on a USB Thumb Drive as a Boot Device, but still no Display, its more like the monitor doesn't recognize that there is any video output so it shuts down and also it seems USB devices don't work either as my Keyboard doesnt light up unless I press a key which happens when my PC is off, because its still receiving a bit of power if the power supply is on (obviously) only thing I can't do is updating BIOS since my motherboard doesnt have a flash feature and I cannot access bios so I have no way of updating it to see if that helps

PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Corsair 650 Watt 80 PLUS White Certified PSU about 4-5 years old gpu is 2019 cpu and motherboard i bought a month ago ram is 2019 i believe montior is 6 months old all in perfect condition as far as i can tell the system worked completely fine until yesterday when i enabled Secure Boot

If you disable Secure boot, does the monitor/display once again?

Even if you are unable to play games Valorant etc..

Objective simply to get back to a working state and then be able to check configurations and logs.

Not sure, full disclosure, about what may be happening - games, anti-cheat apps, and so forth often being problematic.

I am also going to move this thread from Systems to PC Gaming. More applicable thread and someone in the gaming community may recognize the problem and offer a solution.

I cannot disable the setting because i cannot access bios it doesnt boot
After noticing something weird i shut down every other noice in the room and listened closesly to the computer, it seems that when its on and the fans reach the normal speed it sounds like they stop and after they slow down a bit start up again

 

[Ralston18]

Which fan or fan(s): CPU, GPU, PSU, or case?

Likely that the fans slow or stop because the system is not really doing anything and there is little or no need for cooling.

Do you have access to a known working PSU (650 watts or more) that can be swapped in? Remember to use only the cables that come with the swapped in PSU.

They slow down and speed up again case fan and the cpu fan

I have a working 450 watt psu but all worked fine until yesterday i dont think the system uses even 400 watts tho

Edit
It also does the same thing with a different psu

They dont completely stop they slow down a bit and the speed up and it gives the same sound as if the pc is starting again

Wattage is important but what is also important is the PSU's ability to respond to changes in power demands.

Especially spikes; The PSU may be able to provide the wattage but not fast enough.

A 4-5 year old PSU is very likely at or nearing its' designed in EOL (End of Life) - all the more if there is a history of heavy gaming use or video editing.

And also remember that PSUs provide three different voltages (3.3, 5, and 12) to various system components. A failure on one voltage rail can and does result in problems while other components may seem to be "working".

Another possibility being a thermal shutdown. Has the thermal paste been reapplied?

Test with another PSU. 400 watts may be enough for a simple swap in test. Just to determine if the system will be able to boot once more.

I have used this computer for only a month so i dont believe that to be the reason the thermal paste is about 3 weeks old and with the other psu it did the same thing, also i tested ram and its still doing it, i uninstalled the gpu and still does it

Demonstration video
here is a link to a video i recorded where you can see the fan slowing down and speedin up again. I recommend to watch the entire video

 

[das_stig]

1st thing I would check is do you have motherboard speaker attached so you can here any error beep codes or onboard error LED it has one and look them up in the manual.

No it has no leds or speakers

Need to go back a bit then....

This motherboard:

https://download.gigabyte.com/FileL...e_1001.pdf?v=87bba5603e0f20b147063e0eea0c7e40

[Verify that I found the applicable manual.]

Read and review the entire manual then work through the manual to double check everything.

And indeed, check the speaker as suggested by @das_sting. Reference Page 18 = SPEAK. You will need to connect a speaker if a speaker is not present.

Overall, it can be expected that the CPU fan would be slowing down and speeding up again as shown in the 12 second video.

However, it may "cycling". Gets hot, fan speeds up, cools down fast, fan slows, gets hot again, fan speeds up --- loop repeated.

Check fan connections per Page 16.

Clear CMOS per the User Manual's instructions - Page 21. Install a new CMOS battery Page 20.

Just as a matter of elimination.

I have this motherboard
I have tried clearing cmos, i have no speaker in the motherboard and i would assume normal pc usb speakers wont work in this case

Also im not sure but this motherboard has some kind of smart fan stop feature as displayed on the website i linked. Could that be the reason its doing that?

Upon closer inspection i noticed that only the cpu fan was tuning down and up and sounds like the pc is restarting over and over
I'll get another video with sound included

 

[Jeremy L]

Here is a video where you can hear the sound i mean

You'll need either a different gpu with UEFI support or
cpu with integrated GPU.

I dont have any

Then you'll need to get it somehow.

Ryzen 3 3200G - for example has iGPU.
It requires BIOS version F3 though (for revision 1.0 board). If you have never done BIOS update, then BIOS is probably on version F1.
For revision 1.1 board 3200G is supported with initial FA BIOS version.

I already sent an email to the store i bought it from since im pretty sure they do repairs i asked if they could use one and disable that feature

 

[rustigsmed]

try changing the cable port and also if using DP (go with hdmi over DP).
