No signal after normal operation for a week

Hi, I just built my first custom PC last week and it has been working perfectly for a week. However, yesterday I tried to enable secure boot and had to disable CSM in the process. after I saved and exited the bios, the display went straight to no signal. I have already tried troubleshooting some things such as:

Clearing CMOS by shorting the CLR CMOS jumper as well as removing the CMOS battery for about 5 minutes. I also tried resetting the gpu and ram, as well as using a display port cable instead of the HDMI one I normally used.

When I turn my PC on it turns on all my fans and RGB components including ram, but my monitor says no signal (the cable is plugged into the GPU) The motherboard doesn’t have any diagnostic LEDs that light up and the gpu fans start and stop spinning repeatedly (I assume the gpu does this to test the fans when booting but not sure)

My pc specs are:

Motherboard - Gigabyte B550 aorus elite ax v2

Gpu- powercolour fighter AMD rx 6700 xt

Ram - Corsair RGB vengeance pro sl (16gb 3200mhz)

Case - Lian li lancool 2 mesh

CPU - AMD Ryzen 5600x

AIO - Lian li gallahad 240

PSU - Gigabyte 650w

Any help would be appreciated.

Secure Boot Enabling with Existing Windows 10 Installation

 If Windows was installed in UEFI mode (if your OS disk uses GPT rather than MBR then it is already in UEFI mode), then you can just enable Secure Boot in the UEFI/BIOS.

 Now Master Boot Record (MBR) disks use the standard BIOS partition table. GUID Partition Table (GPT) disks use Unified Extensible Firmware Interface (UEFI).

 But in your case your system drive was probably set up with MBR.

You will need to switch it to GPT.  Microsoft has a conversion utility called MBR2GPT that converts the disk to GPT and creates the necessary additional partitions.  You can run it from a Windows PE flash drive. The link below explains in more detail. Once done the Secure Boot on and CSM off settings in the UEFI/BIOS should now work.

Hi,

Sorry if my question was unclear, but the problem I am having is the pc not outputting any display signal after I enabled secure boot and disabled CSM. However, When I installed windows 11 I used a flash drive set as MBR to boot from. Not sure if this might be the cause of the issue.

Hi @Angad Baweja

If you system worked before you turned off "CSM" and you turned on "Secure Boot" then you installed in legacy mode or CSM.

You should be able to get into the BIOS regardless of what the hard drive is installed with. Hold down <Delete> right after turning power on.

<F12> will get you into boot menu if you are trying to boot a Windows PE flash drive.

I tried that but I am not able to get the PC to output any signal to the monitor, and hence not able to re-enter the bios

Hi,

Seems as though the PC is not passing POST. (Power On Self Test)

Try connecting a system speaker (supplier example only) to the motherboard header pins and check what the beep error code is. (see image below)

Here's the manual for the motherboard. The system speaker connects to the F_PANEL (Front Panel Header) see p.18 for where to connect the speaker and p.13 (#11) for where it is located on the motherboard.

Thanks, I’ll try this when I get my hands on speakers that can connect to the f_panel header. In the meanwhile, could I use a usb speaker with the rear io to listen for the beeps?

tarafından

@Angad Baweja

No the beeps are only applied to the F Panel header pins and nowhere else on the board.

FYI This is the same on every PC board not just your make and model.

The only difference would be what the beep code meant and this depends on the type of BIOS installed e.g. AMI, Award, Phoenix etc on the board by the board manufacturer.

As you can see in the image I posted, Gigabyte uses two different BIOS types in their product range depending on which board it is installed in

tarafından

Hey,

I tried this but I got no beeps.

Not sure if this means everything is ok or there is a problem

(I made sure the positive side was in the positive side of the motherboard etc.)

Could you help if you have any knowledge about this?

tarafından

@Angad Baweja

If it passed POST OK there should be at least 1 short beep.

From the description in your question above it sounds like it is trying to start but can't.

Try removing the ram and starting it again and check if you get an error code, perhaps 3 beeps or 1 short - 1 long beep repeated (depends on BIOS version)

Try the paperclip test on the PSU and make sure all the voltages are there and correct.

If there are no beeps with the ram removed (also try the GPU card removed as this should also produce a beep code) and the PSU voltages are OK, then there's a motherboard problem.

It it were AMI BIOS and the CPU was faulty then you should have gotten 5 beeps but since there are no beeps its the motherboard.

Check the warranty on the board as it shouldn't have failed this early and get it replaced. Sometimes it can happen though.

Thanks for the help, I’ll try to do it later today

Hopefully it works :)

If the monitor went blank when you enabled Secure Boot and disabled CSM, then Secure Boot may have disabled your monitor or graphics drivers. Chances are, Secure Boot doesn't recognized the drivers as digitally signed. Your options may be to:

  1. Disable Secure Boot again.
  2. Reinstall the OS under the current configuration (with Secure Boot enabled).

Hi,

Since I cannot access the BIOS as there is no signal to the monitor, Should I reinstall windows 11 to fix the problem? Not sure how this would help disable secure boot but I have never done troubleshooting before so I’m not sure if I should try it or just wait for the front panel speaker to see what error code it gives me.

Thanks for the help

You should be able to enter BIOS with a display and no OS (or even a HDD/SSD installed) as the BIOS chipset loads basic vga video drivers on startup.

This is of course if the motherboard passes POST which would include having a working video adapter, either a GPU card or integrated CPU graphics (which your CPU doesn't have) or working ram etc.

tarafından

@Angad Baweja Give it a try. You should be able to toggle Secure Boot on/off in the BIOS. If it doesn't work, then it will offer more clues as to what's wrong.

tarafından

I tried getting into the bios but my monitor doesn’t recognize any signal from the pc. It just cycles through the ports and says “no signal” and therefore I am not able to change the secure boot setting back to off

(The gigabyte logo doesn’t even show up, just a black screen with no signal on it)

Try the following:

1. Reseat the GPU in its slot or insert it into another slot. Clean the contacts on the GPU.

2. Remove the GPU completely and try to boot again.

3. Connect the GPU's power cable to a different port on the power supply, if possible. The fans starting/stopping may be a red flag.
