More context is golden

Ok, it seems that you have a graphics card issue.

#

Here are some possible issues: A fault in the GPU: If the GPU is damaged, it can cause the white VGA light to appear, and you may need to replace it.
Incompatibility between components: If the graphics card is not compatible with other hardware components, it can trigger the white VGA light.
Poor connection to the PCIe slot: If the graphics card is not securely connected to the PCIe slot, it can cause the white VGA light to appear.
Dirty components: Dirt or debris on the graphics card or motherboard can interfere with the connection and cause the white VGA light to appear.
Not updating or incorrectly updating the BIOS: Updating the BIOS is important for communication between hardware and software. If not updated correctly, it can cause the white VGA light to appear.
CPU pin issue: Incorrectly installed or damaged pins on the CPU can trigger the white VGA light

I had a similar problem one time

#

What HDMI version is your new GPU?

#

What HDMI version is your cord?

#

And lastly, what HDMI version is your monitor?

#

If the answer is the same for all 3, then something is wrong with the monitor, most likely.

Well, you don’t have to use DisplayPort, but it is beneficial.

So yeah I ended up changing the port for the hdmi cable and that seemed to help I just plugged it straight into the gpu

#

Everything booted up like normal
