Dell latitude 7410 GPU issue

[vidvansh]

I was trying to install windows on this laptop and it just stops in middle and the screen looks like this. I thought it could be an BIOS issues so i tried installing updated BIOS on it but every time it just goes like this.
I don't know what are the options i have to fix this.
I am new to all this. I have bought CH314a but don't know what to do next with it.

Looks to me like a bad GPU core — could be faulty RAM, but the GPU core is more likely.

If the system has a dedicated GPU, try running MODs/MATs, or Tserver/dmgg.py.

• If a bad RAM chip is detected, replace it.
• If the issue persists after replacement, you may have installed a faulty RAM module, soldered it improperly, or the GPU core itself is bad.
• If no bad RAM is found at all, then the GPU core is faulty.

If there's a dedicated GPU, you can disable it as a workaround.
If there's no dedicated GPU (i.e., it's integrated), then unfortunately, the only solution is to replace the CPU/integrated - chipset and GPU.

You could also try heating the GPU to around 180°C to see if it temporarily resolves the issue.
If it does, then the GPU is definitely faulty — but it might work again for a short time.

The fix could last just a few minutes, hours, days, or even years — you never know.
