Hey man, sounds like you’ve been through quite a bit already with that G513QR — nice job getting it to boot up again after the CPU and BIOS issues, that’s half the battle.
Now, about the GPU — if the system is giving you a display and even loading into Windows, the RTX 3070 chip is at least somewhat functional, so that’s good news. A corrupted BIOS (especially with missing or wrong serial info)
can definitely mess with things like power delivery, thermal control, and sometimes how the GPU is initialized or recognized by the system.
Here’s what I’d check:
- BIOS version: Make sure you’ve flashed the exact right BIOS version for your laptop model — even a small mismatch can lead to weird GPU behavior or instability.
- Missing DMI info: If the serial number, UUID, or model name is blank or wrong in the BIOS, it can actually cause problems with how the system handles GPU and other components. You’ll want to reprogram the BIOS and restore the original DMI data if possible.
- Check the GPU status in Windows: Open Device Manager or use GPU-Z and see if the 3070 is showing up properly. If you see error codes, or it’s not being utilized at all, there might be something off with the vBIOS.
- vBIOS flash (with caution): If it’s a vBIOS issue, tools like NVFlash can help — just be super careful here. Only flash if you’re 100% sure it’s the right version and always make a backup first.
If you’ve gone through all this and it still doesn’t behave right — especially if you see artifacts, flickering, or no acceleration — then yeah, the GPU IC itself might be damaged. Could be a reball or full replacement job.
