hello i have an asus rog g513qr ryzen 7 series 5000 that initial not powering on the cpu was damaged , after changing the CPU, bios was corupted and i write another, after we have image on display and windows i attached picture ,bios is damaged with bad serial u have picture (the ic grafic is nvidia 3070) do you think the grafic card fault is from bios or i have to solder the ic or replace the GPU IC?

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:
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.
If you get stuck or want a second opinion, feel free to hit us up. We do board-level repairs and BIOS/GPU work, and we’ve seen a bunch of these ROGs with similar issues. You can check out our shop if you want — happy to help out if you need it!

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.

MPS PMBUS PASSWORD PROTECTION
MPS PMBUS PASSWORD PROTECTION
Do processor circuit ICs (VRM) really have passwords?
Do you remember the video where I explained how to program modern processor circuit ICs using a PMBUS programmer? I mentioned at the time that in some cases, we would need the schematic, because even though there are many dump files available now, for some models it’s not possible to backup the file from another board because the ic is protected.
This is because some modern processor VRM ICs support a feature called PMBUS Protect. This feature allows the manufacturer to set a password to protect the IC. It provides three levels of protection:
As for the second type, you can still take a backup and write it to a new or used VRM IC later without any issues.
Are there any ways to break this protection? No.
Are there any workarounds to bypass it? No.

This is because some modern processor VRM ICs support a feature called PMBUS Protect. This feature allows the manufacturer to set a password to protect the IC. It provides three levels of protection:
- Protection from reading the registers
- Protection from writing to the registers
- Protection from both reading and writing to the registers
