Hi,

Had anybody ever seen a BIOS return an unknown error before? Not sure what happened.

The attachment 20250111_074357.jpg is no longer available

The board was working. I swapped the GTX 285 GPU for a GTX 970 and it came up with this error.
Swapped the 285 GPU back and the issue remains. I tried putting an ATI X850 XT PE in, and the same issue. Tried a PCI Geforce 6200. Same issue.

The motherboard is a socket 771 with G41 chipset. A generic Chinese board rather than known brand.

The GTX 970 works fine in my Socket 775 PC.

I have tried removing the soundblaster live. No difference.

I have tried clearing the CMOS.

I have tried reducing from 2 to 1 ram modules. Tried both slots with different modules.

Any ideas?

Just tried removing the GPU and used the onboard VGA port. The machine seems to start up OK like that. Though I have no drivers in XP for this onboard graphics

Actually. Spoke too soon. It is doing it with onboard graphics now. No expansion cards currently installed. Has the mobo suddenly died do you think?

The reported CPU temperature seems suspiciously cold.....

Could CPU have an issue?

Try Reflashing the BIOS. Are you using the latest version? If you are, flash to the previous version.

It's an unknown brand motherboard. G41fB is the only thing I see that could be a model number. Are you suggesting that the BIOS got corrupted somehow? It was working OK. For months. It was my testbed for checking that purchased PCIe GPUs work....

Just realised my above response could be read as dismissive and ungrateful. It wasn't meant that way. The issue is that I don't know where I can get a BIOS from that's compatible with this board.

Also on the couple of occasions I've got into Windows after this message, the PC seems to completely lock up after a while. So I think flashing the BIOS would be a risky move given that it's unstable currently.

I'm thinking I may swap the CPU just in case there an issue with that. I can't explain why putting the GTX 970 seems to have broken it though. Maybe that's just a coincidence.

Do you happen to have one of these boards? With the info given, I think you have an Esonic board.
There are some BIOS files available.

It doesn't look like any of those with regards to layout. Who knows if the BIOS is compatible though...

Please excuse the dust. This test bench is in my garage, where I also cut wood for woodworking projects.

Are you able to export the BIOS and post it here?

Can you see if the screenshot is from an AMI (U)EFI or classic BIOS? Maybe surprisingly to some of you, I don't have any experience with (U)EFI and on my BIOS utility/tools page there are only classic BIOS tools hosted.

If it is a classic BIOS, the right tools to save the BIOS are AFUBSD 3.12 / AMI AFUDOS 4.40 / AMI AFULNX 4.27 / AMI AFUWIN 4.48 / AMI AFUWINx64 4.48.

Edit:
The screenshot from inside the BIOS (temp / rpm / voltage) speaks for classic BIOS.

kind regards
