Hardware 3.3 beep code issue

[Cianbtlr00]

I have a Z4 G4 workstation with a 1000W PSU, an Intel Core I9-7980XE, 64GB DDR4 RAM and an ASUS GEFORCE RTX 2080 Ti.

The maching and GPU are both only 5 months old and I have been having a problem with the machine while gaming. The GPU is seated properly and also has the required connection to the PSU. While I game the maching will make a very loud engine sound and shut down. At this stage I get a 3.3 led beep code and I can not find a solution anywhere. Everything is up to date including the BIOS, Drivers etc.

Not sure I can help but will offer a suggestion. You posted in the gaming section btw, but you have a business class PC which is a different section altogether.

I assume you added the graphics card yourself? The beep code for 3.3 is... The embedded controller has timed out waiting for BIOS to return from graphics initialization.

Did you try removing the cmos battery for 10 minutes with the machine unplugged and reset the bios?

One user had a similar issue and he had to go into the bios > Secure Boot Configuration and uncheck the box next to "Enable MS UEFI CA key."  May or may not be your issue but worth a look.

Does this happen before the GPU heats up from gaming? If the issue has been this way ever since you installed the GPU, another possibility is a faulty graphics card, but I dont know enough details about your PC.
