Loud beep from my PC (not sure where) when doing graphics intensive work

[Imp]

Motherboard: ASUS ROG Strix Z790-A wifi

GPU: ASUS NVIDIA GeForce RTX 3070Ti

In my new Win 11 build I used a new motherboard (above) and a GPU from my previous build. The GPU worked fine on my previous ASUS Prime motherboard so I'm assuming it's not the problem. 

When I'm using a graphics intensive application, I get a beep of varying length. The application works fine. The beep returns now and again. My case is large with good airflow. 

Does anyone have any ideas  what the cause might be?

Thank you for any suggestions.

Hi @Imp 

When you say varying length, is it one long beep and then three short? As this indicates a VGA issue.

It's not a beep code. Sometimes the beep lasts a second, another time it may go for 3-4 seconds. There may be no further beeps for 5 minutes or over an hour. If I don't do anything graphics intensive (i.e. a spreadsheet or google search) there are no beeps.

Thank you for your help.

What are the CPU/GPU temps when the beeping occurs? Use HWINFO to see if either are thermal throttling.

Have not used HWINFO before. Will respond when I get information.

Thank you

I've done a little reading and installed HWINFO. Although the beeping events only happens when I use a graphics intensive application, it is very unpredictable. I've had hours in which the event never occurred. Also, when it does occur, I've experienced hours of no recurrence afterwards.

Would it make sense to run WWINFO in the background at all times and then look at the data after the event occurs and compare it to the preceding time-frame?

First of all, Thank you for bringing HWINFO to my attention , Silent_Scone. I had not been aware of it and it directly pointed at my problem. My CPU temperature peaked at 96 degrees when I heard the beep. I haven't solved my issue as yet, but have no doubt that either my thermal paste is not adequate and/or I need a more powerful CPU cooler. I had no idea that an i9 runs so much hotter than my previous i7 chip and therefore did not upgrade my old cooler.

Thank you very much for asking the right questions!!!

No problem. Check mounting pressure and ensure contact is good. What cooler and thermal application are you using?

You may want to consider a contact frame such as the Thermal Grizzly if you continue to have inconsistent temps.
