For a test run.

Try it with the case cover off and a house fan pointed at the PC.

If it does not crash or takes longer to crash that's a sign it's hardware.

If it's the same then you ask the PC's maker for what drivers to install in what order. Also ask if the firmware on all cards that have such is up to date. The repeating sound loop is a sign for me to ask the maker about drivers.
