It sounds like your PC is experiencing sudden crashes that cut video and audio while the components keep running, which often points to either power delivery issues or storage/driver problems. Since everything is brand new, the power supply could be a culprit, especially if it’s underpowered or faulty. The slow loading after the crash hints at possible drive corruption or memory issues. I’d check event logs, run a memory test, and try stress-testing the PSU and storage to narrow it down before assuming a component is dead.
