As the title says, starting a few days ago my computer has started randomly restarting without warning. I checked the Event Viewer, and the error is always Event ID 41 - "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." Screenshot from EV: https://i.imgur.com/hlmmFEs.jpg.
From what I was able to find through google searches I've seen others with similar problems get told it might be the power supply failing, but I wanted to know if there's any way to confirm that's whats happening before trying to replace it. I know my computer in general does run hot, especially my video card which has caused me problems in the past (I am on a tight budget and trying not to replace it if possible, meaning that I've simply stopped playing anything that taxes the video card too heavily). That's been a problem for a few years now though, so I don't know why it would affect the PSU or anything else so suddenly. Screenshot of HWMonitor temps: https://i.imgur.com/yaJkFo2.jpg.
Would love any opinions on why this is happening and what I need to do to fix it. Thanks.
