Tangentially related: I thought my 3 1/2-year old desktop computer (Bought in summer 2022, previous one lasted nearly 10 years and only died because the power supply burned up because I'd let the fan get completely clogged with dust) was shitting the bed. Starting about two months ago it would randomly freeze, regardless of what I was doing (even just reading a site like this forum, as the only tab in Firefox and no other programs open). It would either reboot without warning, or just abruptly go completely unresponsive to mouse and keyboard inputs and require a hard reboot. Sometimes it would go an hour or two, other times (and this was seemingly becoming more and more frequent) it would do it every five-ten minutes.
I opened up the case and vacuumed out the fans (they were somewhat dusty, but far from clogged), ran the hardware diagnostics and everything came back good, installed all the BIOS and driver updates that were available. None of it made any difference and as a last resort before taking it to a repair shop, I went out and bought a $130 UPS/battery backup at Best Buy to plug it (and the monitor, and my external HDDs, etc) into.
Lo and behold, we're coming up on 48 hours of up time since I did this after work on Friday, and NO ABRUPT FREEZES/REBOOTS!
