trying to figure out why, once again, my work pc (intel i9-9900) has freezing issues again (display stays on, sound stops, needs power cycle). before the freezing i get audio dropouts and cursor stuttering
@mntmn I ask because I've had three hardware issues that matched these symptoms, and each time the MCA/MCE logs generated by hardware were critical to tracking down the source.
first one was caused by PCIe ASPM; worked around by disabling ASPM, and fixed in a later BIOS.
second one was a bad DIMM with a very transient fault. ECC correction events told me which DIMM.
third case showed internal cache faults on one of the CPUs; the cause was motherboard failure.
On consumer boards, that might not work very well though, shabby firmware development causes MCA/MCE to not be reported properly on many, many boards.
(not to mention that you're not running ECC memory!)
Oh yes, I forgot a step: Run Memtest86+ for an hour, minimum! Ideally, keep the inside of the PC warm (50-60°C) with a space heater, etc.
@manawyrm@mntmn yeah I was tracking these issues down on a workstation with a dual Xeon board that cost £700 so I may have had an easier time of it than is typical with consumer boards.
@manawyrm@scy fun fact, you can drop pin headers into the outside edges of an isa slot and then push a couple of credit cards into the slot to push the pins outward to engage the headers.
