UCyborg Posted December 11, 2021 Share Posted December 11, 2021 (edited) Few days ago when I turned on PC, it took 3 extra seconds to start POST then BIOS showed only half of RAM (2 GB out of usual 4 GB). I rebooted it, still took extra 3 seconds, but remaining RAM returned. It seemed to work as usual otherwise, I said I'll worry about it next day. It occurred to me the next day it must have been 3 years since I've blown the dust out and didn't get around to it this summer despite the intentions. Took it to garage where the family has a small and noisy air compressor, opened the case and started blowing the dust out. Quite a bit of it accumulated in many corners and the amount of dust that came out of the CPU cooler (the silver part) was a bit shocking. Thought I had it all and it still came out on the second sweep. The CPU cooler is a bit massive, it's an Akasa AK-968. Combined with Aerocool V-Touch Pro case with big 400 mm fan, dust has an easier time getting in, so really shouldn't forget about it the next time around. Graphics card remained the cleanest. When I put it back together, the POST started when it was supposed to. BIOS was reset since I removed depleted CMOS battery a while ago and didn't bother getting a new one, so set everything back like it was before. Yesterday, I checked if jack sensing works by any chance now since it hasn't since last year, at least when it comes to standard green 3,5 mm jack for speakers/headphones at the back, so had to use software workaround to get the sound since the system thought there isn't anything plugged in. I restored EnableDynamicDevices registry setting in Windows to default, disabled and re-enabled device in Device Manager (the High Definition Audio Controller under System devices) and the sound still works. Also normally get the Not plugged in status if I unplug the headphones. So obviously don't need the equivalent setting on Linux anymore neither. All is well in the end. So thought I'd open a thread about it for others' to post their (dusty) experiences here. Edited December 11, 2021 by UCyborg Link to comment Share on other sites More sharing options...
