Wow, it looks like my desktop is back from the dead! It’s a Halloween zombie miracle!
If you’re just joining us, last night my computer gave me quite the fright when it refused to turn on (no power to the keyboard, nothing on the screen, not even POST error beeps) — it looked like I had a dead motherboard. At the moment cashflow is a bit tight, and I also don’t have time to try a million fixes, and I need my computer working well so I can work from home, so there was no clear choice on whether to try to replace the motherboard/other components and rebuild the system (or a new system from parts, minimizing cost but maximizing effort), or to just order a new PC (which would cost more).
As I was searching for information on which motherboards could replace this one (a Dell XPS 8500), I came across a forum post about troubleshooting motherboard issues on this system. One poster (thank you anonymous poster whose link I lost!) suggested the most insane possible fix, which I will repeat here both for how unbelievable it is that this should actually fix things, and in case others have similar issues in the future and come across this post in their search: unplug the computer. Press and hold the power button. Pull the CMOS battery (a little CR2032 coin battery on the motherboard, just above the graphics card). Plug the computer in, attempt to start it. Unplug the computer. Press and hold the power button. Put in a new CMOS battery. Plug in the computer and attempt to start it.
I have no idea what in the CMOS/BIOS could have been so badly broken that it wouldn’t even return an error, but I’m so glad that random internet post saved me from buying a new computer (or a new motherboard and all the time needed to unmount and remount all the components).
It reset my BIOS settings (which took some attempts to get back to make all the other stuff work) and threw some weird errors, but hey, I am back online now! Weirdest damned fix I’ve ever done (but not quite to the level of “more magic“).
I still have one super weird and unsettling symptom: my computer doesn’t boot up right away when I press power. The lights come on, the fans spin up for about 5 seconds… then the lights go off, the fans turn off… then the fans spin up again and the monitors and peripherals come on and it boots. No idea why it has a false start there, but I’m just grateful it’s up and running now.
Speaking of random fixes, here’s another recent one that might make more sense:
I keep my phone in my pocket. That means it will pick up lint, including in the headphone jack.
My headphones haven’t been working lately, and it’s been very frustrating. They weren’t working at all with my phone, and occasionally would cut out on my computer. So I got new headphones. They work fine on my computer, but still cut out on my phone, and that just kept getting worse, until three weeks ago they wouldn’t work at all. I tried jamming them in as hard as I could, and they’d work for a minute or so.
Finally a tip on the internet said to clean out the lint. So I have the little floss pick things in my desk here, and they’re actually perfect for cleaning that out. Took out a fair bit of lint packed down at the bottom, and now the headphone plug goes all the way into the jack and clicks into place. Huh, it’s supposed to click — I had forgotten that.
So if your headphones start becoming funky, check for lint in your jack.
