It hit a tree less than 5' from the wall I was next to. Packaged fluorescent tubes glowed so hot they melted the plastic shrink wrap to themselves. The EMP induced a voltage in the network wiring that destroyed every computer nic instantly and everything else in the case failed over the next week. 20+ systems and all hard drives, backups, tape controllers, monitors, every part. All TVs and radios failed within 2 weeks. Luckily, the brand new first gen 64-bit AMD server for a customer was spared. Too bad my workstation with same parts was not.<br><br><div class="gmail_quote">On August 10, 2020 5:18:13 PM EDT, David Jackson via Ale <ale@ale.org> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<div dir="ltr">In case anyone else would care to share, here are my top three:<div><br></div><div>1) One day I noticed a recent (2-yrs ago?) build was running hot. I checked the fans and power and BIOS OC settings. Hmmm. No problem. I removed the cooler from the CPU and then I noticed there was a thin plastic "peel-off" sticker on the bottom of the copper heat plate with the words "remove before use" in bright red on the plastic. I noticed this after I cleaned the thermal paste. Oops.</div><div><br></div><div>2) I purchased a spiffy new GPU entry-level gaming GPU. I installed it, and turned on the power, and no video or POST. I looked and looked again, couldn't find the problem. So I returned the card to Microcenter, bought another copy of the same card, and installed it again. This time when it didn't "work", I hesitated before returning it to MC. I noticed that this card had an auxiliary 8-pin power connector I somehow hadn't noticed. Oops.</div><div><br></div><div>3) Before I learned about negative vs balanced vs positive case pressure, I installed too many LED exhaust fans on cases and couldn't understand why I had so many dust bunnies around the intake filters. They were pretty and color-coordinated LEDs, but, um, it got hard to see the colors through all the dust bunnies.</div></div>
