My most embarrassing moment was the first time I redid a fresh windows install on my custom PC, I kept freaking out because it would only keep booting to the screen prompting you to install Windows... left the installation USB in...

[@Manarj789Games]

When you made the screen black, I thought something happened to my computer for a second was thinking it was terrible timing

[@bee_hall]

yeah he got me too

[@SSJFACPACIFIST]

I was thinking PERFECT timing lol. Since we troubleshooting

[@marvelousmarcus759]

I felt the same way

[@macbethmabena9816]

Lol 🤣🤣🤣🤣🤣

[@HughIrons]

@@macbethmabena9816 ah ah ah Mabena, you are also here?

[@julieuzii6350]

Thank you professor Messer for these videos. Taking my A+ backwards (WGU student) so I already passed my 1102, taking 1101 next week and feel confident. Then on to Net+ :)

[@jacobharris954]

Nice me next. I have a holiday booked to study

[@julieuzii6350]

Goodluck!@@jacobharris954

[@jaykekeola]

How did it go?

[@nickdestruct]

Great comprehensive beginner troubleshooting guide. I recommend everyone send this to all of their family members 😅

[@OJ-wy5oi]

I don't know what god of PCs smiled at me at 15 when I built my first PC, but I remember having to troubleshoot why my PC would shut itself down as a kid by using an upside down can of air duster blasting liquid CO2 at the CPU long enough for me to get to the BIOS to find out what was wrong. I had that thing for over five years after solving everything.

mans forgot the thermal paste

[@stevenpalermo7549]

Once you let the smoke out it's very hard to get it all back in there 🤣

[@ryanlea-nr8xm]

Everybody knows the Magic lives in the smoke : )

[@BlueGuardianSec]

Home Stretch Boys!

[@testotomboy]

and girls!

[@heathergoode302]

And girls! :)

[@spooney4064]

Messer you got me good with that one

[@davidseddon2157]

I literally jumped a little in my seat when the BSOD popped up 😂

[@tanusharma476]

Love that lecture

[@metavore7790]

I felt a jolt of panic at 23:30!

[@CryptoBeanie]

I once installed my RAM incorrectly somehow, when I was younger. I turned the computer on and saw a flash of light and a puff of blue smoke came out of the area where the RAM went. I immediately turned the computer off, prayed, installed the RAM right, and turned it on again. That computer went on to work for another 10 years before I finally just scrapped it for something else.

[@_ZERO]

lmao I cant believe that actually fixes it instead of looking at the PSU and cable connections computers are weird

[@anthonyjs8048]

Haha wow. The MFG missed out on some cost savings then, because clearly whatever went up in smoke was not necessary to include!

[@Kareem_da_Beam]

Thx so much for the content.

[@soulknight89]

I once had intermittent shutdown. It was my PSU. T_T Replaced and everything is running well. :D

[@danielskrivan6921]

I once let the smoke out of a power supply by overclocking the CPU.

[@kjayf.3425]

The black screen during the video had me thinking this new tv I bought had issues lol

[@L1LKILLER911]

What are those green and red things on the "grinding noises" section

[@ravisivakumar6339]

Hello Professor, thanks for all the amazing content so far! I just had my first question pop into my head. I remember in a previous video you were saying that you should never use a vacuum around any computer component because it can create charges. But in this video, you said it's fine for use on external ports. I guess my question is, are vacuums safe on external ports like at 13:30 of the video?

[@patrickbarber5807]

I had the same thought. From what I can find, cleaning anything externally (including ports) with a standard vac is ok. Internally is where you will need a battery powered vac to aviod static buildup

[@seanneff1597]

not sure on that answer but for my day to day deal, id prefer a bottle of compressed air. its a inconvenience to keep a vacuum everywhere you go when you can just keep a bottle of canned air in your car/desk/anywhere

[@anthonyjs8048]

@@patrickbarber5807 This is exactly right. The external case of a computer is/should be grounded thanks to the middle prong of the standard AC power cable, via the power supply. This means if your computer is still plugged in (but off, hopefully), any static that builds up on the vacuum head that may discharge to your case will be safely routed to the Earth, not to your components. Also, there are vacuums made for electronics that use materials that will not build up charge on their nozzle. It is general best to use these or compressed air cans instead of a standard household vacuum. I wouldn't use a vacuum on a case that isn't plugged in, or is otherwise not grounded. Nor would I use a vacuum on the inside of the computer ever, as it can physically damage things if you aren't careful (not to mention that once you open a computer, you should be unplugging it, which means you're now at high risk for static shocking it). Lastly, it is best to tape fans to keep them from spinning while you vacuum. some fans only want to spin one way, and some fans have cheap bearings that will wear out quickly if you have a vacuum on them.

[@RobertShane]

I put a tracker in my computer because my house got broken into. I connected it via usb so it would stay charged but for some reason, when it tried to connect to gps to update its location, it would make windows go into a bsod. I haven't found a permanent solution but in the meantime, I'm only charging it when my computer is off and unplugging it before I use it.

[@BenjaminSiegel-co5wb]

Speaking of abrupt noises or grinding sounds, my PSU recently died after using it for more than 8 years so this was all PTSD for me 😂

[@Dster9954]

That black screen got me 😂

[@denis75459]

14:31 That got me, I got scared lol

[@ian4846]

The first pc I built had no case fans. Still don’t know how I didn’t fry the thing
