Worst Tech mistake you have ever made?

[Extingquish]

I had a network card droop down onto a graphics card when the system was on, needless to say, it died instantly

[Sors]

I tossed some CRT monitors from a 2nd floor when we were cleaning the old office before moving out.

[Lotus]

I haven't done it, but a long time ago I saw someone cut down the pins on their GPU to fit a x16 card into a x8 slot...

[GlassBomb]

I am keeping my 4930k and 780 trapped in an Antec Sonata III...

[Dive5885]

When I tried removing my Gpu out of the PCI-E slot and I pulled the Gpu and slot together.

 

Biggest fail ever.

 

Had to order a new motherboard right after that happened..

[WobblyMusicStand]

Helped a friend build his first computer. I mounted the RAM into the wrong pair of slots to start with. We then spent an hour and a half panicking and wondering why the machine would post but then fail to recognize the keyboard or mouse in the BIOS.

[cluelessgenius]

miscalculated a powersupply for my buddys build. so after it ran just fin and then we stress tested it for the night and after running the whoole night without any problem it crashed in the morning. grilled the psu and replaced it for a better one at my own cost as it was my fault to miscalcutlate it.

Oh my hahaha yes. I have some stories to share:

 

1. 3 years ago I was building my own pc , after sooo loooong . I placed the CPU the wrong way and actually FORCED the latch and locked it. However upon reading the instructions on the CPU, there was two small hinges to indicate how to put the CPU properly. I bent some of the pins on the motherboard and had to do the unbending process haha.

 

2. Built a PC on a Carpet. OOOOOooooOOOO boy was I lucky nothing happened. 

 

3. I took off the small jumper on the power connector ports thinking it was just a regular cap. HAH. 

 

4. I didn't know that the latest PSU's won't run the fans until a certain load is reached. I thought my PSU was a dud lol

[CowsForBreakfast]

I recently found a screwdriver that I left inside the case months ago. That also solved the reason why there was vibrating sounds within the case.

[BraxtonPC]

Bench tested a motherboard on an anti-static bag. 

Facepalm

[Tedster]

Forgot to put the backplate in.

[Thomas Piccione]

Chose a motherboard that does not support analog fan speed control. GROWL!!!

[RedSphyxis]

So I remember my first pc build it was with a e7 something I think it was from a codename Wolfdale can't  remember. And my pc was all set and done and i was ready to add my connections.

 

That was the time I realized that I hadn't attached The motherboard's I/O shield.

 

ine's not that amazing, but care to share yours?

[TheKDub]

I believe that when building my first PC I forgot to put the I/O shield in, luckily I had not put any mobo screws in yet.

 

Didn't really manage to fuck anything else up with it that I can remember.

[MRE Teck]

Not much a mistake but I went with a corsair h 50 for my cooler and I didn't realize the asrock fatal1ty z97 killer didn't go all the way to the right with the standoffs bps of watch out for that on mobos

[dadasmithywinkle]

I don't really have any. 

[Oshino Shinobu]

Those damn front panel connectors. 

 

I still frequently forget to turn the PSU on at the back, and sit there for ages trying to figure out what's wrong with it

[The Crazed Child]

my first build went smoothly, however there was a couple of times when i forgot to reconnect the CPU fan after reapplying thermal paste

[babadoctor]

good to know!

[MattTheMayor]

pc didnt power on, thought i broke something. freaked out for 25 minutes then noticed i didnt plug in the 24 pin all the way

 

not sure if its a first build, but first time rebuilding (cleaning). i forgot that there was a latch thingy on the pcie slots so i just tried to yank out the video card, the mobo was like bending it was really cringe worthy

[XTankSlayerX]

Dropped the i3, the I placed the i3  in to the Asus P8Z77V-PRO.

 

I KNOW I MESSED UP

[MrMineHeads]

Bending my GOD DAMN case panel. Takes forever to put it back on. 

[Nickolas47]

Breaking the clips on the front of a turbo-x case (greek brand)

[RyomaSJibenG]

installing the hyper 212 is a pain in itself, even now its still tilted a bit when i looked through the window side panel =/

[Ja Krispie]

I bought AMD
