What Do You Do If Your PC Started Smoking When You Turn It On

Just rebuilt my gaming pc after cleaning out all the dust and rewiring everything with proper cable management. When I turned it on one of the top fans didn't spin and I saw a small puff of smoke rise up from the case. I turned it off instantly and smelled something like burnt hotdogs.

What do I do? 0_0

Unplug everything

 

EDIT:

 

Take each individual piece out again, try to locate where the burning smell is coming from. This is most likely a PSU failure but its possible that something else got burned out due to using a wrong cable

Pray for my soul. It was booting just fine but that one fan didn't spin and the smoke came out of that area.

Might have blown your PSU, or even worse your motherboard, which would have comboed with quite a few other things likely.

Take the smokes off it and lecture the shit out of it

 

jks, sorry couldn't resist

 

Isolate the power and have a good smell around see if anything burnt, even if you smell bad stuff, it doesn't mean it's dead. However you need to figure out what caused it so re connect all the PSU cables and check motherboard stand offs

you might have a short somewhere

 

hopefully the PSU is the goner

 

otherwise the mobo might be fried

Fan short then, make sure you plugged it in correctly, I did that before.

Call AMD and ask who had the clever idea of selling a 220W CPU to OEM?

The only thing I took out of the case while cleaning it was the GPU. I'm going to unplug all the drives and take the GPU out again. Smell seems to only come from that one fan.

Inspect the parts for any kind of burnt pins, components, and/or insulation. You may not have connected something properly, like a wire for ground connecting to power(just as an example).

That fan has a 2 pin connector and a molex. I plugged it into a 3 pin slot. I find it odd cus the other fan I have next to it is the exact same model plugged into a 4 pin slot. Should I try turning the PC on without any drives, GPU, and without that fan?

The LED on the power button on the mobo is still on. Should I try turning it on again without that fan and most components connected?

Yep. Though be ready to flick the power off just in case.

It booted just fine. Crisis somewhat adverted. Although I now I have 2 other problems. The other fan of the same model doesn't spin but it's LED lights up. Also my case is an Arc XL which comes with a fan controller. I hooked up the 3 fans that come with it to it but none of them spin. Actually no fan I have connected to the fan controller works.

Try connecting the fans (apart from the dead 1) 1 at a time to the motherboard. The fan controller might have been what killed the fan.

 

Edit: Though the fan controller shouldn't actually die if its similar to what my case has, its got 1 Molex in to the 2 switches (which have low-off-high) which then goes to 2 front fans for the first switch, and 2x top and 1 rear for the second switch.

 The dead fan was connected directly to the mobo. I connected a spare fan I got to the same slot and it didn't spin either but it did spin on the other slots. So the slot doesn't seem to work anymore. 

The fan connecter was a separate issue. I had that problem before and I wanted to open up my pc and fix it but no luck. Before I had my red LED fans connected to it (including the dead one before it was dead) and none of them spun, so now I swapped them for the default case fans which the manual said would work but still no luck.

 

EDIT: Mine has a molex and 3 3 pin connectors, as well as a 5 7 12 volt switch.
