My computer fans, CPU fan and leds light randomly turned off ?

Alright so right now i just turned on my PC so im downloading a few updates on steam and all that stuff. But then all of a sudden my case fans, cpu fans and my GPU led lights randomly turned off. (Keep in mind, i have my lights in my room turned off and it kind of scared me a bit) So i want to know what just happen ? I was still able to use my PC but as soon as i saw everything turned off i opened up MSI afterburner and it showed the temps at normal rate. Then i just tapped my pc case and all the lights, fans started running again. I did have a problem playing CS:GO about 2-3 weeks ago where i couldn't join a game but once I did join a game i had a black screen and i coudnlt return to the Windows 10 home so i had to turn off my PC manually and power supply. Or I'm not sure if this is because of a few Windows update's i downloaded the day before yesterday is it ? So what happened ?

    How old is the PC and when did it last get a spring cleaning ?

    Was there perhaps a power burp ?

    I blow out all the dust quarterly and once a year every machine gets a tuneup, each cable gets unplugged and re-plugged, each component in a slot gets removed, tabs cleaned and reinserted.

    Windows 10 is certainly causing a lot of strange behavior and headaches but I don't think this is related. probably just a bad (dirty) contact point or loose cable.

    My PC is 6 months old.

    Whats a power burp ?

    Also i want to know should I do a system restore to a previous date ? Could that help ?
  3. 1. I have had calls where brand new PCs arrived via UPS and the gorillas who handled it musta shaken it up enough that some cables actually came out. Better do the unplug / replug thing at earliest opprtunity.

    2. Power burp is just like yours...there ya are breathing in and out and your breathing is interrupted by a short interruption. You will see the lights and TV flicker but power wasn't gone long enough to make clocks flash and require you to turn the TV back on.

    3. All evidence points to a hardware issue....there's nothing you could do to windows to make fans and lights stop other than the normal reboot process

    Okay i want to say that me and my friend built PC i didn't come like in the mail. Also i just did what you said and unplugged and re plugged all the cable to see if its fixed or not but ill have to see in the upcoming hours. I see that there is a lot of dust in my PC using 6 months straight. So i should buy air compressor right ? Sorry if i sound like a noob, I just switched from console to PC gaming and I just remembered that my buddy said that i have to clean my PC once- twice a year.
  5. I de-dust every 3 months ... but all our boxes have air inlet filters, not all do.
