One computer case fan, keyboard, one GPU fan, monitor, and possibly other components stopped working

Hello,

So I was playing CS:GO, then suddenly everything noted in the title apart from the one GPU fan just stopped working, and when I restarted the system the GPU fan stopped working although at some restarts it did work. I built the system a few years ago and I have had some oddities now and then like the screen showing red lines for a split second and it shutting off with a messed up screen or just a blank screen, but it has never stopped working like this.

I have tried reconnecting cables, the CMOS battery, the RAM, the fan that stopped working, and the processor. I also tried to connect the HDMI cable from my monitor to the integrated graphics but I had no luck with that either. I haven't got any spare parts apart from some case fans.

PS: I didn't have any food/drink items with me at the time so it can't be a spill.

Another side note: The light in my mouse is emitting light, but my keyboard isn't. But it should, so I am pretty sure that they are getting power.

  1. Follow this troubleshooting steps:

    I suggest you to first do the breadboard test (described after step 23 I think) and then apply the steps listed in the link.

    I will do that when I get my motherboard speaker, because I haven't got one since I never thought I would need one. Also, I just tried starting it again. But it kept restarting itself.
  3. Those "oddities" you talked about were a warning sign that something was wrong. Either something was overheating or failing before this issues, and just finally broke. If intergrated video does not work (assuming you removed the video card before you tried), it points to the power supply, motherboard or possibly RAM. Need to swap those out for working units to narrow down the issue.
  4. I fixed the problem by taking the computer apart, cleaning it, putting it together again and resetting the cmos battery.. I have no utter idea why that would work but it did

    See how long it will run without issues, I'm thinking not for long unless it was just overheating and your cleaning it out cured that.
