Solved

PC made a popping noise, turns off randomly and is very hot!

Specifications:

CPU: Intel Core i5 - 3340s CPU @ 2.80 GHz ('Turbo' mode enabled @ 3.30 GHz)

RAM: 8.0GB DDR3 Corsair CMX8GX3M1A1600C11

Graphics: NVIDIA GeForce GTX 650

Motherboard Manufacturer: ASUSTeK COMPUTER INC.
Motherboard Model: CM6330_CM6630_CM6730_CM6830_M11AA


The Situation:

Last night I left my PC on to finish some updates. While I was sleeping, a thunderstorm took place pretty close to our house.
I woke up to a little popping noise (Lightly clap your hands together, that's sort of what it sounded like), I assumed it emanated from my computer.
There was no smoke or weird burning smell.
I panicked and turned it off, the pop obviously hadn't caused my PC to power down on itself. I turned the PC off normally and I went back to sleep.

This morning, I booted up my PC as normal and remembered the events of last night. I checked my PC's temperature - it was pretty normal (~ 29 Celsius idle).
I booted up DoTA and played for about 3 hours. Suddenly, my PC turned off. I quickly booted it up again and re-joined.
Mid-game, I thought about my PC's temperature again. I tabbed out and opened up EVGA Precision X.

My GPUs temperature was at 60 Celsius. I immediately shut down DoTA and turned my fans up a notch.
I grabbed a torch and peered through the window on the side of my computer. As far as I can tell, all of the fans are working.
I've not heard the pop since.
I put two and two together and assumed that, perhaps, my PC had turned off because it was overheating?

I had a similar problem with my previous CPU. The PC would often turn on randomly during the night and rapidly flash on-and-off after shutting down.
After buying a new CPU, this problem seized.

My PC is plugged into a surge protector, surely my PC couldn't have been messed up this easily. I'm really low on cash and can't afford to buy a new CPU / PSU / GPU.


Any help would really be appreciated, if I missed out anything, please give me a shout.
Sorry for the really long post. xD :P

Solution:
My PSU is poor quality. Something must have popped during the power surge.
Both rounakr94 and Blackbird suggested that I purchase a XFX 550W as it is considered a high quality, budget PSU.

  1. What about the fan on your CPU? You might need to take the cover off to look. What type of CPU fan/heat sink combo do you have? Keep in mind that this issue may be unrelated to the thunderstorm.

    Incidentally, even though all of our electronics are plugged into surge protectors, we power everything down at night and whenever there are thunderstorms in the area, just to be on the safe side.

    Hi, thanks for the response! :)
    My case has a big window on the side that displays the majority of the innards. The fan on the heat sink, GPU and the other fans dotted around the case are all spinning. It's definitely not quieter than it was before the mysterious popping noise.

    I'll take off the side of it later to have a closer look.
    Another strange incident I had, is that when I put it into sleep mode, it stayed on. The fans were spinning, etc. I decided to hold the power button down, but when I pressed it the PC turned on as if it was in sleep mode (But it on the whole time, SPOOKY!)

    If I have any other incidents, I'll update. I'll take a closer look at the PC in a bit, thank you! :)

    note: Also, I've kept the fans at 50% speed since the shutdown. The temperature has stayed at ~30 Celsius while I'm watching YouTube and stuff. Is this considered 'normal'?

    Your PSU must be faulty
  4. A capacitor could have popper in your psu

    Hm, perhaps.
    I have another PSU somewhere in my drawers. I'll try plugging it in later and see if it makes a difference.
    Thank you guys for the responses, it is well appreciated! :)
  6. What power supply do you own?

    Sorry for the late response!
    I decided to have a go at opening my PC. I followed usual safety precautions (Tapping the metal on the inside to get rid of static electricity, unplugging it, etc.)

    It was pretty difficult because the screws to the panel were tightened.

    Anyway, I found out that the power supply I have is a 'G7 Power Extreme 580w'. I hope that somewhat helps.
    Thank you for the response! :)
  8. They are very very poor power supplies.

    Here's what happens with cheap power supplies.

  9. I suggest you to get a XFX Core Edition Pro 550W(PCB and Caps by Seasonic USA) as it will be enough for your system.

    I assume that this (http://www.novatech.co.uk/products/components/powersupplies/p1-550s-xxb9.html) is the one that your talking about?
    Would you guys say that it'll be 'safe' to use for another few days before I manage to afford it / the delivery arrives?

    Also, the video that Blackbird linked to creeps me out. I had a problem exactly like this a while back and never bothered to check it out.
    I used the same power supply for another year before getting the one I currently have. Thank god it didn't explode or something. xD D:
  11. Get XFX 550W.

    It's a high quality power supply.
  12. Yes thats the PSU we are talking about.
