Hey guys, so I made a thread about this in the past, I couldn't figure out the problem fully, so I'm back to see if I can get it sorted, and help would be fantastic! Also, wasn't really sure what category, so apologies if there's a better place.

Motherboard: Gigabyte Technology Co. H55M-USB3(socket 1156).
Processor: Intel(R) Core(TM) i3 CPU 550 @ 3.2 GHz
Power Supply: Corsair Professional Series™ HX650
Graphics: NVIDIA GeFore GTX 560 Ti

So, basically my computer is crashing occasionally after it's been on for a few hours, though the crashing is almost entirely restricted to when I'm playing a game, or watching a video.
The screen seizes, the last sound repeats and the power has to be turned off, just before crashes, 3-10 seconds before, the computer starts stuttering, sounds repeat and computer seizes up for very short periods, occasionally the computer will just stop stuttering and keep working, otherwise it crashes.

What I've tried:

- RAM dancing and running memtest, no errors.
- I've fully replaced the GPU since the issue began happening.
- I rolled through all the GPU drivers I could find and none of them helped.
- Replaced the cooling unit on my CPU and ensured all the temps on my PC are good, which they're all fine.
- Downclocking the GPU

Additionally, I am in Australia, so it might be something to do with the heat? I'm lead to believe this because the crashes are entirely non existent when I have an external fan running aimed at the computer.
The problem with this is that I'd like to be able to just fix the error so I don't have to worry about it, but all my temps are more than fine.

Cheers for any help anyone can offer, if you need me to elaborate on anything, just ask.

Hey, sorry about the late reply, I just reinstalled the sound drivers, so I'll see how that goes, with everything that I've tried I wouldn't be surprised what it was at this point. Cheers, I'll keep the thread posted if something happens.
