I've had this PC for a year, the problem is that my PC shuts off when gaming, I play a game for atleast 20 minutes and bam it turns off, the GPU temp rises to 62C and stays there, CPU goes around 57C-64C, while I play I can just hear the PC fake shutdown twice, like you can hear everything stopping and starting again, but it just keeps working and it shutdowns the third time, I can also hear fire type noises coming from the computer, like if you've been close to a fire you'd know what I mean, also don't joke that theres a fire flaming inside, what I've done so far is I changed the thermal paste in the GPU and CPU which helped the temps, I've added 2 case fans, I've tried cleaning the PC and I tried using old drivers, nothing fixed the issue, the only thing that fixes it is underclocking it by a lot, what could be the problem???

Nvidia Geforce GTX 550 Ti
Intel Core i5-2400 quad core
500W Codegen PSU
4GB Kingston RAM
Windows 8.1 64bit

run Memtest for at least one full loop www.memtest.org

That's the first step always for issues like thus. After that it's basically swapping parts like the PSU or graphics card.

I use START8 from Stardock ($5) just in case you didn't know.

*The NOISES concern me though. Leave the side of your case open and investigate where it's coming from. You can STOP most fans safely by pushing in the center to see if it is fan noise (don't stop the PSU fan by sticking anything in there).

I did the memtest, what I did was I let it go till it reached Pass: 100% and then it just started from Test 0 so I just exited it, it said Pass: 0 Errors: 0, so what does that mean? And I think the sound is coming from the PSU, you can count the case fans out because the sound was there before I put them in. Also if you will want to know my 12v rail amp is +12V 1 says 12A and +12V 2 says 14A.

a) Errors 0 means no errors. Not sure why that's confusing.

b) Sound from PSU and crashing PC? I guess maybe you should replace your Power Supply. You can try PCpartspicker. You can get away with a 500W again but maybe get a 600 or 650W instead with 2xPCIe x6/8 for future proofing.
