Unidentified sound from my computer causes freeze when gaming?

[Fafaagasta]

Its been a month I have this issue. This sound I cant identfy but actually I can always hear it everytime I turn on my pc, but I dont know whether its from my GPU, CPU, or HDD. However, nowadays when I play some games, I hear that sound (never hear that before unless I turn on my pc) and after the sound, my game will freeze about 30 seconds then back to normal again. I heard this sound more often when I play games in high/ultra settings like in Battlefield 4 and Crysis 3, but when I lower the graphics, it will occur less. Also, the freeze acts differently in different games. In Battlefield 4, it will freeze everywhere in the game, but in Pes 2018, if the sound heard, there will be no freeze, only the loading circle will spinning about 30 seconds if there is a progress, but if the game is on field, there is no freeze, only the commentary will stop about 30 seconds while the game still on. In Crysis 3, after the sound, I can still go around, but all the AI wont move (They freeze) and when I try to quit the game (press ESC) it will freeze until 30 seconds then the menus show. And I never hear the sound when browsing or watching movies. I suspect my PSU causes this problem. Its a cheap PSU ($20) and already use it for 2 years without problem. I assume the PSU couldnt handle my components with those games. Could it be the PSU keep resending power to either CPU, GPU, or HDD and causing it to stop and restart (thats why I can hear the sound when I turn on my pc?) Or? I dont know man, help me...

This is my system
Windows 7 Ultimate 64bit
Gigabyte motherboard G41MT-S2 LGA 775
Intel Xeon X5460 3.2ghz
Nvidia GT 1030 Asus Phoenix
Seagate Harddrive 320gb
4gb Ram ddr3
Cheap 500w PSU (I forgot the brand)

Anyway, I never overclock everything...

You first need to determine where the noise is coming from, and then what is making the noise. It is possibly a fan trying to freeze in its bearings. If this is a CPU, GPU or PSU fan, then those components are possibly overheating and causing your freezes. You are going to have to remove the side panel from your computer, and when it starts to make the noise, use a screwdriver as a stethoscope: touch the metal end to the component you are testing and the plastic handle to your ear. You'll be able to easily tell where the noise is coming from.

While a dying PSU could certainly cause chirp and ticking sounds to come out of the speakers (or even the PSU itself), the more common consequences system-wise are outright crashes, shutdowns and random restarts.

Replacing the generic $20 PSU with a decent quality one would be an advisable first step regardless of whether it'll solve your problem.
