PC freezing and making loud buzzing noise in speakers/headphones.

[liran321]

Hello all,

I've been having this problem for a long time now (2 years) and no matter what I do I can't get rid of it.

My PC will freeze and make very loud buzzing noises a few times a day,even when left idle in the middle of the night it will sometimes wake me up with the buzzing sounds coming out of my headphones.

I'm clueless at this point as for what to do,I replaced my Motherboard,my network adatper, I disabled my sound card,played around with the BIOS settings and nothing works.

There is one way which seems to consistently recreate the freeze & buzzing sound and thats only when I run low graphic games and let me explain:

I can play heavy 3D games with demanding graphics and the PC wont freeze (Actually don't think it ever froze while I was playing a 3D game) however It will freeze after less than 10 minutes if I play a low demanding game like Stardew Valley,League of legends or even when the PC is just Idle or while listening to music on youtube.

I ran Memtest86 and Prime95 and didn't find any errors and the event viewer errors seem to just say its Error 41 which is an unexpected shutdown.

I would really be greatful if someone can help me solve this annoying problem for once and for all,I've been living with it for so long,it makes me paranoid when I'm gonna hear it while listening to music (the sound gets you jumped every time..)

My system specs:

Computer type PC/Desktop

OS Windows 7 Ultimate x64

CPU Intel i5 2600K

Motherboard Gigabyte H-77 DS3H

Memory Kingstorm 4GB x2

Graphics Card AMD Radeon 7870 HD

Antivirus AVG Antivirus

Browser Chrome

Appriciate any future help,

Liran.
