Computer freezes while gaming with buzzing sound

[Khaleal]

Hi,

I have a PC with the following components:
CPU: Core i5-3350P 3.1Ghz
MB: Gigabyte Z77-D3H
RAM: 2x8GB HyperX Fury 1866MHZ
GPU: ASUS R9 280X
PSU: CORSAIR TX850M
SSD: 2xKingston HyperX 240GB
HDD: 2TB Seagate Barracuda HDD

My PC freezes randomly while playing games with loud buzzing sound and I have to hard restart it in order to get it working again.
- This may happen right after I play the game for 5 minutes, and maybe after 2 hours, and sometimes doesn't happen at all..
- This issue doesn't exist in Benchmark like FurMark and stress tests like prime95.
- The max temperature on the GPU while gaming was 72C (76c while bench-marking) and 52c on the CPU while stress testing using prime95.

Troubleshooting steps that I've made so far:
- Clean installation of Windows 10 with latest drivers from Gigabyte website.
- Clean installation of AMD latest drivers from their website.
- Replaced PSU with CORSAIR TX850M and that didn't made a difference (I had CORSAIR VS550 before)
- Ran mem86 and the RAM passed

Yesterday, I removed the pair of Kingston HyperX 8GB 1866MHZ RAM sticks (I got them in one package) and replaced them with one stick of Kingston ValueRAM 8GB 1333MHZ and until now the freezing issue didn't happen at all.

What could cause such issue?

All I know about that card is that it doesn't support 1920x1080

Do you mean the GPU? It can handle most games at 1080P at highest settings without a single issue.

It turned out to be an overheating stick of RAM. RMA'd the RAM and problem solved.
