My PC randomly restarts without any BSOD when stress testing the GPU or gaming.

random restart:

  • furmark: setting was only fullscreen, 1920x1080, 8x MSAA,dynamic background and post-fx. Restarted when it went somewhere around 73C which was 15-20 min of the test

    3dmark demo: Only did 2 run.1 run restarted at sky diver's combined test while another run went smooth.

    TERA (STEAM): This game rarely restarts it. Play in best setting

    Black Desert Online JP: Restarts frequently. Setting is at best graphic. Sometimes I can play for hours but mostly it restarts after I choose the character to play.

    none of the temperature goes past 75 so I don't think it's overheating

never restart:

  • FF14
    GTA V
    Dynasty warrior 8 Xtremem Legend
    DOA 5 Last Round

    All these were played in best setting too except for GTA V


My rig:

  • CPU - AMD FX-6350 Black Edition
    MOBO - Gigabyte 970A-DS3P
    GPU - Sapphire Dual-X OC R9-280 3GB DDR5 384bit
    RAM - Kingston Desktop DDR3 8GB PC1333 16 Chips
    WLAN - TP-Link TL-WN781ND
    HDD - WD Desktop Blue SATA 3 1TB
    DISPLAY - AOC E2250SWDN
    PSU - CORSAIR VS series 650W
    CASE - Thermaltake Versa H21
    SYSTEM - Windows 7 64 bit home premium

This is my first DIY desktop and its only been around 3 months since I bought these. I really have no idea on what the problem is and where to start looking for.....

I see.... a faulty PSU.....maybe that explains the weird static like sound when I use the desktop sometimes. It doesn't do that anymore so I thought it was more of a just bad current from the socket.

Sadly I have no other PSU to check if the PSU is faulty....

Is there any chance it was the GPU that is faulty?
 

Sometimes you can get coil whine coming through your headphones, assuming that's what you mean? I had it when I build this pc, it was from the graphics card, but it went away after a few days.
A faulty GPU will usually crash the graphics drivers, artifact or display no signal, it's unlikely it is that.

I dont think its coil whine. It makes the static like sound just by having the psu switched on (the back switch only). the desktop is itself is switched off. so the sound is there sometimes even when im not doing anything with my desktop. i dont hear it anymore though or just less frequent
