    Hi, I'm trying to help my very frustrated teenage son with his PC that he's built himself. He's confident that he's bought components which should all be compatible but on running graphically demanding games (and "some" benchmark tests), the computer keeps freezing and requires a hard reset. I'll try to detail the problem as bast I can:

    PC Specifications:

    Motherboard: MSI Z170 TOMAHAWK
    Processor: I5 6600K (3.5 GHz) CLOCKED TO 4.1 GHz
    Cooler: SPC FORTIS 3 v2
    Graphics Card: XFX RX480 GTR 8GB
    PSU: CORSAIR VS650 650w
    RAM: KINGSTON 2133 8GB
    Windows 10 Home 64-bit

    Benchmark Tests:
    Prime 95 - runs fine
    FurMark - runs
    Heaven Benchmark - crashes PC after 30secs - 1min (freezes, hard reset required)
    Fallout 4 (any presets between Medium - Ultra) - crashes PC after 30secs - 1min (freezes, hard reset required)

    Some other points to note:

    • The PC always crashes in the same way - a solid colour fills the screen (e.g black, white, orange, brown) and the speakers emit a loud buzz. It is then completely unresponsive and requires a hard reset.
    • This was a fresh installation of Windows 10 and all updates have been installed
    • All drivers for all the components have been updated from the manufacturer's websites.
    • He has tried default settings, overclocking and underclocking the GPU and CPU with no effect.
    • He tried increasing the voltage to the GPU a little, with no effect.
    • The PC operates fine browsing the net, watching YouTube, working with documents, etc. It only freezes during more graphically demanding situations, but even then it's inconsistent because FurMark is designed to push the GPU to the max, and it runs fine.
    • The GPU never reaches more than 79 deg C and the processor never over 65 deg C

    I would appreciate any advice. Many thanks.

    I've never built a computer and I'm not a hardware/gaming expert, but I'm pretty sure the ones here who are will advise you to get a better quality power supply.

    1. Welcome to Tech Support Guy
    2. You say that you have tried
    however on your spec you post
    be assured please that troubleshooting a problem of this nature can ONLY ever stand a reasonable chance of success when everything is running at default values
    That processor the i5 6600K has a default clock speed of 3.5 and a mx turbo of 3.9GHz, whilst it is an unlocked core indicated by the K and can be further clocked - going to 4.1 is not good practice, and certainly not until you have a stable system to start with.

    Furthermore its max TCase is 64C - Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).

    3. With your Fortis cooler
    it most certainly should NOT be reaching anything like TCase

    4. The CPU is supported fully from BIOS version 1.9
    see compatibility for motherboard
    CPU listing
    If you do not have that BIOS version you should most certainly flash AFTER returning all settings to default and running ram at SPD - serial presence detect- which is default see below for instructions on MFlash

    5. You do not say which Kingston 2133 there are a number
    Again see compatibility for ram on MB - although doubt that is the cause
    DDR4 ram will run at 1.2V SPD

    6. Please consider the above points
    CHECK carefully the seating of the cooler and unless you are absolutely certain of the correct application of the thermal compound I would consider that a strong possibility in view of reported temp of cpu - if the reading is accurate.

    7. BIOS flash

    8. Finally for this post I thought that XFX card was already factory overclocked at BIOS level by XFX
    Indeed the standard 480 runs at 1120 base 1266 boost

    whereas the XFX is OC to 1338MHz

    If I am correct I cannot understand your attempt to increase voltage -
    In fact IMHO you are fortunate that you have not suffered damage to it - depending on increase

    Additionally what case please and what cooling by case fans etc
    MAYBE inadequate case cooling

    This just jumps out at me;
    The vs series from corsair is for a low pw, basic system only. Even corsair says as such;
    Attempting to run that pw supply with a rx480 is just asking for a problem. The very first thing I would do would be to swap in a quality pw supply for testing. Good ie recommended brands; corsair [AX, HX, or RM models ONLY] seasonic, FSP [only units with the 5yr warranty] or antec [HCG models ONLY]

    As a simple test, restore ALL bios settings to stock. Pull the video card out and use the onchip video that is part of the 6600k. Test temps and voltages while the system is under a normal load and while loaded to 100% Use either prime95 or IBT for stress testing. Use the msi command center to monitor temps and voltages. Download command center from the support page for your board. Here is a link;

    Post the following; cpu temp, 12V, 5V, and 3.3V values. Do this twice; once under normal load and once while stress testing.

    Thank you all for your suggestions so far. We're looking into the power supply situation which most people seem to think is the place to start. I'll post our findings asap.

    Thanks again.
