Computer Turning Off After About 1 Hour and 15 Minutes

Hi, I'm new here so please bear with me.

I built a PC about a year ago with the following components:

CPU: AMD FX-6350
GPU: MSI Radeon HD 7870
Motherboard: Asus 990fx r 2.0
Memory: 8GB Kingston HyperX
Power Supply: Corsair CX600
Hard Drive: Seagate 500GB (Don't remember exact model)
Case: Corsair 500r

I know the case and the motherboard are overkill for the rest of the specs so please don't comment about that I know already sorry I wasn't an expert at PCs when I bought them.

But back to the point. The thing worked beautifully for the first year. Then, about 4 months ago, it started radnomly turning off. I already know it's not temperature, considering I monitored the temperature and it turned off with my CPU being at 41 C. The case also has 7 fans.

I'm not sure what's going on. Maybe I downloaded something weird or the GPU is overheating. I was just wondering if anybody had any suggestions as to what I should do?

  1. Nothing wrong with the Corsair 500r, its a really nice case. oops iv'e commented.
    Download HWMonitor to view voltages on all rails of your PSU and to monitor your temperatures under load using a stress tester.
    The CX series PSUs are only bronze certified for general purpose use. You have a moderate to high end system and peak demand makes your PSU borderline in terms of efficiency.

    Conduct a memory test using Memtest86+ to determine if your DIMMs are OK.

    Post the results as we may have to dig deeper.

    Hahaha yeah I like the case too it's just that there's been too many times where people just say it's too good for the other components blah blah blah.

    I downloaded HWMonitor and HeavyLoad to run the stress test and monitor the temperatures and voltages. At 100% CPU usage and 15 minutes of HeavyLoad running, it looked like this:

    I'm still working on getting the Mem Test on my USB but I'll upload as soon as I get it.
  3. Ok that's the PSU done and indicating that all is OK re voltage on all rails. Your temps look good too and acceptable under load.
    Next to eliminate any probs you may have with your DIMMs

    Okay I did the MemTest86 and I got the results:

    Well done Luciano, you have eliminated your DIMMs as a possible problem.

    Now we will turn to your operating system.
    Open a command prompt as administrator and type in the following: "SFC /scannow" without the quotation marks.
    This will search your OS for any corrupted files and attempt to fix them.
    Report the results.

    Next to test is your GPU so download MSI afterburner.
    Have you OCed the GPU at all using AMD overdrive?
    Go here for Catalyst Control: http://support.amd.com/en-us/download
    Make sure your GPU driver is up to date.

    I ran the OS test in the command prompt and got these results:

    I updated the drivers. And no, I never OCed the GPU. I have Afterburner but how do I run tests?
  7. OK no corrupted Windows files. That's that out of the way.
    Take your time with testing, your in no hurry.

    Ok I am updating the rivers and going to see if that's the problem. If that isn't it how do I run tests on it?
  9. Well the only other way is to test it in another system or your local computer store can test it.

    U updates the GPU drivers but the same thing is still happening. What now?
  11. Describe what you were doing when the system crashed and when.

    I don't have to do anything for it to turn off. It happens if I just leave the computer idle and with nothing open. It happens if I'm playing something like WaW. Or just surfing the internet. It's also always every hour. I timed it a few times. Also, it doesn't suddenly crash like a black screen. I guess this may have been important to mention, but the computer closes
  13. How are your sleep states setup?
    In Windows 10 you can check when your system either goes to sleep or Hibernates.
    Right click on your desktop and choose personalize>"Power and sleep" in the search box>choose "never" to prevent sleep mode.
    In BIOS find C1E states and disable.

    To check your sleep settings in W7

    Open Power Options by clicking the Start button Picture of the Start button, > Control Panel, > System and Security, and then clicking Power Options.

    On the Select a power plan page, click Change plan settings next to the selected plan.

    On the Change settings for the plan page, click Change advanced power settings.

    On the Advanced settings tab, double-click Sleep, double-click Sleep after, and choose your preference.
