    Computer freezes randomly when doing anything.


    I have recently (within the past year) bought and built a gaming computer. I had windows 7 on it and it was working fine for like the first 6 months. Then it randomly started freezing usually while playing a game or watching a video and sometimes it makes a buzzing sound when its froze and sometimes it doesn't. The only way to unfreeze it is doing a hard reboot. I did a fresh install of windows 8.1 praying it was a software problem but it did not fix it. It even froze when I first tried to post this thread! (only window i has open was google chrome) I did memtest and the memory check out fine. I also checked my GPU with OCCTPT and it checked out fine then i tried to test my CPU with OCCTPT and it won't even get a minute into the test without freezing and the temp of the CPU doesn't even have reach 60 C before it freezes. so I don't believe it is a overheating problem. I've changed bios setting and loaded default settings and everything. Anyway I am stumped and asking for help. Any help is appreciated thanks.

    Are you overclocking your videocard at all? I know that you said that you have tested your videocard, and your videocard maybe fine, but it does sound videocard related, it may just be driver related, I would suggest looking on some forums related to your videocard.

    No, no overclocking at all. I'll try doing the cpu test on the on board video and check back.


    Edit: It seems I do not have on board video my mistake I'll do some checks after my new psu comes in.

    Believe me, it's a temperature issue. It's not the CPU that's overheating, it's the mainboard. I also used to encounter frequent freezes with my mainboard - CPU combination as soon as I stressed the ĈPU. My mainboard is a Gigabyte GA-990FXA-UD7 and the CPU is a AMD FX-8350. Try maxing out all fans (CPU, GPU, any case fan you might got) and also try to stress your CPU with a benchmark/ CPU test utility while leaving the case open. My mainboard is even more sophisticated than yours (even though the same chipset) and my CPU is less powerful but it was the exact same problem. The CPU just draws so much power (yours even more than mine) that the mainboard cannot cope if the fans are not running at maximum speed. Oh, by the way, what's your PSU's maximum output? Once more, the top AMD CPUs just have insanely high wattage when running under full load.

    Edit: Just saw the maximum output of your PSU, 900 watts shoud be enough.

    Jut got a new 1000W psu and I have tried with case open and fans on max just bought new 2k rpm fans for the radiator and the cpu is still getting hot. Attached is my HWmonitor at idle now when it actually freezes up the bios says my cpu is 72-78 C. I'm using a CORSAIR Hydro Series H110 Extreme Performance Water/Liquid CPU Cooler by the way. Click image for larger version Also tried with a old graphics card on a fresh install no difference.

    Hm, 72 - 78 degrees is indeed high, my CPU never reaches such values. Could it be that there is a problem with your water cooling system? You posted a HWMonitor screenshot under idle conditions. Could you post the same when the system is running under heavy load? But I don't know if you manage to actually save the screenshot before your system freezes. Being able to take a look at the values would certainly help judging the situation and narrowing down any possible sources of the problem.

    Under load it hits about 70C before it freezes and if i instantly reboot the bios says anywhere from 75C to 80C. i can feel the water pumping on the cooler but that doesnt really mean anything.

    70 degrees with a water cooling system? That's way too hot. And you are sure that you are running your cpu at it's intended frequency/ voltage? If that's the case I'd say your water cooling system is malfunctioning. Enough coolant in the system? No leaks? Radiator intact? Fans mounted correctly? Have you already tried to replace the water cooling system by an ordinary cpu cooler in order to test if the cpu also hits those high temperatures when running with an air cooler?

    FX-9590 is essentially a factory highly overclocked FX 8350, at stock speeds requires 220 W which is too much for UD3 so it's very believable that power section can't handle the load.
    A friends Gigabyte GA-990FXA-UD7 and the CPU and a AMD FX-8350 system (that I put together) is the only one I found that can sustain 5 GHz for any periods of time. It's not under water cooling but CM 616 Evo air cooler and stays under 60c at full load.
    You can try testing with frequency lowered and see what happens, drop to 4.5 GHz or lower and start from there.

    That was my first shot and I still believe the Gigabyte mainboards in general and particularly the GA-990FXA-UD3 are struggling as soon as the cpu is under full load. Like I wrote it's also the case with my 8350 and the GA-990FXA-UD7 mainboard. Nevertheless, 70+ degrees cpu temp using a water cooling system is way above any reasonable temperature. There got to be something wrong with the op's cooling system.
