Computer Randomly Freezing Up Don't Know Why

So I'm at a total loss and can't figure out what's going on.

Sometimes my computer will freeze up under heavy load meaning Pandora, Counter Strike and a bunch of tabs open or sometimes it will just freeze up if I'm listening to Pandora while browsing the web. It can be sporadic and sometimes it won't happen for a day or sometimes it will happen twice in a row..

This can also happen if I plug in a USB device to case USB.

I can't get past Prime 95 Blend test for more than 30 secs. Changed out the ram as well, same result.

Idle temps are in the teens and at load around 40 for the CPU and 50 at most for the GPU. Using Corsair H100 so not really any temp issues.

My specs:

AMD FX-9590
M5A99 FX PRO 2
Ballistix 8GB Tactical x2
Antec 750W

I don't think it could be the ram as I just changed to the Ballistix from AMD Radeon Ram and same thing.

Any guidance would be greatly appreciated.

Possible thoughts I'm having are the CPU or motherboard but everything is pretty new. PSU I think is adequate for what I have or maybe not?

Happened with old UEFI and the new one I just updated to.

All drivers up to date.

Nothing overclocked.

Which is why I think it's hardware 100%

How long has this been going on? Since you got your PC together or has it started after a certain update/install of some kind? CPUs being bad, especially with yours at stock would be pretty rare. However, doing a bit more reading, it seems to be a common problem for some people w/ a 9590, here's a link http://rog.asus.com/forum/showthread.php?48794-Problems-stabilizing-FX-9590-on-Crosshair-V-Formula-Z&p=414977&viewfull=1#post414977 If you look at some quick google searches, you'll find folks in a similar situtation. Looks like freezing, ect. happens for others as well due to the turbo speed voltage being to much to handle as these chips are on the very edge of what the FX series can do. It could be that the voltage demands from these speeds are changing to quickly for your PSU to handle, though that's just a shot in the dark I'm thinking of. Only way to tell would be with another PSU that someone is using with your same motherboard/CPU that isn't having problems.

So actually I think you may be right. After doing a lot of reading it seems the chips themselves aren't the greatest and a lot of people have had problems even using larger psu's than mine.

My research is pointing simply to the chip itself rather than the psu. People have had success changing the voltages higher some have had to underclock the chip for stability. I guess at this point I'll mess around in the bios and see if I can get stability. I'd hate to disable a core for functionality.

Yeah, that sucks if you'll have to do that. I would try underclocking by lowering the CPU core speed multiplier by 1 only to see if any change in stability while leaving all 8 cores, voltage, ect. alone. If one doesn't help, try lowering by 2 and so on. If you lower by 4 or something like that with no change, I think the problem will be elsewhere. If however it does fix it, you'll have to decide on sticking w/ a lower speed, raising back to stock speed and add voltage, or getting an RMA and trying you luck w/ another CPU.

Not 100% sure if it's fixed as I've been working all weekend and haven't had too much time but I did get a chance this morning to play around with the voltages. I was able to get Prime95 to run past 30 seconds until I stopped it myself at about 5 minutes. I plan on running it overnight to see if I can get it to still be functional in the morning.

If so, I'm pretty sure that'll also fix the issues with the freezing while under heavy load with media and gaming.

I think you nailed it on the head, Liquid. It was most probably the CPU. Lucky for me I didn't have to underclock.

I'll report back tomorrow and post my final results. Hopefully it can help out some others as well.

Hi pappagiino,

I have the same problem with you. The only thing we're in common is we're using the same motherboard. At the beginning I thought the problem is cause by PSU, but after I replace my PSU, the problem is still existing. Now I'm thinking of the motherboard. But after viewing comments here, I thought it might due to my cpu also. I'm using FX-6300. Please update your final result, that would really help. Thanks!

I thought I had it fixed when I was able to have Prime95 run for more than 30 seconds. What ended up happening, was at about the 10 minute mark, it froze up.

Changing the voltages has helped a little and allowed the computer to not freeze as of late but it's not 100% fixed. I unfortunately don't have the time nor the knowledge to tinker around in the BIOS too much. But I would assume the info that liquidpc posted should help to guide you in a better direction than me.

Hey, I'm here to update my testing. I used Prime95 for more than 30 mins, no freezing happened, so I stopped testing, suppose nothing wrong with the CPU. I also tested fixing the voltage of CPU, disabled cores, but freezing still happened. The weirdest part was, I unplugged front panel USB 2 and USB 3 ports from the motherboard, but when I plugged thumb drive in to front panel USB ports, there was still a chance the computer get frozen. Really don't know why. Can anyone help me!?

Is your RAM running at the specified timings/voltage in BIOS? You may want to check to make sure it's getting enough voltage, even if no other manual adjustments were made. Even though you changed the RAM, have you tried running a bootable version of memtest86+ ? Also, have either of you done a clean install of Windows? Maybe try disabling AMD's version of speedstep, which should force the CPU to run at a constant speed/voltage. Maybe the changes in these are causing instability somehow and the power delivery isn't keeping up somehow, though this would seem like a shot in the dark. I think you may want to disable Cool n Quiet, but i'm not 100% if that's the setting in the BIOS or not. Only have 1 system running AMD at the moment (it's an APU), and i've never had to really mess with BIOS.
