FX-6300 freezing under load

[godlike lgn]

So, I've got a PC with the following specs:

 

AMD Six-core FX-6300 @ 3.5 GHz (Stock)

M5A78L-M LX/BR Motherboard

1x 8GB RAM Corsair Vengeance 

EVGA GTX 650ti
EVGA 500W PSU

 

It simply freezes under high CPU usage. Doesn't turn off tho, so I'm guessing temperatures are not a problem. If I run a CPU stresser (using Core Damager), the PC freezes and there's nothing I can do but restart it. If I try and open several programs at once, it freezes too. Any tips? I'm thinking on just installing a fresh copy of Windows.

What are your temperatures like anyway? Try HardWaremonitor or any program just to double check.

 

If you have time to kill and don't mind doing it a fresh windows install won't hurt.

When I push the usage to around 70%, the temps are not higher than 68ºC. When idle, about 40ºC, running the stock cooler. I really would like to see the temps while the PC is frozen, but then I cannot open my hardware monitor...
I can do a fresh install without a problem, but if there's a fix that does not involve doing that, it would be great

Your temps are high, the FX cpus thermal throttle at 70c and AMD recommends keeping them under 61c.

So I might test an aftermarket cooler... Maybe a Hyper 212 EVO will do the job.

I have a FX-6300 clocked at 4.2GHz on the stock cooler.  I've been able to stress the CPU to 100% and have temps go to 79-80C and never have it react like this (though I admit I run Linux so I can't say that it wouldn't under Windows - I dunno).  Your temps are a bit high but shouldn't be.  Can you check in BIOS what your voltage is?

Just hit me why my CPU likely isn't shutting down at 70C - I have the Cool and Quiet shut and other throttling turned off in BIOS.  Regardless - I'm still wondering if your board is running too high of volts causing you to have high temps.

 

Also - it's NEVER a bad idea to add extra cooling.  I would recommend the Cryorig H7.  I'm replacing my stock cooler with it as soon as it gets here.  Great cooling at a great price and zero RAM clearance issues.
