Hi, I've had this problem for a while now, and only just starting to get annoyed enough to try and fix it. What happens is about once a day the sound on the computer stutters and then the entire thing freezes up. The screen stops moving and I have no control. The program I have running on my G510 screen stops working too, so its not just the screen freezing. Because I can't do anything I have to hard restart it by holding down the power button and then turning it back on. I first thought it was a virus of something so I ran as many virus searches as I could, but that didn't fix the problem. Then I tried updating every driver I could find, but that didn't help the problem either. Finally I thought it would be a problem with the RAM so I ran memtest 86 over night and it said that there was one error. Ok, so theres something wrong with the RAM. next I tried taking one stick out that I thought might be the bad one and ran the memtest overnight again. It said there wasn't any problems so I figured the other stick was the bad one. Last night I ran the memtest with the other stick of ram and again it said there wasn't a problem. Now I don't know what to do because I don't know if there was a problem with the way I ran the memtest or if there is something else wrong with my computer. Thanks for any help that you can give.

Usually when one RAM stick is faulty it gets way more errors than only 1, I'd run memtest again with both sticks to see if it finds that 1 error again, if so, since individually they don't report any issue it could be a problem regarding Dual channel mode, try setting the command rate to "2T" and test them again.

Another device that could cause the symptoms you describe is the HDD, run a chkdsk /R on all your partitions, it will take some hours but it should find any problem in your HDD.

Ok, I ran chkdsk on both of my hard-drives and it didn't give any errors. I also ran memtest overnight with both sticks in but it didn't give any errors. It only got through 4 passes, but I ran it for nine hours so I don't know if it wasn't long enough or something.
 
4 passes are enough, seems to me that 1st report was a false result (like I said earlier, usually a faulty ram gives hundreds of errors).

This freezing / sound stuttering happens with a specific application? always under heavy load (running CPU and/or GPU intensive application) or does it happen randomly even at idle?

Check your temps and if possible run some software to log your temps/voltages so we can see what's going on when the problem arises.
 
48ºC is kinda high for idle (at least for CPU), makes me wonder how the airflow in your case is, there's a chance that your PCH chipset is getting too hot, that could lead to random crashes even on idle.

See if HWMonitor or AIDA64 can get a read of your PCH temp, unfortunately some mobos won't give a read about it, you could also check on BIOS if AIDA64 etc can't get a read of it.

Other than that, perhaps it's time to test the CPU, try running prime95 overnight with the small FFTs option selected.

Ok, so there's three temperatures under ITE IT8720F which I think is the PCH temp because I can't find anything labeled PCH in HWiNFO or any of the other temp programs. They are 44, 55, and 46.
 
if PCH is at 44-46 under load or even at idle it's ok, however if it's at 55, specially at idle that's a potential problem, any chance two of those temps are from your HDDs? see if you can narrow down to what those temps belong, maybe using another temp program or looking at bios what components are close to those temps.

I ran the prime95 for an hour and I didn't have any problems. I'm a little afraid to run it overnight though because the temperature was 68 for the whole test. I don't know how to find the PCH temperature because none of the temperature monitoring programs I've found has had a line for PCH, and all the googling I've done doesn't help find it either. Here's the log from AIDA64 while prime95 was running: Sensor Properties:

ahhh kinda false alarm...

when you wrote:

"Ok, so there's three temperatures under ITE IT8720F which I think is the PCH temp because I can't find anything labeled PCH in HWiNFO or any of the other temp programs. They are 44, 55, and 46."

You meant this lines right? (from the latest readings ofc)

"Debug Info T 47 57 49"

47 being mobo sensor, 57 being your CPU and 49 your CPU Cores.

However we still don't have the PCH temp, we're fishing at this point so if you don't have a side fan to blow air into the mobo (so it lowers the PCH temp) try adding one and see if that solves the problem.

Beyond that....... you could check your PSU voltages just to continue our verification of your pc components.
