Screen Stutter and Sound
Basically I put together a new system yesterday. All went well, as aposed to a previous system I built which had a D.O.A psu and HD. I thought it was all running sweet until I started gaming later on.

After around 20-30 minutes of playing League of Legends or World of Warcraft or Call of Duty 4 or Brink (so basically any game) my game will start to lag and stutter, the sound will also stutter to. On my voice comms people talking will also cut out and repeat. I move forward on the game and I don't see the movement but after 1-2 seconds I appear where I wanted to move to. With the sound the game sound also stutter i.e. League of Legends normally would say "You have killed an enemy" but when I'm stuttering becomes "You ou ou have killed an an enemy my my" or to that effect.

This is really confusing me because I'm running core temp and it shows temps @ around 60 on the cpu. My gpu around 50-60. I have a gadget on my windows 7 which displays the cores of my Cpu and their activity and usage. I notice on this gadget that maybe 1 of my core peaks at around 80-90% usage (usually the second core) but then it drops back down to the average 50-60% usage like the other cores. I also have a memory gadget which shows the usuage of the memory and that stays normal, doesnt really move from around 30-40% usuage or a little more depending on game. The last gadget is the GPU one and that displays a normal usage of the GPU, a good average temp and no spiked usage. I also have Hard Disk Sentinal because I thought the HD was quite loud but after research found out the HD is actually loud. The Hard Disk Sentinal shows the HD is perfect.

The system is;

Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor

Asus P8P67 LE Intel P67 (Socket 1155) DDR3 Motherboard B3 Revision

Corsair Vengeance Blue 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit

MSI GeForce GTX 460 HAWK "Super-OC" 1024MB GDDR5 PCI-Express Graphics Card

Western Digital Caviar Black 750GB SATA 6Gb/s 64MB Cache

Corsair Enthusiast Series TX 650W V2 High Performance '80 Plus Bronze' Power Supply

Im running windows 7 x64 aswell.

Anyone know of this issue or anything similar? Any help is appriciated


*Edit*
I've flashed and updated my Bios. I updated the onboard Audio drivers and updated to the latest nvidea drivers when I first had the issue.

*Edit* I have now also disabled the onboard sound and put in my Sound Blaster sound card. When the stutter/lag happens now the sound remains fine, doesnt break up like it did before. But the lag/stuttering is still happening.

*Edit* When this happens I notice that the cpu has picked up to 80degrees and that 1 of the cores will go to around 80% usuage while the others remain low, this usuage usually swaps between core 1 and core 2.

Is 80 degrees going to cause this? if so should i get a new heat sync? the case im using is a Coolermaster Silencio
 
80 degrees Celsius is way too high, check that you applied thermal paste and only used a small amount (Size of a pea/grain of rice)

If you mean 80 degrees Fahrenheit, you should be fine.

It is celcius, heres a screenshot basically of what happens when i lag. You can basically see the 1 core @ 91% usuage I think. The temps are in the bottom right on my toolbar.
Could this be a psu problem aswell as a cooling problem? is the psu (650w) enough to power this system? it isn't over clocked or anything, all standard.

It seems as if the CPU is getting too hot and therefore cannot cope as well. Have you overclocked it at all?

As for one core having more usage than the other, does this happen when you are playing your games, or when it is just idling or doing other things? If it is when you are gaming, it is most probably being caused because the game cannot make use of all 4 cores. Either that, or the CPU is not seated correctly. Try reseating the CPU and see if that solves your problem. You will have to reapply thermal paste however.
 
No its not overclocked at all, its all standard. Standard heat sync, standard case cooling etc. I will give reseting the processor a go. It's basically the thermal paste intel put onto the heat sync, i didn't apply any. Need to find some remover and my arctic thermal paste
 
Are you using the stock cooler? If so, then those temperatures are fine for idle; it is the load temperatures that you need to keep an eye on.
 
Coolermaster Silencio

"Silent" cases trap more heat. Intel's stock cooler is the bare minimum required to dissipate the CPU's thermal signature, which relies on sufficient airflow through the case to stay within spec.

It seems to be doing alright, albeit a tad toasty. Pushing more air through and out of the case should help, which means better or more fans, and picking up a decent HSF wouldn't hurt either.
 
Changed the thermal paste and now it sits around at 30-40 idoling and 50-60 in game. I played a COD game earlier and it was fine all game, came out of game and spoke on teamspeak for a while and all of a sudden my mouse cursor became slow, increased my dpi from 3200 to 6000 and it was still insanely slow. People on teamspeak were saying i was lagging when i spoke and the computers responce time increased.

I'm so lost with this

Have you tried running the pc with the side panel off and directing more airflow over the motherboard, could help if it is an overheating problem.
 
Sorry only just got back from a friends bday trip.

But, I don't think its an overheating problem. I've just been sitting on mumble (voice comms like vent) and after just sitting here for 30 mins the people im speakin to start breaking up, my mouse cursor becomes very slow, i usually have my mouse at 3200dpi and i zoom around my screen but now i have to cover my whole mousematt to get across the screen.

Seriously lost. Any ideas? Should i download some memory test for a memory leak? but wouldnt a memory leak happen instantly from starting my system up? Could it be a problem with my OS? its not an original copy of windows 7 ultimate (sorry :( student money is terrible). I can actually get an original copy if needed but I'm just lost when it comes to this problem...

Someone also mentioned it being Asus settings on the mobo bios, some energy saving settings maybe but I don't see any energy saving settings...


P.s. have the side panel off...
 
So I did a memory test and it passed, I also don't notice anything in task manager about memory sky rocketing when this problem happens...so that rules out it being my memory. So basically whats left, HD? OS? Gfx card? and Mobo?

When I first put the computer together I saw the Sata 6G connections so I thought "Oh might use those if it gives quicker data transfer" but this morning I decided to just move the sata's to the normal ones. Upon doing that when I boot up it says "No Hard Disk Detected" but it still boots windows 7... find that quite weird?

anyways I took some photos of my bios and of the voltages... hopefully will help.
