    Under the normal stability test the GPU test for 12V should be in the folder - any fluctuation would indicate a failing PSU (or graphics power circuit).

    I would strongly advise NOT to use the power supply test. OCCT can actually kill a perfectly good PSU on occasion.

    Your best bet would be to have the power supply tested. If there is any abnormality with the 12V rail, then get ready to contact your etailer/retailer/Corsair for a warranty claim.

    I did the GPU test but the graph doesn't show the Vcore still. Only FPS and temperature.

    Wow Asus Smartdoctor didn't save my underclock settings on my GPU. MSI afterburner did and things have been running fine so far.

    Under/Over clocking is not my forte, for that DBZ is the best to shed some light on this. But I think by underclocking you are also reducing the power requirements of the graphic card, hence, lot less stress on PSU as well. Anyway as I said I'd rather leave the explanation with DBZ.

    Yup.
    Core and memory frequency have a direct bearing on power consumption. Lower the clock rate on either, or both, and power consumption drops off accordingly.

    While you may have found a solution - it will only be temporary. Failing power supplies (and graphics cards, RAM, harddrives etc) never get better of their own accord.
    I would suggest you back up frequently. If the PSU is unstable, then it can have a flow on effect -noteably RAM and HDD's which are very sensitive to power ripple (fluctuations in voltage).

    Well I do have a 5 year warranty so if my computer starts acting up again, I'll just return it for a new one.

    Well it happened again. I don't know anywhere I can test my power supply to confirm that its the problem so I guess RMA is my best bet.

    Any qualified electrician should be able to check the PSU...failing that, put out an APB for a computer tech with a multimeter...or maybe just invest in a PSU tester -which might be cheaper than taking it into an electronics shop.

    You could also just RMA and see what happens- worst case scenario, you're out shipping charges - might not be insignificant given the weight of a PSU.

    Well, I'm waiting for the RMA number from Corsair but what if the PSU isn't the problem? What other things can cause this?

    DBZ pretty much summarized it in his post # 30. Next suspect could be graphics card IMO, but anyway will wait with PSU replacement and see what happens.

    I agree with Archean, and DBZ in their assessment of the PSU. It sounds very much like the 12v rail is becoming unstable once it starts hitting higher amps during gaming, or when simulated by testing.

    That being said, you need to look more closely at the cause of those CPU temps as well. I would highly recommend a replacement aftermarket cooler, and some thermal paste (most decent coolers come with good paste added to the heatsink or supplied in the box) as the temps your experiencing are very high.

    I generally prefer to see temps at or below 60'C on a stock system, and not much higher if your overclocking. Keeping temps below the threshold prevents CPU errors brought on by throttling due to overheating, and is of benefit to the CPU long term. You want it to be as cool as possible.

    Its also worth noting that your i7 2600K has a max Tcase temp of 72.6'C. Meaning internally the CPU could be as much as 10'C hotter than the case (metal case the heatsink fits onto) itself. You want to avoid hitting 70'C in any case, simulated or not as you will be very close to experiencing thermal throttling of the CPU due to heat, which in itself will make the system unstable the majority of the time.

    I've refitted the heatsink with new thermal paste and now my CPU max temps are usually 55C-60C. Thanks for the help guys, I'm sending out the PSU today.

    Alright, the PSU came and I've played Metro 2033 for a good 40 mins to an hour with no restarts.

    My computer restarted again...I was playing Deus Ex HR for an hour and 30 mins, then it restarted. I was checking temps, 55C CPU and my GPU was like 68C. I did Memtest86 just to make sure it isn't the RAM and it still hasn't shown any problems. I'm going to do the CPU and GPU stress tests again.

    My computer restarted after 15 mins of the CPU test. I don't think its overheating because Realtemp said the CPU was only 55C. So I guess something is wrong with the CPU. Does this mean the CPU chip itself is faulty, or something with the motherboard?

    The GPU stress test finished with no errors. Tho it was kinda weird because my GPU would go up to 78C and once it hit 79C, the fan would kick in and would stop when the GPU became 72C and it would repeat again.

    Does anyone have an idea of what the problem could be? It can't be the PSU because I just RMA'd it, can't be RAM because Memtest86 show no errors, and I haven't heard a CPU processor being faulty like this.

    So I'm guessing video card or motherboard? Tho that's what I'm thinking and I'm not really good with this stuff.

    Anyone have any idea what the problem could be? I guess I'll call ASUS tech support tomorrow about the problem and if it could be the card or motherboard.

    Here's the OCCT GPU stress test. On top, it says that my CPU is overclocked to 3666.77 Mhz but I never overclocked.

    Hey guys, sorry for posting so much but I'm trying to fix this problem. I disabled Auto Restart so I could see if I get a BSOD or not and I also removed one stick of RAM so I could test the RAM. While playing, my computer just froze, and I had to manually shut down the computer. Then, the computer wouldn't start up again. Instead, a LED near the RAM labeled "DDRRAM MemOK" would just stay on. I switched RAM sticks and it still wouldn't start up. I put the RAM sticks in ports 2 and 4 instead of 1 and 3 and the computer still wouldn't start up. I put one stick of RAM in port 2 and that didn't work either.

    I thought it was the RAM so I took out RAM from another computer, put it in ports 1 and 3, and the computer did the same thing. Put it in ports 2 and 4 and it still didn't work. I know it can't be the RAM because they are both DDR3 RAM and it worked fine on the other computer. Could it be the motherboard RAM slots that are causing the problem?

    hmmmm could possibly be the motherboard as i have seen them go bad long before a cpu would imo rma the motherboard and see what happens can't hurt as the problems are already bad.

    Will do. Is it possible to RMA a motherboard without the plastic cap that covers the CPU slot? I can't find it anywhere and I've heard you need it in order to be able to RMA.

    i wouldn't think you would need that you will just have to call asus and find out.

    I know its been 2 years but I thought I should post my solution in case anyone reads this and needs a solution. I figured out that my RAM timings were wrong and that caused restarts. It was 11-11-11-28-1 when the ram manufacturers say to put it at 9-9-9-24-2. Fixed the timings (enabled XMP settings which had the correct ram timings for me) and no restarts ever since. If anyone has a similar problem then check your ram timings to see if they match the manufacturer settings.
