    This happens when I do CPU intensive stuff, such as render video, or play a game. Is it because my CPU is overheating, or PSU not providing enough power?

    My specs

    QX6700 (stock speed)
    600W PSU
    2gb ram
    8800GTX
    6 HDs

    I get 70C temp when it idles. Stock cooler, with ArcticSilver. I got a scythe inifnity, which I still havent installed.

    the intel will throttle so it's not likely that


    whats your mobo? What brand psu? what memory?

    Does it freeze on prime95? memtest86+?

    One thing you can try to do is turn off windows auto-restart.

    Start > Right click My Computer > properties > advanced > startup and recovery settings > Un-click automatically restart.

    Fuck. I just noticed the 70c at idle.

    That's too high. I'd put the better cooler on it right away.

    And when you put the paste back on, make sure you are applying the thinnest layer that you can get in there that covers the whole contact surface.

    I know they say to use a grain of rice sized squirt of the stuff, but fuck that.
    I take the edge of a box cutter razor, and apply the stuff very carefully until
    there is a nice thin coat across the cpu. If it doesn't go perfectly smooth across the cpu surface,
    I'll do it over. You do not want too much in there!

    My E6600 is running at just 32c right now, with a Zalman 7700 copper cooler.

    Its an OCZ gamerxtreme PSU. Wasnt cheap.

    nforce 680i mobo.

    It doesn't freeze, it just shuts off. During rendering, Core Temp shows 95-100C on some cores. I reapplied the grease and reseated the heatsink a few times. No change.

    Keep in mind this is an extreme version of the CPU, so its suppose to run at a higher temp than normal C2D CPUs.

    Yes, it will run hotter, but idle at 70 is dangerous on a high load. It should be idling between 50 and 55 with proper cooling.

    You're running some ridiculous OC, aren't you?

    No, its running stock. I tried OCing, but the temp just becomes ridiculous.

    You said you have a scythe inifnity? You seriously should put that on there.
