    I've had this pc for nearly 2 years now, and this is just recently happening. Idle temp is around 40C at the moment. However after 10-15 minutes of playing certain games, GTA IV being one of them, the cpu will reach a certain temp (52C) and shut down. I've read many threads on the subject, nothing has explained why it's happening. I keep the dust out, everything is seated properly and arctic silver is on the chip. I have an aftermarket heatsink/fan as well. I used to be able to play any game that would run, it never overheated like this. Hope someone can help. I've included a CPU-Z report.

    Also I realize I posted this in the wrong forum. Could someone move it for me? Don't know how to delete it.

    The operating system is ?
    The pc manufacturer is ?
    The model is ?
    The amount of ram is ?

    By shutdown, what do you mean? Does the computer turn off, Blue Screen of Death, Freeze, or ?

    The cpu turns the computer off at 52 degrees to protect it from damage.

    All info about my pc is in the text file I think.

    Must run, but a couple of thoughts:
    1. 52 is a very low temp to truly shut the cpu down.
    2. The normal thing is that cpu clock is reduced to 1/2 of normal when a certain temp is reached. some will have still another step of further reducing clock before shutting down clock to zero.

    That being said, what happens if you simply take the case off of the unit and blow a floor or desk fan directly at the unit?

    Download, install, run CoreTemp for temp monitoring.

    Thanks for the advice so far and sorry for taking a while to reply. I tried playing some games with the case open and fan pointed at the processor. No luck, it ran hotter if anything. My case has several fans and has good air flow actually.

    I use speedfan for temp monitoring, I assume it's accurate but idk.

    Also I agree 52C is pretty low for the cpu to turn off the computer, I hear about other cpus overheating at 80-90C. It's not exactly like a setting I can change though.

    Again, thanks for the reply and advice so far, any other ideas on why it's suddenly overheating? Kinda frustrating not being able to play certain games.

    Is your cpu included in the documentation provided in the last link I gave?

    Would you humor me and, as an experiment, not use SpeedFan bur rather use CoreTemp (the link for coretemp is in my previous post).

    Let me know what CoreTemp reports.

    I didn't see any amds listed in the max temp link.

    Thanks for suggesting Core Temp, great program.

    I've included a log from core temp, playing gta iv until the pc shut off. Hope it helps diagnose what's going wrong here.

    There is the distinct possibility that your lockup is coming from another source.

    To make separating the wheat from the chaff, use the procedure I include to clear out your event logs.

    After the computer hangs and you reboot, then look in Event Viewer at the Critical errors (they are the red flagged ones). Be sure to wait for EventViewer to populate.

    Now let's see if I can find those writeups.

    CLEAR EVENT LOGS


    To delete those event logs, you can:
    Ø Copy and Paste following into Notepad.
    Ø Save as ClrEventLogs.BAT (or another name but extension must be BAT)
    Ø Navigate to ClrEventLogs.BAT using Windows Explorer
    Ø Right-click on ClrEventLogs.BAT
    Ø Click on Run as Administrator


    @echo off
    FOR /F "tokens=1,2*" %%V IN ('bcdedit') DO SET adminTest=%%V
    IF (%adminTest%)==(Access) goto noAdmin
    for /F "tokens=*" %%G in ('wevtutil.exe el') DO (call :do_clear "%%G")
    echo.
    echo goto theEnd
    :do_clear
    echo clearing %1
    wevtutil.exe cl %1
    goto :eof
    :noAdmin
    Exit

    ===========================



    Oh yes, for event viewer run eventvwr.msc

    Should've looked at the event viewer earlier. I suspected that it might not be the cpu that was overheating. Found this under system events:

    System shutdown due to graphics card overheating


    There are a lot of these errors. One thing that happened not too long ago: was cleaning dust out of the graphics card, and one of the screws holding the fan on it broke (quite easily for some reason). As a result it doesn't fit on there as tight. Anyway let me know what you think.

    I would suggest turning the unit off.

    Gently cleaning the dust out. One way of doing this is with a vacuum cleaner set on a low suction setting. Another way, is to buy a can of compressed air and blow out the dust that way, being sure to first let all of the water condensate in the compressed air to blow out into free space.

    Carefully examine the graphic card fan. Replace any missing screws.

    Turn the unit on, with the cover off.

    Watch and listen. Is fan working well?

    I had just cleaned everything out with compressed air recently, but I finished the can off on the gpu. Still some dust left, so I used a soft cotton pipe cleaner to get the rest, especially in the fan. My room is quite dusty, so I have to be diligent cleaning out all the nooks and crannies of the gpu/cpu fans so the dust doesn't build up.

    The screws that are used to hold the fan on are a bit odd. If you try and use a phillips head screwdriver to turn the screws, they tend to break apart very easily. I broke one apart trying to remove the fan to clean it a couple months ago, now I'm hesitant to mess with it further. Not that I would know where to find a replacement screw for it, those parts aren't common and are specific to the gpu afaik. Also the fan doesn't appear to have loosened significantly, not sure why that would explain the overheating. I think the problem goes back before that time in any case. The fan works fine as far as I can tell. I suppose if it's loose by a slight margin, maybe the fan won't work as efficiently, I really don't know.

    Here is an excerpt from a log from a gpu utility showing temp and fan speed while gaming. Obviously it's overheating, just not sure why. Starting to think it's been damaged from running games that are graphically intensive over the last 2 years. If it had 1gb memory as opposed to 500mb, maybe it wouldn't be under such heavy load. I should probably start saving up for a new card.

    Increasing the amount of ram would be good. Maybe a graphics card replacement is in order.

    Alright well I'm not too happy with the outcome, but in any case thanks for the help. Being that the gpu has been overheating at 237F, shouldn't come as a surprise. Think I've ruled out doing anything to improve performance of the video card (other than replacement or maybe crossfiring), as well as anything being wrong with the processor. Think you can consider this solved.
