    Ok, no sign of any problem so far, now try the PSU tab.

    Although the memory has also been tested you could also run the CPU: LINPAK test which will stress the memory.

    After the PSU test, rename the results file so the logs stay seperated.

    The only thing I am seeing in these results is the CPU temp is going way over its maximum recommended temperature. The CPU specs state 60ºC as the max, the logs show it is hitting 80ºC. This could be a poor sensor reading but you should check the CPU cooler is properly seated, the thermal paste is covering the entire surface of the CPU and the fan is running well. As the logs show no errors I suspect the temperature sensor is giving a false reading as it should be cutting out at temperatures above 60ºC. In addition, this would not explain the freezes when the PC is idle/sleeping as the CPU will no doubt be a lot cooler during that period.

    Just to update the present state of the PC, is it only freezing when coming out of sleep or does the problem occur at other times.

    Its now mostly when its coming out of sleep, Ive only gotten it to freeze up once or twice after loading windows.

    Ok, I think we have pretty much proved all the hardware is ok.

    Try changing this setting and see if that helps stop the crash on awake problem.

    1. Click Start, Control Panel, Power Options.
    2. Click Change Plan Settings on the Balanced (recommended).
    3. Click Change Advanced Power Settings.
    4. Click on the + next to Hard Disk and then the + next to Turn off Hard Disc after.
    5. Click on the blue writing X Minutes and set the time period to 0
    6. Click on Apply > OK and close all the windows.

    Let it go to sleep and see what happens on awake.

    What happens if you try to start in Safe Mode?
  9. PsychoDave TechSpot Enthusiast Posts: 110

    Doesnt look like you can put it to sleep in safe mode, just turn off the display.

    Edit - Let the computer sit for a few hours in safe mode, messed with it for a little bit, no freezing but it never went into sleep. Took it out of safe mode and as soon as it went to sleep and I woke it...frozen.

    Try the suggestions in the second post in this thread: System hang on awake

    If that does not work: Make sure that your BIOS is set to S3 Sleep Mode in Power settings it may be set to S1 & S3 which could cause a problem.

    If that doesn't work then try selective startup to see if there is a particular process or service that is causing the problem.
    If the problem stops with all the services and processes stopped then re-enable the services or the processes and test again. This will quickly establish if it is a service or process that is causing the problem.
    You can then re-enable the entries in groups rather than one at a time to save time and quickly track down which entry is causing the problem.

    Tried the suggestions in the linked thread and no luck... The BIOS Sleep Mode is set to S3 and no change. So im going to try the selective start up now. Ill post results when im finished

    This sounds to me like a possible CPU or Motherboard issue, because you can't really blame graphics for sound issues, and the HD checked out fine. I'm going to go ahead and say that you should try to swap your motherboard if possible, and see if that fixes it. Motherboard issues are hard to diagnose because they have symptoms similar to other issues, such as PSU failure, but this one seems like a motherboard issue. My motherboard is 4 years old and I'm seeing this issue occasionally as well, and I have a brand new Phenom II x4 840 CPU. I'm hoping it's the motherboard's old age, because I need a new one soon anyway.
