BSOD at random intervals, no specific pattern even after clean install

    To verify RAM is bad you'll need to test each stick in each slot to rule out a bad board. 7 passes each time unless you have even one error, you can stop and go on.

    Agree with Britton30, when you get errors with all RAM cards installed you need to run memtest86+ on one RAM card at a time, follow the procedure in the tutorial linked previously. You can stop the test if you get any errors, one is too many.

    Sometimes RAM errors can be stopped by making some BIOS adjustments.

    Can you download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

    Go to your BIOS and tell us what the CPU, RAM and the CPU integrated memory controller voltages are.

    Use Real Temp , to check the CPU temps when at idle, under load and/or testing.
    Let us know the minimum and maximum temps you get.

    From your System Event Logs:
    This usually indicates the CPU is overheating.
    When was the last time you re-applied the CPU thermal paste?

    Right. I removed the old RAM and I had no BSODs in two whole days! But now it's back to its old tricks. Very annoying.

    Here are the screenshots, bearing in mind that they only feature the two identical newer RAM:

    Attachment 242122
    Attachment 242123
    Attachment 242124
    Attachment 242125

    CPU min was 38 and max was 49.

    I could only find my Vcore in my BIOS and not the others but that's at 1.21V.

    New heatsink and paste applied in July of this year. I've also attached dump files, too.

    What were the memtest results testing one at a time in all slots?

    I have not yet done that. I hope to do it later today.

    Your motherboard has 7 BIOS updates since your 0601 version.
    Update your BIOS to v1401.

    BIOS > Advanced > JumperFree Configuration > Voltage Control
    DRAM voltage
    NB Chipset voltage

    Let us know how the memtest86+ went on each RAM card.

    Many thanks for this.

    I updated my BIOS with the ASUS Updater software but now my PC won't boot. Even when I put in my Windows DVD and change the Boot Priority to use the disk drive it just won't boot and keeps on asking to insert boot CD. I can access the BIOS screen fine but Windows doesn't want to load.

    I couldn't get MemTest to work prior to BIOS update, either, but haven't tried running it since - mainly because I'm slightly concerned that updating my BIOS seems to have left me locked out of Windows.

    Try downloading the BIOS file again and re-flashing it. Sometimes a file will be corrupted in a download. Use what ever tool they have for flashing within BIOS, not from w7 if possible.

    Easier said than done. USB doesn't seem to work, I don't have a floppy drive and I cannot get into Windows...

    Not sure if there's a way I can currently update my BIOS. But the file was from the ASUS website and the BIOS is showing it as the latest version.

    Right. Managed to update using USB, finally. Restarted and Windows still does not boot.
