Windows 7: Different BSOD randomly, w/ and w/o overclocking, Memtest86+ passes

Different BSOD randomly, w/ and w/o overclocking, Memtest86+ passes

There seems to be no pattern as to when I get a BSOD. I ran Memtest86+ for about 18 hours (8 full cycles) and there were no errors. I've noticed also that anytime I run Prime95 with high FFT lengths, all 4 cores fail almost immediately ("Rounding was 0.5, expected 0.4" is a common one). I have gotten BSOD's when nothing was overclocked. I've gotten it when doing light overclock stress testing as well. I've gotten it when doing no stress testing and nothing else that's CPU or memory intensive.

Attached are the results of prefmon /report and the files from running "BSOD Dump & System File Collection". I'm really at a lose now of how to proceed. Except for a couple spare HDD's that have been working fine for months, this entire PC is new.

Specs:
Windows 7 x64 Ultimate SP1, all updates installed
Intel Core i5 3570K
Corsair Vengeance Blue 16 GB DDR3 SDRAM Dual Channel Memory
OCZ ModXStream Pro 500W Modular High-Performance Power Supply
Crucial 128 GB m4 2.5-Inch Solid State Drive
GIGABYTE GA-Z77X-UD5H LGA 1155 Intel Z77 M/B
COOLER MASTER Hyper 212 EVO CPU Cooler

Thank you in advance!

Your crashes indicate hard disk or SSD problems. Since you are using an SSD, make sure the following are up to date:
  • Your SSD Firmware
  • Your BIOS Version
  • Your chipset drivers
  • Your SATA controller drivers

If the above are up to date and you are still having problems, proceed to the next steps.
  • If you are overclocking any hardware, please stop.

  • Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log.
    For any drives that do not give the message:
    Windows has checked the file system and found no problems
    run disk check again as above. In other words, if it says:
    Windows has made corrections to the file system
    after running the disk check, run the disk check again.

  • Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

  • Download and install Malwarebytes, update it, do not start the free trial, and then run a full scan. Also run a full scan with your antivirus software installed on your system. If you do not have antivirus software installed, see the Good and Free system security combination. for better security steps and scanning tools. Make sure to update the security software before running the full scan.

  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
    warning   Warning
    Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
    Once these steps have been followed, it is safe to remove and replace components within your computer.
