Welcome to the forum. Sorry you are having problems. Both dumps reference memory errors.

Error code 1A, MEMORY_MANAGEMENT - Usual causes: Device driver, memory, kernel

Error code 50, PAGE_FAULT_IN_NONPAGED_AREA - Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: ffffe68000001428, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff80002abb4e4, If non-zero, the instruction address which referenced the bad memory
    address.

You are running Avast antivirus and Windows Firewall. Are you also running Windows Defender? If so, please uninstall or disable it. Download and install Microsoft Security Essentials. MSE supersedes Defender and includes the protection of Defender. MSE is compatible with Avast. I found Widows Defender application errors in you error log.

You have one outdated driver loaded on your system.

cpuz_x64.sys Tue Oct 07 15:44:27 2008 - Make sure you have the latest version of CPU -Z installed. CPUID - System & hardware benchmark, monitoring, reporting

Because both dumps reference memory, test your RAM with Memtest. Follow the instructions in this tutorial and run Memetest for a least 7 passes. This will take about 7-8 hours. Errors, if any, will show on your screen in red. Post your results.

RAM - Test with Memtest86+

If Memtest finds not RAM errors, errors, please enable Driver Verifier following the instructions in this tutorial. If Driver Verifier encounters a faulty driver, it will trigger a BSOD. Upload any and all Driver Verifier enabled dumps. Use your computer normally while Driver Verifier is running.

Driver Verifier - Enable and Disable

Please update your System Specs. It helps us help you.

If available, upgrade your Intel G33/G31. Express Chipset Family. Your video driver is old - September 2009.

Also, please run memtest86+
Memtest86+ - Advanced Memory Diagnostic Tool

I completed my initial analysis; please refresh this page.

Looking forward to it. We will be here. Good luck!
