Random BSODs in brand new build

Hello. Just put together new HTPC and it is randomly crashing.

OS: Windows 7 64-bit, OEM Retail
Processor: AMD A8-3850
Graphics: Onboard
MOBO: ASRock A75M-ITX
Memory: Mushkin Silverline 8GB (2x4)
HD: Western Digital Caviar Black 1 TB (WD1002FAEX)
Blu-Ray/DVD: Lite-On internal (IHES112-04)

--------------------
It has crashed several times in 2 days. Crashed when clicking the "start" logo. Crashed in internet explorer. Crashed in google chrome. Crashed in XBMC program. Crashed all by itself from desktop.

Right before the screen goes blank, before the BSOD pops up-- the graphics are all messed up. Horizontal lines of jibberish for 1 second, then the crash. Computer temps are at 20 C. Memory has been tested overnight (12 hours) with Memtest and 0 failures.

I don't know what I'm looking for here. Any help?

I attached the .zip from the SF Diagnostic Tool.

Code:

BugCheck 109, {a3a039d898996529, b3b7465eeb16347f, fffff80002071af0, 1}

*** WARNING: Unable to verify timestamp for win32k.sys
*** ERROR: Module load completed but symbols could not be loaded for win32k.sys
Probably caused by : memory_corruption

Code:

Usual causes:  Device driver, Breakpoint set with no debugger attached, Hardware (Memory in particular)

memory_corruption doesn't necessary mean that a RAM module is faulty, it can also point to a object which corrupted the RAM at the time of the crash, for instance a corrupted driver or program. Paging files and the CPU caches can also be causes.

Follow these steps -

Test for any corrupted drivers, by running Driver Verifier for least 24 hours, stop the test if a BSOD occurs before this time frame. Driver Verifier will place stress on the drivers within your system, which will cause corrupted drivers to crash and hopefully be pinpointed.

• Driver Verifier - Enable and Disable

Memory:

• RAM - Test with Memtest86+

Run Memtest86+ for least 9-10 passes, and preferably overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Test each RAM stick and every motherboard DIMM slot available.

Remove avast! (at least to test):

Code:

Start Menu\Programs\avast! Free Antivirus

Use the official uninstaller:

• avast! Uninstall Utility | Download aswClear for avast! Removal

Install and perform full scans with:

• Malwarebytes : Free anti-malware download
• Microsoft Security Essentials | Protect against viruses, spyware, and other malware

Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system.

Please upload a SystemInfo.txt file, use may use the same SF tool as used for the .dmp files, but make sure you select "Grab All".
