Windows 7: win 7 pro 64 bit several BSOD in the past two weeks unable to solve

Windows 7 pro 32bit
win 7 pro 64 bit several BSOD in the past two weeks unable to solve

New Lenovo thinkcentre M73 model 10B6001SUS, OEM install win7pro 64bit sp1 (pre-installed by manf),
8gb ram (2 x 4gb ea)
I've tested the RAM using memtest86+ v5.01 no errors. Windows list the 8gb.
RAM Crucial one CT51264BD160BJ.C8F the other CT51264BA160B.C16F
BIOS version FCKT73AUS
Boot Block Revision Level 1.73
I've updated the NIC driver to the latest realtek driver. Windows updates list last one was installed and only 1 optional one not installed.

I've uninstall Norton and I'm using AVG Free 64bit build 16.81.7639, nothing found. Checked for root kits.

I've attached a copy of the DM log & the minidump folder

Not sure what is the root cause, nor how to read the logs

Thanks for any guidance you can give.

Welcome to the forum,

Did you put the Crucial RAM in? Your earlier dumps show one Crucial and one Samsung module.

Your last dump does show both Crucial though. Are they a matched set? I get different results searching the part numbers.

Did you run Memtest86+ for 8 passes? That is the definitive test length.

Your last dump is flagging AVG,

Unable to load image \SystemRoot\system32\DRIVERS\avgidsdrivera.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for avgidsdrivera.sys
*** ERROR: Module load completed but symbols could not be loaded for avgidsdrivera.sys
You can try uninstalling that for now and just use MSE for the time being, to see how it acts.

Someone else might come along with more info, that's just what I saw.

Windows 7 pro 32bit

I did install the Crucial RAM, system came with one Samsung 4gb and order another 4gb with the system. Thought the issue could be RAM not matching so ordered another Crucial 4gb to match but when it arrived it was not the same model. I have ordered one Kingston 8gb KCP316ND8/8, didn't want to end up with another miss match. But it won't arrive until next week.

As for the memtest I believe each test was 10 passes, I let it run until it was listed as completed. I tested each 4gb alone and then with both installed.

I've been using AVG Free on several systems Vista, XP, win 7, win 8 and even win 10 most have been 32bit, at least 4 others have been 64bit, this is the first BSOD.

I'll give MSE a try, but my pass experience with MSE didn't seem to perform as well as AVG.
Thanks for the suggestion.

BSOD For The Past Few Weeks - No Apparent Pattern
I've gotten BSOD for the past few weeks. At first I thought it was due to the drivers for my graphics card, but I wiped the drivers clean and installed an older version to no avail. I still get BSOD every now and then. There's no apparent pattern - at least none that I can see. Sometimes it happens...
