You have some older drivers installed that need your attention
rminiv3.sys 8/18/2007 (way too old) Radmin Mirror Miniport Driver V3
www.radmin.com (uninstall or update)
NuidFltr.sys 5/8/2009 (too old) Filter Driver for Microsoft Hardware HID Non-User Input Data belongs to the software Microsoft IntelliType Pro / IntelliPoint by
Link Removed - Invalid URL nvlddmkm.sys 5/14/2009 (too old) Nvidia Display driver. Determine the exact model of your nvidia hardware and go to
Drivers - Download NVIDIA Drivers and update the driver.
Rt64win7.sys 12/24/2010 (not bad) should be May or June of this year.
Check here and see if your RealTek network interface card is listed. If not determine exact Name, Model Number, Rev. #, and use the RealTek site to get the latest.
RTKVHD64.sys 1/4/2011 (better) but I think there is a
newer one here.
Catch those drivers up as best you can and see if that helps your issues.
Additionally you need to
read this follow the instructions explicitly, including all SPD tab, as well as zipping up the export html report from RAMMon.
Hit your system disk with the Check Disk utility. (Command prompt) type
chkdsk c: /R (answer in the affirmative when prompted to run at next reboot "Y") and reboot. Let it run all five stages.
Additionally
MemTest86 test stick(s) individually as well as slots individually. (At least 7 or 8 passes, I usually do 10).
Keep us posted and welcome to the forums.
