1) Definitely do the AVG removal as shown above and replace with MSE.
2) Update your PowerISO:
SCDEmu SCDEmu.SYS Sun Nov 08 22:27:29 2009
PowerISO - Create, Edit, Compress, Encrypt, Split, Mount, Extract ISO file, ISO/BIN converter, Virtual Drive
3) Install my attachment to update this very old ATK0110 driver:
ASACPI ASACPI.sys Mon Oct 30 22:09:12 2006
4) Update both your keyboard and mouse drivers from Logitech. These drivers are ancient:
LMouFilt LMouFilt.Sys Wed Apr 11 19:28:40 2007
LHidFilt LHidFilt.Sys Wed Apr 11 19:28:36 2007
LUsbFilt.Sys Wed Apr 11 19:28:42 2007

5) Update your very old C-Media audio driver from the motherboard manufacturer's site:
c6501 c6501.sys Wed Feb 07 05:18:04 2007
6) Update the video card driver:
nvlddmkm nvlddmkm.sys Fri Jul 09 17:15:58 2010
Link Removed - Invalid URL
7) Update your NVIDIA nForce chipset drivers. They are ancient and known problems on Windows 7:
nvm62x64 nvm62x64.sys Fri Oct 17 17:01:06 2008
nvstor64 nvstor64.sys Mon Jul 02 20:35:58 2007
Download the nForce package at the link in step 6 too. If you can't find the one applicable for your motherboard, then visit the motherboard site for it instead.
These must get updated no matter what, so let me know which motherboard you have if you can't find success with this.
8) Enjoy.
