One problem source eliminated.
I found the following old drivers
on your system:
scmndisp.sys Jan 17 2007 - This is a Netgear driver
by Neutral Wireless Solution. I recommend that you update this driver.
nvm62x64.sys Oct 17 2008 - Google "nvm62x64.sys" and see if you can find an update for it.
After you have updated these drivers, especially the first one. let's see what your system is doing before we take the next steps.
