You're using the Feb 09 version of your Nvidia driver, which I've been aware has been causing a lot of people grief. Your crashdumps also seem to reflect this as very frequently does it pop up as the suspected faulting driver. You'll want to update the driver.
If that does not resolve the issue, I recommend turning on Driver Verifier
. Do not
select the following checks: Force Pending I/O Requests, IRP Logging
, and Low Resource Sim
. Make sure to restart system after you finish setup. If you experience a boot loop afterwards, go into Safe Mode by pressing F8 prior to Windows logo and disable DV there. Provide us any new crashdumps.
Btw, I noticed you're using Windows 7 32-bit yet you have 8GB of RAM installed. You do realize that 32-bit can only see up to 3.2 GB of RAM, right? You may have the PAE extension available in Windows to see more, but this is not
a natural solution to the problem and it's highly
recommended you switch to 64-bit Windows 7.
Also, is this a very new system? If so, there's always a good chance one or more pieces of hardware is failing. We'll approach that if the Nvidia driver update doesn't work and DV doesn't pick up anything useful.
