Multiple BSOD errors

Hi TomPH and welcome to SF! :)
Please update these drivers:

Code:

GVTDrv64 GVTDrv64.sys Tue Sep 05 04:10:02 2006
DB3G     DB3G.sys     Mon Nov 07 04:33:11 2005

Here is how we recommend updating drivers:

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
- - The most common drivers are listed on this page: Driver Reference
- - Driver manufacturer links are on this page: Drivers and Downloads

Run Memtest86+ at least for 8 passes.
