[I apologize for the duplication in posting. I must have accidentally hit the Post Message button. Then when I went to edit the post, it didn't seem to work...] Gigabyte GA-Z68A-D3H-B3 Motherboard Intel Core i5-2400 Sandy Bridge 3.1 GHz 1 Terrabyte Seagate SATA HDD 16 GB DDR3 SDRAM Memory Windows 7 Pro Today I had my 3rd BSOD in 2 days. The Event Viewer also shows one that occurred during the machine's build the day before I picked it up. I have mini dumps for 3 of these. BlueScreenView from NirSoft shows "Caused by Driver" BSOD #1 dxgkrnl.sys #3 atikmpag.sys #4 dxgkrnl.sys I have compiled a .zip file with files created from the SF Diagnostic Tool, screen prints of CPU-Z info and .html output from RAMMon but did not see how to attach this. Any thoughts on troubleshooting this would be appreciated. Thanks.
