Solved Random Black Screen Freeze, not after login

I own a Gateway NV52, and the issue with locking up began after I upgraded to Win7. After reloading the factory default of Vista on this, the laptop keeps randomly locking up and then going to a blank black screen.

I've gone to other threads and tried running MemTest and Vista's Memory Diagnostic and they both came up with nothing. I've also seen that other posters have attached dump files and other generated information from the computer to help solve their issues, but I don't know where to find these files to even get started. Can anyone help? What other information do I need to give to get started on the right track?

I would first do a system file check.

Then you can view any error messages and see what they mean from this Microsoft site.

How to analyze the log file entries that the Microsoft Windows Resource Checker (SFC.exe) program generates in Windows Vista

If errors are found run the test again as it sometimes takes about 3 passes to get it all fixed. Sometimes even that fails to repair it but post back with results and we will take it from there.

Command prompt says it cannot open the file
