I recently made a custom build and have been having issues. From what I can tell, my computer is going slower than it should. Also, my screen periodically goes completely black. My programs also crash periodically. Please let me know what I should do to find out what the issue is.
ASUS P8P67 LE (REV 3.0)
Corsair Vengeance 1600 DDR3 (4gb, will have 4gb more when it comes back from repairs)
EVGA GTX 570 superclocked
some WDC SATA II 1TB HDD
