Laptop locks and black screens when it tries to go into DX9 complex. I have tried to run them all independently of each other and all DX tests black screen except DX9 simple. Thanks.

This sounds like is most likely a driver issue, a quick check of our baseline database shows 18 Quadro K620M results, none of which use the same driver version as you. The two drivers used were both older (341.01 and 345.20) so it might be worth trying to install one of these versions and see if that allows PerformanceTest to run.
