Can someone tell me what of the test programs would work well for my Dell 5110 W7 pc? It just about has to have some kind of hangup with hardware or something that is causing it to hardly be able to play videos. I tried passmark but for the life of me I cannot find what are the numbers that it should have. I spent about half an hour trying to get pcmark installed and I finally quit on that. What would be a good test program and where do I find what those numbers should be/mean? Thanks for any help.
