This weekend I was investigating the capabilities of the two NVIDIA graphics cards in my laptop and a password cracking application called oclHashcat. The oclHashcat application uses OpenCL, the Open Computing Language, to utilize the processing power of your graphics cards GPU’s to crack passwords. My laptop is a Dell Studio XPS 1340 which utilizes Hybrid SLI technology to offer a good amount of graphics power while using the least amount of battery life possible. The laptop accomplishes this by mostly using an NVIDIA graphics card, which is a NVIDIA 9400G M, that is installed on the motherboard and only calling the second graphics card, which is a NVIDIA G210M, when it needs to render something in say 3D or higher quality than the 9400G M is equipped to handle. One thing I happened upon during my research was an NVIDIA utility that will easily allow you to overclock your NVIDIA graphics cards which I describe in more detail below.
I have been really satisfied with the Dell Studio XPS 13 running Windows 7 Ultimate 64-Bit that I purchased at the beginning of the year however recently the C: drive displays dirty on boot thus triggering a chkdsk. The problem is that sometimes the boot screen would simply hang at 1 second left before the chkdsk would run. This would happen regardless of if I hit a key to skip the chkdsk or if I let the chkdsk run. Below I describe some of the things I have done to get around this problem.
When I first got my Dell Studio XPS laptop I would get a popup asking for me to specify what was being inserted into the audio jack. At some point I must have reconfigured this and forgotten exactly how I did so though I did remember that it was something to do with reconfiguration pop-ups. After searching around I finally found where you can enable or disable the Audio Jack Reconfiguration Pop-Ups on Windows 7. Follow the directions below to enable the reconfiguration popup on Windows 7 with the IDT software installed.
