Overclock NVIDIA G210M & NVIDIA 9400G M GPU’s In A Dell Studio XPS 1340

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.

Windows 7 Ultimate 64-Bit: C: Drive Shows Dirty, Windows 7 CHKDSK Every Boot

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.

The AC Power Adapter Type Cannot Be Determined, Please Connect A Dell 90W AC Adapter

Last night I upgraded the BIOS on my Dell Studio XPS 13 from A11 to A14. The BIOS upgrade appeared to work without issue however when the computer rebooted with the new BIOS version I received a boot error and then once I skipped the error I received a popup message within Windows 7 as well. The problem ended up being something really silly which is explained below but I wanted to note in case someone else ran into the same issue.

Windows 7 IDT Audio Jack, Allow Reconfiguration Pop-Ups

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.
