According to Dell's specs for the e6410 your CPU is either a i5-520M, i5-540M or i7-620M. You can look up your CPU on Intel's website (or Google it, and the Intel page will show up first) and from there go to the downloads link on the left side of the page. From there I'd try the first Intel Graphics download there is. I suppose you could continue extracting the drivers to a folder and manually installing, just to be safe.
Also, be sure you reboot after each driver install. If you install the right driver but try running PixelCNC without rebooting it will still be using whatever driver was already present - instead of the newly installed one. Windows needs to boot with the new driver installed in order for software to be able to utilize whatever functionality the driver exposes, otherwise it just lies dormant, waiting for the reboot, so it can fully swap in the new drivers in place of the ones already being used.
I think the key is definitely going to be finding the right driver for your CPU's graphics functionality. You should be able to see exactly which CPU you have in the device manager under 'Processors', and google that. It should be something iX-YYYM where 'X' is either 5 or 7 and YYY is a 3-digit number.
All I know for sure is that your machine is plenty new to have at least GL 2.0 hardware built into it, and it's just a matter of hunting down the right driver.
