Hi Violet,
sorry to see issue's cropping up again. This Bugcheck can be caused by gpu drivers passing bad data and can also be linked to possible memory issues too. I'm pretty sure this is your system but there doesn't seem any recent updates on the support page:
http://h10025.www1.hp.com/ewfrf/wc/...3&lc=en&cc=us&dlc=en&sw_lang=&product=4299475 Violet did you try and remove the original Windows update that started the issue or is it still installed?

AVG and installing MSE for the interim (it's very stable):

BSOD issues in Win7 with 2009 driver please update:
http://www.microsoft.com/hardware/en-gb/d/xbox-360-wireless-controller-for-windows If after making the above changes you still get the bsod then you need to test your RAM.
Windows does have it's own memory testing app but it can often miss errors and the best app for the job is Memtest86. The latest version of which can be found here:
http://www.memtest.org/ To run Memtest86 you need to either burn a copy of it to disk or use a USB stick. If you look down the page you'll eventually find the latest version and it's associated downloads. If your burning to disk choose the pre-compiled iso zip. If your using a USB method then the corresponding download is the auto installer for a USB stick.
Once you have Memtest86 on the media you selected you'll then need to enter your bios and change the boot order so that the machine will boot from either the disk or stick you have Memtest86 on.
Try and run the test overnight if possible unless it becomes clear that there is a issue. If there is a problem with the RAM you'll see the errors pop up in red so you can't miss them.
