FYI (I never saw this thread before now, so I was unable to help)...
Notebook/Laptop/Mobile GPU drivers are a sorry state of affairs, and have been for a LONG, LONG time. The problem is that AMD/Nvidia don't provide the "full system" to the notebook vendor, as they do for desktop-style GPUs (where they build and ship a reference card). This means that there is considerable physical differences between the different vendor implementations, even when the chip in question is on the CPU itself.
Unfortunately, this also means that you're as-often-as-not stuck with whatever driver the OEM provides, and they generally stop pushing updates after 1-3 revs (and often leave them considerably buggy still). Both AMD and Nvidia provide "mobility" versions of their drivers, but these ARE NOT guaranteed to work with all OEM implementations (and generally work best with those that stick closest to "stock", which usually means the big, ugly, heavy, cheap laptops). And, unfortunately, HP is notorious for shipping-and-abandoning their platforms...
Here's a guide from someone on HP's forums that might help if you need to bump your drivers:

For example, this guy releases his own mods of the official AMD Radeon drivers, which work with many HP-branded notebooks:

A hard-lock (where the mouse stops moving and you have to force the computer off) or a BSOD
cannot be cause by user-space software like MC on modern Windows platforms. If you get a BSOD or hard-lock, and it isn't while you were trying to do something "fancy" (like using a BIOS updater or something), this is caused by one of the following:
1. Hardware driver bug or issue.
2. Virus or malware activity.
3. Windows
itself is corrupt or broken in some way.
4. Hardware failure.
It
cannot be anything else. The only possible exceptions are software packages that install their own kernel-mode drivers, anti-virus, or low-level system utilities (which are rare enough these days). MC is not one of these, and almost anything else that you find out there that isn't a "hardware driver" or "utility" would qualify either.
Games and 3D programs often expose underlying weaknesses in drivers and seem to "cause" Blue-Screen crashes. But what a blue screen crash means is that there was a physical HARDWARE fault. MC is not allowed to directly access the hardware by the operating system. All actions have to be taken through interfaces provided by Windows, and it's memory access is "protected". This is one of the major benefits to the Windows NT/2000/XP/7/8 kernel over the older Windows 95/98/ME style kernels. Back in the old days, it was possible (common, even) for user-space software to cause these kinds of issues. But that has been long-since solved.
