While playing Skyrim a few days ago my laptop shut down with a black screen and the power light was on. I restarted my laptop and everything was fine until I tried playing games again. I found this hotfix from MS that might help me to fix this, but it wouldn't install (This update is not applicable to your computer). Most of the crashes did not generate a dump file but here is one that I found using WhoCrashed. I also used MSI Kombustor to stress my GPU and it crashed my laptop. Any suggestions? Help is appreciated :)
Specs:
AMD Phenom II N870 Triple-Core 2.3GHz
4 GB RAM
ATI Mobility Radeon™ HD 4650 1GB GDDR3
Windows 7 Home 64-bit
500 GB HDD
Dell Inspiron M5010

On Tue 5/11/2013 12:41:16 PM GMT your computer crashed
crash dump file: C:\Windows\Minidump\110513-37346-01.dmp
This was probably caused by the following module: atikmdag.sys (atikmdag+0xABE8A)
Bugcheck code: 0x1000007E (0xFFFFFFFFC0000094, 0xFFFFF88004AE1E8A, 0xFFFFF8800236CF68, 0xFFFFF8800236C7C0)
Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M

product: ATI Radeon Family
company: ATI Technologies Inc.

Bug check description: This indicates that a system thread generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: atikmdag.sys (ATI Radeon Kernel Mode Driver, ATI Technologies Inc.).

Thanks for the reply.
I suspected it was heat at first, so I dusted the heatsink but the problem persisted. I tried updating to 13.9 legacy driver, doesn't fix the issue. So I uninstalled the amd driver using Driver Sweeper and installed 11.8 driver and it is still not fixed. Any other suggestion?
