Looks like your SoundBlaster drivers are causing grief. Download the latest version of SB drivers for your sound card. Uninstall the old drivers; then install the new ones.
If this does not help move your SoundBlaster card closer to your video card. PCI slot#1 or #2.
Your video card overclock kicks in due to a bug in your overclocking tool. See if you can get the latest version of drivers of ATI card + update you OC tool.
Good luck.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 00000000, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: b2f7d077, address which referenced memory
