What may be the problem?

It appears that your system is freezing when attempting to run in Parallel mode. This is a known issue with the UEFI BIOS firmware for your motherboard. See this forum post for details:

We have been in contact with ASUS in resolving the BIOS issue. They have acknowledged the issue but did not give a timeframe for when they will release an update. As a workaround, however, you can configure the CPU selection mode to 'Single' before running the tests.
