0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP
One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2) Software problems. (3) A bound trap (i.e., a condition that the kernel is not allowed to have or intercept). Hardware failures are the most common cause (many dozen KB articles exist for this error referencing specific hardware failures)
and, of these, memory hardware failures are the most common.
So the first step is to run memtest on your RAM:
1. Go to
www.memtest.org and download the latest ISO version. It is free and perfectly safe.
2. Burn to a CD.
3. Place CD in your drive
and reboot with CD in drive. The test will take over.
4. Let it run for a LONG time. The rule is a
minimum of 7 Passes. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.
5. If you have errors you have corrupted memory and it needs to be replaced.
6. Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test.
