I noticed from the log that you have a Dell computer. Dell computers come with a diagnostic CD that you can start your computer with and run a full set of tests to check to see if you have a hardware issue. Boot up with the CD, and run the tests to see if anything fails. If so, write down the error messages(s) and reply back to this topic. If you do not have the diagnostic CD, you could download it from the Dell website.
If you are stuck, reply back to this topic and we can try to help you.
By the way, what is the exact make and model of your Dell?
Here's what I found about your stop message...(from

0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP
(Click to consult the online Win XP Resource Kit article, or see Windows 2000 Professional Resource Kit, p. 1558.)
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.
Good-luck.
