How to open Event Viewer
If you can start Windows XP, check the System Log in Event Viewer for additional error messages that might help identify the device or driver causing the problem. To view the System Log click Start and then click Control Panel. Click Performance and Maintenance, and then click Administrative Tools. Double–click Event Viewer to open it and then System Log to view.
See if you can tell us what it says in there and if it lists a particular file, driver or device.
Do you know exactly how long this problem has been occurring?
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.http://aumha.org/win5/kbestop.htm
General causes of "STOP 0x0000007F" errors
The above STOP error means a trap occurred in kernel mode and the trap is either one the kernel is not allowed to have or is always fatal. The most common causes of a STOP 0x7F are:
• Low-level hardware corruption, such as corrupt memory (RAM)
• Mismatched memory modules
• A malfunctioning motherboard

Lets start with the RAM, as that is a common reason for this:
