XP Pro restarts by itself

[byroncheng]

For some strange reason the computer keep restarting by itself. I do not have
anything running nor was i even using it at the time. I do not have automatic
updates set to fully automatic, so it should install updates by itself, hence
restarting on its own.

I have checked event log and found the following at the time of the restart:

The computer has rebooted from a bugcheck. The bugcheck was: 0x1000007f
(0x00000008, 0xbab38d70, 0x00000000, 0x00000000). A dump was saved in:
C:\WINDOWS\Minidump\Mini021408-02.dmp.

not sure what it means nor do i know how to trouble shoot the problem..

any ideas???

Background information on Stop Error message
http://msdn2.microsoft.com/en-us/library/ms795478.aspx

0x00000008, or Double Fault, indicates that an exception occurs during a
call to the handler for a prior exception. Typically, the two exceptions
are handled serially. However, there are several exceptions that cannot
be handled serially, and in this situation the processor signals a
double fault. There are two common causes of a double fault:
A kernel stack overflow. This overflow occurs when a guard page is hit,
and the kernel tries to push a trap frame. Because there is no stack
left, a stack overflow results, causing the double fault. If you think
this overview has occurred, use the !thread debugger extension to
determine the stack limits, and then use the kb (Display Stack
Backtrace) debugger command with a large parameter (for example, kb 100)
to display the full stack.
A hardware problem.


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.

In essence you have two areas where the problem could be. A software
problem ehich could difficult to determine and a hardware problem where
it is easier to eliminate some of the possibilities. I gave a link
regarding ttouble shooting hardware:
http://www.elephantboycomputers.com/page2.html#Hardware_Tshoot

Dust inside the computer casing can cause overheating and result in this
type of error. Take the casing off and use an Air Duster to clean. Also
check that all fans are working.

Try HD Tune(freeware) as you can see the SMART
information relating to the drive etc.

Download and run it and see what it turns up.
http://www.hdtune.com/

Select the Info tabs and place the cursor on the drive under Drive
letter and then double click the two page icon ( copy to Clipboard )
and copy into a further message.

Select the Health tab and then double click the two page icon ( copy to
Clipboard ) and copy into a further message. Make sure you do a full
surface scan with HD Tune.

You need then to test the RAM. Please refer to the link on how to do
this.

If these measures do not identify the cause of the problem you would be
best to seek professional help. The power supply unit can only be tested
by swapping in a replacement and most home users do not have a spare one
to use. The software diagnosis is beyond the capabilities of most users.
