restarts periodically

[Ty]

Hi my computer runs for awhile then restarts itself
unexpectedly. When it comes back on, it says the system
has recovered from a serious error.
-------------------------------
this is the error signature:
BCCode : d1 BCP1 : 00000009 BCP2 : 00000002
BCP3 : 00000000
BCP4 : 00000009 OSVer : 5_1_2600 SP : 0_0
Product : 768_1
----------------------------
and these are the files included in the report:
C:\WINNT\Minidump\Mini091203-07.dmp
C:\DOCUME~1\Tyler\LOCALS~1\Temp\WER1.tmp.dir00\sysdata.xml

Any help with this matter would be great. thanks

First, be sure your antivirus software has the latest definitions and run a
virus scan.

If your system is clear of viruses, open Control Panel, open Administrative
Tools, open Event Viewer, look for errors corresponding to the crash, double
click the error, the information contained within may give a clue as to the
source of the problem.

Assuming you have an XP CD and not a recovery CD, place the XP CD in the
drive, when the setup screen appears, select "Check System Compatibility,"
the report it generates may point to problem hardware or software on your
system. If you do not have an XP CD, you can download the this application
known as the Upgrade Advisor from the following site:

Note: If you have access to a broadband connection it might be best to
download using that as this is a rather large download.

Check for the latest drivers for your hardware, especially your graphics
card and soundcard and all peripherals connected to your system. No not use
Windows Update for this, go to the device manufacturer's web sites and if
you install updated drivers, ignore the message about drivers being unsigned
by Microsoft.
