My Laptop sometimes crash after installing SP1

[LamSoft]

My laptop is Targa Visionary 1800+

When running Windows 9X/ME, it works fine, no problems.

When running Windows XP without SP1, it sometimes crashes.
But with SP1, it crashes a few times each day.

I ensure that all driver are come from the Orginal CD and have WHQL
Certified, and installed VIA 4in1 Patches.

Crahes ==> No repsonse after crash, the keyboard & mouse do not give any
response on the screen, emust reboot to make it run again.
There is no any oems or signal on the screen before
crash.

Thanks a lot.

Hi,

You can use Event Viewer to view and manage the event logs, gather
information about hardware and software problems, and monitor Windows
security events.

To view the event log: Administrative Tools/Event Viewer or
Start/Run/eventvwr.

To review Shutdown Event Tracker data, Open Event Viewer. Click System Log,
scroll to the Event column, and find entries with the number 1075.
