i need help w/ a 0x0000008E error

[youngWilliam14]

i need help fixing an HP Pavilion dv5000 notebook that i use at competitions. i keep getting a blue screen that says:

A problem has been detected and windows has been shut down to prevent damage
to your computer.

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to be sure you have adequate disk space. If a driver is
identified in the stop message, disable the driver or check
with the manufacturer for driver updates. Try changing video
adapters.

Check with your hardware vendor for any BIOS updates. Disable
BIOS memory options such as caching or shadowing. If you need
to use Safe Mode to remove or disable components, restart your
computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

Technical information:

*** STOP: 0x0000008E (0xC0000005, 0x--------, 0x--------, 0x00000000)

Beginning dump of physical memory
Physical memory dump complete.
Contact you system adminisrtator or technical support group for further
assistance.

the two strings w/ dashes are different each time i get that screen. it comes up anytime i boot my laptop in any mode that has networking (i don't get the message in safe mode w/o networking).

i really need this problem solved soon, but i do NOT want to rewrite the OS (Windows XP Home w/ service pack 2) because i don't have any way to backup everything i have on the hard drive. thank you for any help!
