System Error, Blue Screen, MiniDump

[Eddy]

Hey everyone, my name is Eddy and I need help.
I'm attempting to fix my friends computer so far I've "patched" it.
I scanned computer with NOD32 and CounterSpy.
I removed unnecessary software.
I removed a cd-rom writer because it wasn't compatible.

Here are the computer specs:

CPU: AMD Athlon XP, 1466 MHz (11x133) 1900+
Motherboard: Asus A7V8X-X
Chipset: VIA VT8377 Apollo KT400

And this is the system error:

Error Code: 10000050
Parameter1: e23e6000
Parameter2: 00000000
Parameter3: 8056b9ac
Parameter4: 00000001
Category: 102
Event ID: 1003

Any suggestions, will be very appreciated.

Eddy
