HELP!!! WIN XP SP2 BSOD STOP: 0x0000007E (0xC0000005 …

Please help, pleasesssss..

Update nothing, no software, no hardware, no winxp update. Then one day, on it’s restart, IT HAPPENS!!! out of the blue.

STOP: 0x0000007E (0xC0000005, 0xBACEA971, 0xF792A154, 0xF7929E50)

System config:
Windows XP Pro SP2 Traditional Chinese Version
AMD Athlon XP 1800+ CPU (1.54 Ghz)
2.50GB Ram

Checked no hardware failure, since I install a fresh copy of Windows XP Pro SP2 English Version on another partition, and it works. In fact, I am using it now to type this help message!

Any help will be much appreciated! Have been trying to work it out for nearly 2 weeks now. Please shed some light for me, any experts on there.
