on Cathy's issue:

a) yup, GH's answer. Loose cables
b) and yes, badsektor's answer. Changed CMOS configurations. This is a more probable answer.

Cathy, i can help if you are in Las Pinas/Alabang/Makati area. Walang halong malisya...

Bogeyman's issue:

A vbs is a visual basic script. Could be that the operating system was infected by a virus. I would suggest not to do anything with the DASD first, but to:

a) Boot in safe mode.
b) Check to see if it is still recurring.
c) If it still is, try to boot from CD, and scan it from there.
