The blaster worm affected the RPC event and changed this service setting - if stopped, then reboot machine basically.
If you go to services, and check the RPC service, you can see the options there.
Not that the information above really helps...
WOW @ that error message on the BSOD... thats a new one.
Here's some info I found:
This message means WinXP crashed because it was asked by a driver to complete an I/O operation which had already been completed. This is usually a software configuration problem, e.g. you may have a problematic driver on your system that needs to be removed or updated. But sometimes this can be caused by hardware corruption.
Do you use a program called FOLDER SHIELD?? This may be related it seems - unistall!
Microsoft link (for 2000, but relative to XP):
http://support.microsoft.com/?kbid=294876Seriously thought, it sounds like you damaged something when you touched the inside. When the PSU blew, it may have damaged a component (a small resistor or anything like ram or gfx), its likely to be a hardware issue, which basically means getting someone to fault find it, or do it yourself by removing non-critical hardware piece by piece...
good luck!
