I can tell you're using Windows XP......
......if you were on Vista, it would of never happened ;D But then again, you'd be playing games at 10 less FPS too. Heh.
It happanes usually when the RPC Locator gets anal raped by Malware, it could be a trojan or it could be adware or it could be a hacker literally getting into your computer RIGHT THEN AND THERE or it could be a dodgy driver.

The Service Layer had a big overhaul in XP SP3, there's lot's of redundancy checks for kernel stacking, and if some kind of override (usually an overflow are easiest to detect and most common) from the attack isn't prevented but still detected, Windows XP will purposely kill the RPC Locator (or something else depending on the nature of the failure) to force you to restart, as a security breach has occured. It's a "last resort" activity of Windows NT and has been there since Windows 2000. Windows Vista had a massive overhaul to it, this is why all the top cracker/hacker teams use Vista ;) lol. But as I said, a dodgy driver can also cause this behavior. For this reason, 64-bit OS's are more stable because they require signed and certified drivers (ensuring no memory leaks, security backdoors or stability issues). Anywho....
My advice, if you use torrents PeerGuardian 2 is a 100000% MUST HAVE SECURITY software, otherwise azn milit0r haxx will fire scuds at ur router all day. And use a good Security Suite, either Kaspersky or NOD32, all the rest are kinda spoon or memory hogs or have arses in detection rates.
Spybot Search & Destroy and SUPERAntiSpyware are among the best system sweepers too, SUPER was rated #1 for rootkit removal (something that XP is still very prone to).
And of course, keep Windows up-to-date. If you hate Windows Update, or can't use it for some reason *wink* *wink*, check out autopatcher.com
Or upgrade to Windows 7 RC1 (which is faster than Vista and more stable, I use it).
Or move to Linux and spend the next ten years learning the operating system and never having fun *cackles*
EDIT: I assume you are at LEAST on XP SP3, right? SP2 is literally a minefield to use online, yes it's become dangerous that quick. Other day, I installed XP SP2 in VMWare, with the mistake of giving it Internet access, instant rootkit.... browser hijacked.... *sigh*.
