Its done this since I reinstalled Windows when I got the new hard drive installed, not too long after I bought the laptop.
Right now, after leaving the PC running for 2 days and 22 hours, that exact process is consuming ~120,696K and utilizing between 3 and 46% of the CPU.
I will also like to point out, might be related, might not. However since I've owned this laptop, anytime I change Wireless APs after utilizing one for a short period of time (10, 20, 30 minutes) it will cause the RPC to crash and force Windows to restart.
Windows XP SP2 Build 2600
Wireless card: Intel(R) PRO/Wireless 3945ABG Network Connection
Not sure why it's always done that. It's just one of those things I've always just ignored. I hardly ever push the laptop to it's limits, so I hardly ever notice or been concerned enough to try to track it down.
With the upcoming game Battlefield: Bad Company 2 coming out I want to get the laptop running at it's optimum performance. I feel this might be a small issue, unless I restart the computer before I play the game.
Perhaps I could have a slightly faulty wireless card?
