I'm having a weird problem with my computer. I used to be able to leave my computer on for extended periods of time, and it would run fine. Now, I find that if my computer is on for too long, my svchost.exe processes get incredibly bloated and end up using 70% of my physical memory even when no applications are running. When I start the computer fresh, it's back down to 35% (right now it's 39% with Firefox open). Any idea what would cause this? I have a 4 year old gaming PC. It was above average for it's time, but now it's starting to be challenged by today's games. I have 4 gigs of RAM and a quad core processor. The system should NOT be using so much memory with no applications running. I guess restarting it isn't such a big deal. It's recently started giving me random BSODs shortly after start up, which is why I avoid doing it, but I'd estimate it only does that 10% of the time. Once it's been running for a while, it doesn't blue screen. It only ever blue screens within a few minutes of a restart for the times it does. I'm not as concerned about that as I am about the svchost.exe process that starts at 130k ballooning to 400k of memory.
