I hoard my resources and hate the idea that something that doesn't need to be running, is running. In WinXP I was all over Black Viper, until I discovered that he really didn't research, really didn't know what he was talking about, in fact I think I spent more time investigating whether or not a Service was necessary than he did. Sometimes he said it wasn't necessary for most Users and it was, and sometimes he said he didn't know when the consequences of turning something off were pretty immediate and pretty clear. Anyways, it's Windows 7, and WAY more complex and I just don't have the "oomph" anymore to fiddle and tweak, but lately I've been experimenting with Process Explorer and there's 3 different things running labeld "NVIDIA" and they are ALL bugging me as I suspect I don't need any of them, but I'm checking here in order to find out for certain. Yes, I KNOW I can just "suspend" or "kill" them, but I want to know what it is that I'm suspending and/or killing, why it's there in the 1st place and what might not be working in the future if I turn them off. My system is a bit buggy, I suspect a hardware issue (video), but cannot say for certain. So I don't want to just assume that because the system doesn't BSOD or something similarly dramatic, that means that NOTHING happened, because if something odd happens the next day, I'll wonder if it's because I disabled one (or all) of the NVIDIA softwares.
