When I first built my computer and installed Windows XP, the thing ran great. It booted up super-fast, programs ran extremely well, and it was reliable.
Well, while the computer is still very reliable (I've never gotten the blue screen of death), it has become bogged down by background processes. There were five background processes running at any particular time when I built it, but now there are almost 60. Most of them just sit and do nothing but take up memory (which I expanded from 512 MB to ~1.5 Gigs recently). It's my processor now that is having a hard time.
I know that some of it could be spyware, adware, or similar programs, but I clean that stuff off regularly. Now I have things like Spybot-SD Resident, Windows Indexing, Norton Systemworks, Norton Antivirus, and a whole host of other programs running.
Maybe it's time to upgrade (replace) the machine. I should just throw in the towel and admit that it just takes a lot more processing power to do NOTHING AT ALL than it used to.
But alternatively, are there suggestions that you folks might be able to make to set me straight on some misconceptions that I may (probably) have or to speed up the compie a bit? I am not an expert (though I try) and I don't fully understand what all the background processes do. Why do I need 11 instances of Svchost.exe running? I know they have something to do with making programs like Firefox run smoothly, but it also seems to be the one eating up the processor when Firefox is trying to do something for me.
Thanks!
