I'm actually suprized that you guys missed this one.. Look at the last process in his list.. System idle process taking 97% of resources..
I bet your system has been running slower and slower recently too, to the point where sometimes other stuff takes forever to load, and sometimes doesn't load at all? Welllllll.. Guess what??
Pal, you got spyware and malware on that system.. Pick up a copy of cwshredder, hijackthis, and adaware and get the spyware off the system.. You are probably going to have to do a scan with hijackthis and post it to the forum so we can tell you what to turn off, because hijackthis takes no prisoners and you have to be carefull what you kill with that...
If you are lucky, It's not one of the nasty malware proggies, cause they can be a real pain to get rid off..
On top of that.. You have WAY too much crap running.. Just because you have a gig of ram doesn't mean that the CPU can thread all of that junk in a timely manner all at the same time.. That's why I hate buying a computer from someone else because they always have shiz loading on boot that no one every needs..
