I am not sure of the make with the parts I built it back in '08, but I am running on windows xp home. is they're any way to lower it details please.
system idle isnt a legitimate process, it just tells you what percentage of time your CPU is idle, you want that to be near 100% if you arent doing anything.

btdna.exe is a torrenting program. If you dont torrent then it shouldnt be running, check in add/remove programs in control panel and see if you can remove it.
BTDNA is a bit torrent client. If you are not downloading or file sharing you can remove it fron the controll panel/add remove programs
System idle process is the unused processor cycles. if it reads 90 or 99 that is a good thing.
I would worry about the btdna.
