So I've been running XP and a couple weeks ago I noticed my machine started to act strange. When rebooted and everything is loaded, I've noticed something was hogging up all my resources, so I run Task Manager and I find that one of the svchost.exes is the problem. So I kill that process and the system goes back to full speed. Of all the svchosts, the one i kill everytime is the one w/ the longest list of threads/processes (it doesn't crash xp). But I wanted to find out EXACTLY what is wrong, so I pinpointed to what I think is the problem. I think it's Winmgmt.Exe inside that svchost.exe, because when I pause it, the system reverts back to full speed. Task manager doesn't show svchost.exe to be always eating up 99% of the cpu, while it does do that sometimes. But most times the system is just lagged to death doing anything w/ the hard drive running. I tried all sorts of AV and spyware removal, but nothing came up. Does anyone have any other ideas?
