Hi there - I've just recently had an odd problem surface on my machine. This is my first time requesting help here, so please bare with me. I'll try to be explicit. I just recently discovered that my computer is constantly accessing the harddrive no matter what. Every second or so, there's a pulse on the HD light and a noticable sound from the HD itself. This is odd to me, because this usually doesn't happen when my computer's idling. When checking the task manager, I noticed that explorer.exe and winlogon.exe are both generating HUGE numbers of page faults - And winlogon.exe in particular is creating quite a few for no reason (I can't even imagine what winlogon.exe is doing). I thought it might be a virus or malware. Norton came up with nothing, and I double-checked against Panda ActivePro as well. Both showed I was clean. Similarly, Spybot S&D and AdAware came up with no problems either. Running a netstat showed no open connections when my computer was idle, too. Does anyone know what might be causing this? I'm a little uneasy knowing my computer is chugging away even when I'm not asking it to do anything. It makes me feel like something's very wrong, and sometimes it prevents my computer from turning off the monitor for powersaving. Here are my specs: Pentium 4 3.2 GHz 1 GB RAM - Corsair (I'm forgetting what speed it is, I think PC300?) ABIT AI7 motherboard Windows XP SP2 - up to date according to Windows Update Western Digital Raptor 74 Gig HD Sapphire Radeon x800 pro Soundblaster Audigy 2 Any help that anyone could provide would be most appreciated. Thanks!
