To begin, I would like to apologize if there have been topics similar to this one posted in the past. I simply don't have the time to browse through everything. I can only hope that you guys can provide some needed answers.
In the last couple of days, I have noticed that my primary computer (a Core 2 Duo desktop running Win 7 Ultimate - you can find its specs somewhere in my previous posts) has begun acting up. The two primary symptoms that I have observed are as follows:
1. The processor seems unusually loaded even when the system is simply idling. I tested this out for about half an hour after rebooting my system, and my processor usage hovered at an average of 50%-60%. I have a Core 2 Duo E8400 which though nothing new, is still a very decent processor. Normally when my system has sat at idle, processor usage was much lower, below 15% in any case.
2. The second problem I have observed is that my hard-drive space has been disappearing. I came home from classes today to find my computer telling me that I had only several kilobytes of space left. This is unusual considering I had in the neighborhood of 150-200 gigabytes free. I'm running a WD Caviar Green 650 GB HD. I ran several clean-up procedures to little avail and rebooted the computer. When Windows loaded again, I found the computer telling me that I had 189 GB of free space. Over the course of several hours however, this slowly dipped back down. The last time I checked before shutting my system down, Windows was telling me I only had 90 GB of free space. All this time though, the computer was idling with the Internet physically unplugged.
What I've done:
So far I've run several anti-virus sweeps which have uncovered nothing. I've also done a System Restore which has been similarly ineffective.
I am hoping that the Gerbil wizards on this site can help me out and at the very least, point me in the right direction. Any and all insight is welcomed and appreciated. Thank you.
