I have build 6801 of windows 7 and for when i discovered that for some reason my computer was working at 100% all the time for no apparent reason, both cores and the harddrive LED on the computer is at full workload. What's happening how can I help better describe my problems? My computer is a HP Pavilion dv6247ea dual core 2 1.66ghz intel with 2gb ddr2 ram and 160gb 2"5 so the specs are alright, was enough for vista so it can't be that. I can't bring up my Task manager after waiting a while seeing only a blank screen an none-aero rendered window popups and says "Login process has failed to create the security options dialogue." And this whole problem is fairly new after reformatting yesterday, before that I had another windows 7 install and never had this problem so I don't understand why it would work at first but not now, what's happened, what's changed? Any help would really be appreciated, if you would like I could allow remote access to my computer via TeamViewer.
