Ok it took my kids exactly 6 months to do something to their computer that causes it now to not want to install anything new. Let me give you an example of what I mean. They have a brand new Logitech QuickCam. We followed the install directions EXACTLY. The drivers & software load fine from the CD. When the camera is plugged in it is recognized. This is where we have issues. The camera and the drivers never connect. If you then try trouble shooting and manually selecting the drivers you get a Windows error message (28) telling you there is no data. The very same thing happened with a brand new Microsoft keyboard. FYI - it doesn't matter if you connect the keyboard via USB or PS2 port - same issue. When I poked around in the Device Manager I found the following issues: -One DVD Combo drive is disabled and Windows is unable to enable it. (Note: this drive appears to be working fine. It reads both CDs and DVDs). -After clicking "Show Hidden Files", the following items under "Non Plug & Play Drivers" have yellow exclamation points: -- _ishieldA -- _ishieldB -- catchme (this resolved itself after a reboot) I have run AVG, Ad Aware, SuperAntiSpyware, CCleaner, Malware Bytes, Defrag, Disk Cleanup, ATF Cleaner, SD Fix and HiJackThis. Nothing seemed to find an issue. I am attaching my latest HiJackThis Log. Computer specifics: eMachine T6212, AMD Athon 64Processor 3200+, 2G Dual Channel RAM, ATI Radeon XPress 200 Series, Seagate 300G SATA HDD The computer is about 3 years old. The hardrive is less than 1 year old and the RAM is 6 months old.
