Help! a svchost.exe is consuming all available memory on my machine. Details: -Windows XP Home Edition, SP3 -Just reformatted the hard drive, reinstalled everything, ran all the windows updates. -Comodo Internet Security 3.11 I ran the 8 steps on this computer a month or so ago, and couldn't resolve the svchost.exe issue, so I reformatted. Problem is back. I did fresh installs of all my software, and partitioned my hard drive so all data files are on a separate partition from the OS and program files. Not sure what other details I need to provide, but I really need some step-by-step troubleshooting guidance. It's pretty frustrating to spend a weekend rebuilding this thing to continue to have the same problem. Thanks! EDIT Just installed Advanced Task Manager. Looks like the culprit might be "HP Network Devices Support". I have 2 HP devices, a printer and a scanner. Scanner is hardwired to PC, printer is on network, not hardwired to PC. 3 HP programs in Add/Remove Programs window: -HP Photo & Imaging 2.2-Scanjet 3970 Series -HP Imaging Device Functions 9.0 -HP Photosmart Printer Software Are any of these the cause of my problem?
