Hello, new here. I am having an issue with excessive usage of memory on my system. First off system specs are; Dell E1505 T7200 2Ghz x 2 1G RAM ATI X1400 120G HD. XP Professional. When I turn on the computer and let everything fire up if I then go to task manager my memory usage is over 800MB with nothing else running. Now I do have a program that runs in the background for my work. It's Siemens HMI programming software and uses about 100MB. What I don't understand is why things like my anti-virus are consuming 300MB of RAM. It is TM Pc-cillin. One process in particular, PcCtlCom.exe, is using 183,xxxKb all the time. I can turn off all of the TM services and this amount of usage never decreases. Only if I turn of the anti-virus completely does it go down. Then it just goes away. I have contacted TM and of course they are of no help. They can't fathom what might be causing this. TMProxy.exe wants 75,xxxKb. Anyway, back on subject, I am having slow performance issues and computer lock ups. When I open My Documents it takes several minutes for the folder to open. I have tried Registry Mechanic but that didn't help anything. I have not updated my BIOS as I am not confident I would do it correctly. I cannot afford to screw this computer up right now as my work would suffer tremendously. But the slow performance is causing it's own set of issues. Here is a screen shot of task manager from a few minutes ago; "Screen shot removed for newb reasons. Will post later if needed" Anyway if I left out anything you need to know I will be glad to give you the info. I am not really very experienced at troubleshooting PC problems yet. Thanks for any and all help or ideas you may have. Greg.
