I am not sure what to do .I was on with the tech at Verizon and he looked for the msconfig files to see what I had running when I started up. I don't know much about this He told me I could uncheck boxes on this system config and they still could be used it is just that they would not start up when I sign on and be running in the backround. It would speed up my computer also. Then when I wanted them I would just click on them . Well when I went to that file it says start up and services and I dont know which to work on.Also I had to reinstall my windows xp and when I did or the person that did it for me said there was a choice to use fat32 or nf something or another and we choose fat32.Now when I sign on I dont have a run in the start up and this message keeps coming up about taget or something like like which is a dllfile it says it is missing.If you put the disk for windows xp in and hit repair will it load what it missed?
