When I start up my
it is probably a program that starts up overloads the system resources, so everytime it starts it freezes. what you can do is go into safe mode (go into safe mode by hitting f8 right before windows logo comes up when you start your computer, or right after dell logo. either that, or if you restart it wrong, it should give you the option of going into safe mode) then when you log onto your account, a window will pop out, just click yes. then either go to start menu on run(if you have windows xp) and type msconfig. then a window will pop out, when it does, go to the startup tab, and uncheck all of the boxes. click ok, and click restart, (for windows 7 its the same thing but instead of using run, just type it in the search bar on the start menu). go to start windows normally, if it still doesnt work, when you restart it, go to last known configuration. Hope this helps. If you need any clarification, just let me know, ill check in. Goodluck
