Hi, I am new to this forum. I recently noticed my computer is slow, very slow. I have not been on the computer in question for a long time like 6-10 months or more. When ever I launch an application my computer will show the circle that goes around and then it stops like 10 seconds later and nothing happens, so I go to the task manager and see rundll32.exe is using 75-100 cpu and my computer slows, until I end the process. I have looked this up and found some answers, but all of them are outdated by at least a year or more. I didn't install anything yet nor the last time I used it, so if someone can tell me what pre-steps they need me to do, I will gladly. Thanks and sorry for any errors in advance.
Please note: The computer is not connected to the internet, so I have to download stuff via a USB then to the computer and install it. My internet connection on other computers is slow so it may take me a day or two to get back to this topic. Also, my computer is a 64 bit Windows 7 Home premium E-Machines, 500 Gb, I am only using 243 gb of the total hdd. Thanks again, I cannot risk formating this computer, it has a lot of important and unique things on it, pictures,videos,etc. I will try to do anything to make the experts job any easier.
