Hey, this is my first time posting on the forums and I'm asking for help as I'm a complete beginner with most things related to computers. My computer boots up normally and after logging on to my account I briefly see my screensaver and start menu with all my programs saved to my home screen. However soon after seeing this my screen turns white with a movable mouse. I am able to access the Ctrl Alt Delete Menu, however after selecting start task manager it goes back to the white screen. Furthermore when shutting down I briefly see my programs and screen saver again. I run Windows 7(64 bit) and during the white screen my mouse looks like it is loading something. I would really appreciate any sort of assistance. Thank you in advance. Before posting this thread I tried it one more time. It was in effective but upon logging out like I stated previously it disappeared. I managed to cancel the log out and now I'm on my operating computer. But I highly doubt that has solved the problem.
