Hi, I have a Sony Vaio, Intel I 5 3337U cpu. & 1.8 ghz. 8 gb ram, Windows 8.1 64 bit operating system. I am having trouble with my computer running slow, when I try to re-start it takes 20 min or longer sometimes, and when it gets to what should be the signin page it shows a window box that says "C:/Windows\system32\logonUI.exe". If I hit the X on the window to exit out, a new window says "press Ctrl + Alt + Del or exit window to login " when I press the Ctrl + Alt + Del then a login prompt comes up. I enter my pin, then it says "Welcome" and enters into the desktop , but takes a while to load.
I don't understand why my computer is taking so long to start or shut down... which ever, and why it is not showing the correct screen upon starting. I have not added any programs, or anything before this started taking place. Oh and I forgot sometimes the sound does not work until I reboot, and times videos will not play.
Hope you can help me, I sure would appreciate it.
