After noticing some virus issues when i boot the computer and choose the user it starts loading windows but never fully does. the start menu never show up or does any of the desktop icons. i can get task manager to open but can not get anything else to come up. I did not know if there is a certain virus that needs removed or if a certain file in the operating system needs replaced. I have ran a chkdks /f but still not luck on getting anything to come up in windows. Any suggestions on what to try would be appreciated.
