My PC is being a bit weird and will not let me use my applications. When I turned it on, it was applying updates and took awhile for me to log on. When I got logged on to my account, a bunch of "Windows can't open this file" windows started popping up. These processes showed up when I opened Task Manager in the processes tab. There were no applications running in the applications page. I did not stop any of these processes. It said, jusched.exe, LitModeSwitch.exe, SetDefaultSCR.exe, IAStorIcon.exe, LJYZ.exe, iusb3mon.exe, ServiceLoader.exe, MUIStartMenu.exe, AdobeARM.exe, MUIStartMenu.exe, TBNotifier.exe, CLMLSvc.exe, LenovoReg.exe, hotkey.exe, Skype.exe, YahooMessenger.exe, PMB.exe, BJMYPRT.EXE, vsnpstd3.exe, RAVCpl64.exe, msseces.exe, MUIStartMenu.exe, NvBackend.exe, rundll32.exe, NvTmru.exe, wmdcBase.exe, CNSLMAIN.EXE. I can still open files and pictures and music but I can't open anything like Google Chrome, Skype, or any of my games. I have a Lenovo K430 with 2TB, a Third Generation i7 processor, and 8 GB DDR3 RAM. Windows 7 Home Premium. Please help in anyway you can.
