When my computer starts up it opens windows. This mm_tray.exe has failed to start and core.dll is missing and my computer wont open anything not even task manager. sometimes windows would recover itself but only after so many resets and that cant b good for the computer. Someone help please

As far as I can ascertain, MMTRAY.EXE is related to 'MusicMatch Jukebox', and CORE.DLL related to 'RealPlayer'. Neither file is part of a standard Windows installation. perhaps re-installing those two apps may cure the problem.

Did this just start to happen?

Have you tried booting into safe mode & doing a system restore & or try to boot last good configuration?

also try to open the command prompt & type in chkdsk/f
choose Y to run on next boot.

What were you doing to "reset" windows ?
