Windows Xp Black Screen no taskbar or start

Okay well today i went to start up my computer.It started normally but when i signed in i got a error. The error said explorer. exe- Application error The application faailed to intalize properly (0xc0000022) click ok to terminate application. afterwards multiple more errors come up saying Microsoft mobile pc presentation adaptability client has stopped working, Windows calander has stopped working, windows explorer has stopped working. As if that wasnt enough for some reason all it signs into is a black screen. there is no start menu and the taskbar is completely gone. i was able to access things through the taskbar but all of the things i have tried have failed.

things that i have already tried:
1. I tried to system restore, didnt work.
2. Went into safemode to see if i could find the problem. was unable to and i tried to system restore from there also.

Im not that adept when it comes to computers, any help that can be offered would be greatly appreciated. Thank you.
