Windows loads to the desk top an quits

Hello, I have been having a problem loading windows for the past several day. It will start loading normally, but a few seconds after the the starting windows screen comes up I get and IE error "The procedure point CoRegisterInitalazeShy could not be located in dynamic link library ole32.dll." I acknowledged the MSG, then the computer continues loading until it gets to the desktop and stops, no icons, no start menu, no task bar just the picture is the only thing that loads any button I try does nothing, but if I right click on the desk an mash alt , ctrl, and delete, the task box will come up., I can get to the run new program there or actually any where in my computer but ever time i try to introduce a fix I'm stopped dead, with the same IE error MSG "The procedure point CoRegisterInitalazeShy could not be located in dynamic link library ole32.dll.", please someone out there HELP!
