Windows Media Player nor System Restore will open

[Spikeman]

 I have a Dell Dimension running Windows XP.I realized about 3 weeks ago my WMPlayer would not run.When i try to open i just get an hour glass for a few seconds and then nothing opens.My first response was to restart the computer,no help.I then thought about using system restore but alas it opens to a blank screen if at all.I feel these problems might be related to each other.Oh i also thought about Directx not being current so downloaded an update and would not install saying i have problen with a windows file cabinet ??I'm sorry dont have the exact message.Anyone familiar with these problems ???Any help would be most appreciated.Thanks

Try openning your restore system in safe mode.Restart your computer & when the windows logo comes up push the F8 tab. Put your computer in safe mode try your restore. Then you might be able to restore to an earlier date.
