Windows 7: Search Index "Windows explorer has stopped working" error

Hello,
I problem I have been geting in the past 2 days is that whenever I use the search index, like for example look in my librarys, program files, or look for anything on my computer, a box pops up saying "Windows explorer has stopped working", and whatever im searching for will automaticaly close. This is very frustrating because like everyone who owns a PC I search for files and such, and I have tried many things to try and fix this, including:

-System restore
-Uninstalling windows updates
-Restarting computer
-Disabeling Index service
-Disabeling Windows search service

I have read of a solution to this problem that involves deleting files related to the index, but again I cannot do this because every time I look in search index it automaticaly closes.

Any help on this issue would be greatly appreciated

Try to do system file check first:
Start-->cmd (run as administrator)-->sfc /scannow (space between sfc and /)

If it does not work
Try a scan disk.
Disk Check

If it doesn't work, you might want to do a Repair Install , it will preserve your data, user account, and system driver

Thanks I will try sfc/ scannow.
