I found a solution, if this problem occurs for someone else here is the answer(at least for me).
Running win-XP Pro sp3, do the following.
Go to documents and settings\''your user name''\local settings\application data, look for the files
iconcache.db, DCBC2A71-70D8-4DAN-EHR8-E0D61DEA3FDF.index, and 2232(zerobyte-file), and delete them.
Then do a disk repair from properties at c:\. Choose automatically fix system file errors, and run it!
Restart!
This helped for me, i tried to just do the diskrepair at first but nothing changed, but after deleting those files it worked, if you're not comfortable with deleting them just rename them, but i don't think they are that important for your system, since windows doesn't recreate them after reboot.
Thanx to ''Tolle'' @ overc, for the solution!!
