Aahaa, that was it. Thank for your help from Germany. The sun is shining, so do I and the pc as well.

Thanks for the hal.dll. To copy the .dll to a NTFS formatted partition was not so easy, but I managed it. The result? The pc started again and the answer was the same as before. The problem may be that XP is not on C:, its on D:. C: is formatted with Fat 32 and D: and the other partitions and drives with NTFS.

I changed the grafic cards from Matrox to Gforce 4. First I changed back to VGA, than via software I could deinstall (remove only) the matrox driver. The routine said I schould switch the pc off, what I did. I changed now the AGP cards and started the pc. Out of the sudden there is a message saying "windows root/system32/hal.dll" is missing or destroyed, however I didnt touch anything. XP Prof and it is a Standard PC configuration. Any help?
