Hello, I started my pc under windows XP and after the Welcoming screen it restarted continousely. I made few search to reach a conclusion that it 'might' be the kernel32.dll missing or damaged: So, I followed instructions. Restarting my computer 'error loading operating system': made again few search and used all the tools my time and my connection can get: WD tools verified the integrity of my HD. Ok, I decided to do the same routine basic way to make it work. Deleted all partitions; formatted all partitions; Option I: installed windows 98 - done well. Put my bootable windows XP Cd and ran it: After copying the needed files and on reboot, my pc halts on Verifying DMA pool!!! Option II: redeleted all partitions; reformated Installed windows 98 - done well Installing windows XP on a new partition and after copying the needed files and on reboot - SAME RESULT - my pc halts on Verifying DMA pool!! I did this procedure on one million PC and never had this problem. I am really stuck!!!!!!!!!! Pls advise. Thank you
