I have a Acer Aspire 5000 with XP home. It continually recycles through the boot up screen giving me the option of normal start, safe mode etc. None of them work. I formatted the drive and lost the partition. I tried to reload XP with the disks that came with the system and no go. I tried a full blown version of XP and it states "DMBOOTSYS" is corrupted. I have also received the error of "Shell32.dll is not valid". I have tried the Acer restore CDs, A full version of XP and a full version of WIN98. Any help would be appreciated as I have exzausted all of my ideas Thanks
