I have a dell optiplex 330 with windows xp pro loaded but I can't get beyond the logon to windows box. This comp was previously used as a server unit for a specialised software. The software writer retained control of the software by having a dedicated server unit to which he had remote access even though the company owned the copy of the software. We bought the assets of the company (including the software) but fell out withthe writer because he hadn't been paid for service contract by the old company. We demounted the comp from the dsl access and I now want to load a fresh copy of xp pro but cannot get into the system to open the cd from within. So I tried booting direct from the dvdrom but got the bsod with many 0's 7B. I can't find what 7B is telling me is wrong b ut I can and have done a diagnostic from the setup screen which shows no errors at all. I have tried also resetting factory defaults and all the password screens say there are no passwords set. I'm stuck any clues please?
