Are you using a valid microsoft XP key?\n\n\nSearch for this error in www.microsoft.com.\n\nError code 0x80004005\nThis problem may occur if a file that the Windows Product Activation (WPA) requires is damaged or missing. This behavior occurs if one or both of the following conditions are true: • A third-party backup utility or an antivirus program interferes with the installation of Windows XP. \n• A file that WPA requires is manually modified.

if you have changed the bios to boot from the cd then you shouldn't have to do anything as the windows xp installation screen will come up automatically.

Just pop in the XP boot disk and this should get you started! But f you don't get that far, well, check the jumper and take off the little cover, that will clear the password.

Kindly disregard the previous advice, as it doesn't pertain to your problem.\n\nTo fix your problem, boot to your Windows CD and perform a "repair installation". \n\nHere are instructions, with screen shots, on how to do that:\n\nhttp://www.webtree.ca/windowsxp/repair_xp.htm#How%20to%20Repair%20Windows%20XP%20by%20Installing%20Over%20top%20of%20Existing%20Setup:\n\nNote: When you get to the page you may have to scroll to the link that says "How To Run A Repair Install"

after installing the card and restarting the PC you should see the message "new hardware detected", then follow the instructions on the screen. if you're asked for the CD then insert the XP Home disk. Maybe this is even not necessary  if the installer find an appropiate driver in the driver directory.\n\nedit:\ni forgot to mention you must be logged in as administrator

If you enter your BIOS setup, there should be two sections: one for enabling and disabling, and one for creating and changing your password(s).\n   BIOSes are different, but once you get into it, it's pretty self explainable. Just don't change anything unless you know what you are doing, but if you do make changes, there's a section at the end to reset defaults,but it is just easier not to change anything but your password preferences. To enter your BIOS, restart your machine and start hitting your delete key untill you see a message telling you that you are entering the BIOS, or just hit the delete key slowly until you see your BIOS screen. You may have to enter your current admin. password to change anything, so I hope you know your admin. password. By the way BIOS stands for "Basic Input Output System". Good luck.

Insert your xp disk, and boot from it by pressing any key upon boot.\n\nGo through all steps that you would normally go through for an install it will tell you it found a copy on windows and ask if you want to continue.\n\nPress R and it should start to repair the copy  on your computer.\n\nThis is the most valid answer to such a vague question.\nThere are many things that can cause this from corrupt system files to incompatible hardware.\n\nDon't take it to that IT person again obviously they don't know jack.

not sure...\nyou appear to have constant computer problems...\n\nif you change hardware after reinstalling xp,\nxp needs to verify alterations,or may cause errors,\nif you have two drive c:&#92; (s) check bios settings,\ncheck hard drive jumpers , verify that xp is not on both drives,\n\nrun scandisk error checker,\ncheck device manager,

If your replacement motherboard is similar to your original motherboard with respect to specifications (chipset, etc.), you may be able to get away with it.  Windows XP installations are tied to a specific hardware configuration, and if that changes significantly, you may have to re-register with Microsoft - usually by calling it in or going online.  (Microsoft Office installations are similar in that you have to re-register if something major changes.)\n\nI replaced a motherboard in a computer I had and reinstalled everything fine - the restore disks didn't detect any problems and reinstalled everything for me without a hitch.  The trick there was that my replacement was the exact same model as the original, so nothing in the new motherboard alerted my restore disks to a potential problem.\n\nAs for other software aside from Windows and Office, I don't think you should have a problem.  Most other software doesn't care if you swapped out a hard drive or added memory, unless their installation schemes are tied to hardware as well.  But as far as I know, most software doesn't have this extra security measure in place.

if it is a retail copy of XP, try contacting microsoft support, but if it is an OEM version (ie. came with the PC) you probably will have to contact the computer manufacturer or reseller.

First of all you must let all of us know what OS your are using.\nIf you are using windows XP/NT, then go to control panel and see the user accounts, you can disable password protection from there\nIf this is a BIOS password, then enter your bios setup by entering on boot screen f8 or combination of ctrl f8 .\nThis will let you in Bios Setup.\nThen go to' power on password' option and disable it from there.
