This is not a BIOS password issue. Playing game in full screen mode my PC froze. I could not get back to desktop using alt-tab or to task manager . After 45 minutes of inactivity I powered down PC and restarted. After the user selection menu and entering my password I got a dialog box entitled 'Windows Product Activation' The text inside was 'a problem is preventing windows from accurately checking the license for this computer. error code 0x8007005' Clicking on OK takes me back to the user menu, selecting either user, one password protected and one not gives the same error. No new software or hardware added recently. Genuine Windows XP Home Edition fully up to date. Had PC from new - TINY Pentium4 3GHz. Everything is on motherboard (P4M-800M/T2) apart from Video Card which is a NVIDIA GeForce 5200FX which has been fitted and working for 2 years. Problem also occurs if this is removed. Optional Information: Computer OS: Windows XP Home Browser: IE Microsoft Knowledge base does not list this error number. Starting in Safe Mode works sometimes and everything on the drive appears accessible. Starting in Safe Mode with networking requires windows license to be registered and needs to reboot in Normal mode to register. I removed the hard drive and placed in a second pc to retrieve all my documents so I could reload Windows. Chkdsk showed no fault and no virus was found. I have tried to use the provided ‘Restore’ CD but cannot as I get an error message about BIOS Lock and to consult the manufacturer (TINY) who unfortunately ceased trading shortly after I bought the PC. When booting up (boot from CD) with the repair disk in the DVD drive I see:- Phoenix AwardBIOS v6.00PG Copyright (C) 1984-2003 Version VYA18 IDE Channels 0 Master and 1 Slave show my HDD and DVD Drive respectively After the PCI device listing and Verifying DMI Pool Data...... I noticed the following on screen Boot from CD : 1. FD 1.44MB System Type-(0F) then Starting Windows Millenium Emergency Boot... I briefly get the Reload screen to access disk functions, Repair, Restore Details etc.. on the screen and then immediately the screen goes black with two lines of text. First in yellow ‘This Software is licensed to your computer manufacturer’ Then in white ‘Unable to determine BIOS lock, please contact you system manufacturer’ (The 'you' is not a typo) Pressing Esc gives a command prompt of A:\> (There is no floppy drive on the PC) Trying to change drives to HDD (C or DVD (D as a DOS command results in ‘Invalid Drive Specification’ Checking the Directory of the 'disk' A:\> shows a list of files (see below) that are obviously not on the CD and I believe must be a virtual disk on the motherboard to enable the message to be shown. (Volume Serial Number (of disk) is 28F3-B8C1) Directory of A:\ command.com test.bmp filelist font.bmp msg.txt reload.exe autoexec.bat a total of 619,196 bytes I can access the BIOS in the normal way and can change all settings. I have tried removing the BIOS battery with no success. Moving the CMOS reset jumper - When replaced in original position PC boots reporting CMOS Checksum Error – Reloading defaults. BIOS Lock problem still there. Any help or suggestions gratefully received.
Hmm.. It appears that the Windows XP activation key has been corrupted. The best way out would be to do this : 1. Take out the hard disk drive and scan it using another computer, to correct soft errors and check for bad sectors. 2. Put the hard disk drive back and boot up using the Windows XP installation CD. 3. Have the Windows XP installation routine do a repair-install... basically copying over the original files to replace any corrupted files. It also gives you the chance to reactive your Windows XP installation.
