Hello Gems,
Right now, your Compaq (HP) computer has a Volume Licensing edition of XP Pro installed (Line 10), and that installation was done with an Invalid Volume Licensing Key. Invalid VLKs are generated by pirating programs called "key generators" (keygen for short) that are designed to mimic the same formula that Microsoft uses to generate genuine Porduct Keys. However, since the Product Key is pirated and not generated by Microsoft, it is Invalid.
If you search the internet for the part of the VLK reported by the mgadiag utility, DHFYG-YCDB3-BCJPJ, you will see that there are over 20 pages of hits posting that same Invalid VLK.
As a rule, VL editions of XP should not be sold to individual consumers. Businesses, schools and gov'ts normally use VL editions for flexibility in installing many computers. Also, Volume Licenses are Upgrade Licenses only and cannot be sued as original or base licenses on a new computer.
This is why you were seeing the "software counterfeiting" messages on your computer, because the current installation of XP is an unauthorized installation.
Look on the computer or in the materials that came with your computer to see if you have a Certificate of Authenticity (CoA). If you have one, tell us about the CoA. Tell us:
1. What edition of Windows XP is it for, Home, Pro, or Media Center?
2. Does it read "OEM Software" or "OEM Product" in black lettering?
3. Or, does it have the computer manufacturer's name in black lettering? We would expect it to read Compaq or HPQ.
4. DO NOT post the full Product Key that may be on the CoA.

If there is a CoA on your Compaq, luckily, the solution to your XP problem is simple. Use the recovery solution supplied by Compaq to replace the nongenuine installation of XP Pro with the genuine original installation of XP which was on your computer when you purchased it new. The edition of XP that came on the computer will be printed on the Certificate of Authenticity affixed to the computer's case/chassis. Be sure to back up and offload your data before you do this because typically the recovery process destroys all data on the hard disk.
If you do not have the Recovery CD supplied by Compaq, you can order Recovery CDs for many Compaq/HP models directly from Compaq/HP. If Recovery CDs are not available from HP, try http://www.restoredisks.com
