Re-installing an OS after an upgrade - A must?

I've upgraded from an Athlon XP 1500+ (Palomino) @ A7V266 to an Athlon XP 2500+ (Barton) @ GA-7N400 Pro2.

I've ran several benchmarks (3dmark01, 03) and noticed one strange thing: in 3dmark01 I've LOST performance in the Game Test 4 - Nature.

Then I noticed that when 3dmark01 starts, the spash-screen shows the "Athlon" logo, NOT the "Athlon XP" as it used to do.

Could it be that WinXP can't see such stuff as SSE or 3DNOW on the new CPU? Do I need to reinstall WinXP or maybe install SP1?

  1. You probably should re-install yes.

    Some day I'll be rich and famous for inventing a device that allows you to stab people in the face over the internet.
  2. Nope!Just delete the devices which have been marked unable to work properly.Then everything will be better.
  3. Well, the problem is that I have no problems with devices - everything works properly. I just suspect that 3DMARK2001 is unable to see that I've got an Athlon XP and not just Athlon.

  4. While there might be other solutions for solving this problem, formating and re-installing your OS is actually the easier solution of all, and most probably the solution with the best results.

    So format your HDD, install WinXP, the drivers that came with your motherboard, graphics card and other hardware, SP1 and all other critical updates and then the rest of your software.
