Problems Upgrading CPU With Vista 64

I upgraged my computer from an Athlon 64 5200 (two cores) to a Phenom 9850 (4 cores) on an Asus M2N-SLI Deluxe motherbboard. The physical upgrade went smoothly by dealing with Vista 64 is another srory!

I did this upgrade on the version of Vista 64 that I used with my old processor. After the upgrade Vista only recognized two cores. I had to enable HAL on the advanced startup menu for all four cores to be recognized. The change in processors also caused a problem with the Windows Media Player DRM and I had to delete the DRM files to get the media player to work properly. The error message that Microsoft displays was of no help in fixing the problem. Also the upgrade messed up my TV tuner (ATI) drivers. I had to do a repair install of Vista to get it working again. Without google I would not have been able to resolve these problems.

I really did not expect these problems with Vista 64 by just changing the processor. I also which Microsoft could design better error messages that can be actually used!

Unfortunately most of microsoft's error messages are general messages and of no help at all.
As far as vista, your best bet would be to just do a full restore of your system. With the introduction of vista, and like the Xbox 360, the DRM and some OS files are hardware bound, same with some drivers. So, when you change the hardware you get an instant error. In the end, when you replace the CPU or the motherboard you WILL encounter problems, hands down. Again, best bet is to completely reinstall vista so its hardware IDs will be straight again.

Hope that helps.

I recently changed my CPU Dual for a Quad, but that was with 32bit ULT.

Just lifted out the old one and inserted new Quad, booted up and no problem, smooth as silk all cores recognised.

Looks like its a conflict with 64bit

PS..Intel CPU

I love my 64 bit os, but when It comes to stuff like this, it makes me wonder.... I guess as time goes on and x64 becomes the standard, we will see fewer of these issues. I did the same with my 32 and no issues, but my 64 gets ancy when I start messing with hardware.
