Default CPU/Motherboard problems

Hi,



I recently upgraded my motherboard and CPU. I changed my motherboard from a Asus A8N-SLI to an Asus N3N78-EH. I changed my CPU from an AMD Athlon 4600+ to an AMD Athlon 6000+. The new motherboard also necessitated a change of RAM to DDR2 (from DDR). I kept 4GB of RAM however. Everything else is as before (graphics card, sound card, hard disk, etc)

The problem is my new set-up is slower than my old one! I can only conclude that either I have set it up incorrectly or one of the new parts (CPU, Motherboard or RAM) is not working correctly.

Can anyone offer an guidance on what I can do to track down and solve the problem?

My old set up got a score of 8034 on 3dMark06 but my new upgraded version only got 5589 :-(.

Device manager reports everything working fine so I am at a loss.



thanks for any help



Jon

Need some more info before drawing any conclusions and attempting to fix it.

All important system specs, RAM timings, have you overclocked at all, what temperature your GPU and CPU are running, what kind of cooling you're using etc.

Did you reinstall Windows or are you running the same install from the old machine?

thanks for the replies. I'll post my specs tonight (is there a best place to get this info from - Bios, some diagnostic tool?).

Regarding Windows - I didn't reinstall or repair. I just detected the new hardware in my existing Windows install.

Probably just a driver issue then.

"Probably just a driver issue then. "

What do I need to do then to remedy it? Re-install windows? I installed new drivers for my motherboard from the CD that came with it.

Did you uninstall your video card drivers and reinstall the newest ones? Even though you kept the same one you changed the motherboard so it's a very good idea to either do a repair install or reinstall all drivers including things you didn't change.

Hi,

Yes I installed the drivers that came with the motherboard and reinstalled new updated ones where needed. I installed a new driver for my graphics card.

Repair Windows. Detecting the new hardware is not the same as installing the correct drivers for the devices to work. You were fortunate enough to have it boot.

Do a repair install of Windows to force the new drivers to be installed. Then it should work fine.

Thanks - I will reinstall windows. The Windows CD I have is the Computer Manufacturer's CD - is that ok or will it re-install drivers for my old motherboard that came with the computer as part of the windows install?

thanks

Jon
