O.K. I st up my computer and installed Vista Premium 64 bit. It took 16 hours to load. (Someone on the internet said theirs did the same and worked fine afterwards) I got it loaded. I Loaded new drivers from a flash drive newly copied off the internet from another compoter. It took over one our to run the driver program for my MoBo and another hour for my Graphics card. Anything I do in vista takes forever. If I click a button it takes minutes for the computer to react. I am at wits end. I checked processes being run and under the cpu with nothing happenimng it is running at an 80% load? HEEEELLLLLLP
Itakes 10-15 minutes to boot up.

Thanks in advance. Should I go buy 32 bit Vista and pour gas on this 64 bit version?

16 Hours ?????
Somethings really not right.Check the SATA Cables for your Drives,replace them and see if things improve.
Also try different SATA ports .
I dont think the issue is with Vista X64.

Also sound effects run really slow. Like the opening sounds go realllly slooooooow.

Changed Cables no better

it almost sounds like the processor cache(s) is disabled. i would reset the BIOS to defaults and go from there.

any idea what process is causing the high cpu usage?

Do as said above but also check your error logs for hd controller errors. I know this can cause big slowdowns.

Check your mobo drivers.

Check for conflicts in the device manager.

Check that your memory is not bad, if the page file is being used alot this will slow down the computer.

There is no way that after you've installed Vista 64 and try to load the first set of drivers should this take nearly an hour. I agree with the above posts, reset your BIOS and boot up again.

How have you got you HDD configured? I notice you have two.
