OK. so i have a Velocity tower with a P5N-E SLI board in it. it came with vista but me being an xp lover went and got XP pro 64-bit and replaced the OS. like 2 years went by and i had USB 2.0 my hard drive died so i went to reinstall XP 64-bit on a new drive. everything was going to plan...or was it lol. i ran all the drivers i had and even updated them. BUT it has become a slow slug of a pc! and the USB 2.0 is now GONE 1.1 only. i dont know what i did wrong but im sure it has something to do with the mother board. i plug in a simple ex hard drive and even with SP2 it says it can run faster. then it crawls to a halt until i unplug the drive. i dont know what i did wrong. anything come to mind with you guys? im out of ideas haha.
