Comp Issues and SATA Question?

[ruin97140]

okay so I just did a fresh install with new RAM and a new sound card and new speakers, which isnt prob giving this problem, but figured might as well check, so I got everything put in, got it booted running fine, stress test going for 24 hours on prime95 and everyhing with OCing, but I am using the NVRAID controller instead of the Sil on my asus a8n-sli Deluxe, since I heard they are faster... anyways, benchmarks come out better or about par to most I have seen in reviews of the hardware at stock and OC speeds... but my OS its weird ill be clicking around alot doing stuff, then my start menu will click down but, pause till it shows up, and same with closing or min. windows... its weird... I am trying to figure out whats up with it, like one thing that it does it everytime, is when I have ASUS probe open then close it, then go to click over at my start menu it just pauses up with it clicked down then displays? so any ideas? I was reading up on things, trying diffrent timings and such, and nothing seems to work... then tried reading up, and found things about SATA, and read about clusters and stripe size? I checked my stripe size and it was 64k didnt know if that might be something that could be making a diffrence, since the switch in SATA controllers, but if not, any explanation on running the so called "optimal" on that would be helpful, here is my setup
