Any help would be appreciated. Here is my scenario: I have a NEC AMDK62 computer with at 500mhz. I have upgraded my sound card to an audiophile 2496. I also have 192 ram. Unfortunately the computer is being used for other purposes as well as recording. I regularly defragment the hard drive and do the other assorted tricks I have learnt from this page and other sources. I was told my hard drive speed should be upgraded to 7200rpm but my computer will only recognize it at 4200rpm because of something to do with my mother board. I have been recording at 24 bits with new card and have to go to 16 bit instead because of major drop out problems . Even at 16 bit I'm having problems more so than the original sound card. I can't seem to use any effects without drop outs. Desperately needing an answer. Thanks Gag
