Greetings Opus200, Firstly, let me tell you how much you amaze me time and time again!! I followed your XP Tweak Guide quite carefully the other night and proceded to change a number of things. My problem is this, for some reason my CPU Usage keeps shooting up and down (also indicated by the Windows Task Manager). For example, I surfed the net this evening while playing a .wav file in WinAmp. The track kept on making popping noises and the track skipped quite a bit any time I opened a new link, or scrolled down a web page. It was essentially coresponding to the CPU usgage % shooting up and down rapidly on the Task Manager. I have a feeling that I may have tweaked something the wrong way somewhere along the line and now my system (ram 512MB) can't handle simple tasks as easily. Am I way off base here??! I have a P3 900MHz, it runs pretty bare bones except my audio software, the internet and a bunch of crap attatched to it!! If you have any ideas, I would be greatful... Regards, mIchAEl P.S. I also just got a... "DAE ERROR - 9060 was encouter" while working in Protools LE (Mbox), for the first time. Any relation?
