Hey, all...i have been a lurker for some time, and, I dont think there is enough hours in the day to be spent learning from you guys here. I have always had answers to my questions by doing searches from previous people like me, but, i am stuck with this one. I recently upgraded my MOBO from a jetway with a via chipset to an ASUS with an intel chipset. I have a P4 3.2 chip with 3 gigs of ddr 400 Ram, 2 X 160 gig IDE harddisks, running nuendo 3.1 and various plugs, and apps, UAD-1, with most of their plugs while, my system, is way more stable, and effeicnent with this new setup I do have one problem. My CPU spikes up and down alot. for example, when i load up a track, it could be at like 10%, and then when i start playing the track, it will jump all over the place. any ideas? i have optimized the system, and started from scratch with the new mobo, reformatted the main programs disk, and did fresh installs of everything. This is the only problem, i didnt have with the old setup. please help.
