In the 6 or so years I have been using and learning Cubase I have really never had issues beyond simple tweak elements that were not Cubase problems but my own. I could post this on some other forum but I have seen substantial demonstrations of broad skill and knowledge here that I have come to trust and look forward to learning from so here goes.
My new system is a Gigabyte Z68 AD3HB3 motherboard, an 850W Corsair AX power supply, 2 Crucial Solid State Drives used in RAID 1 configuration for a windows 7 boot only. My Cubase and other software is on another drive, a 2tb WD 7200 Blackand connected via 6gb Sata ports as are the SSD units. My audio monitors are spewing out noise from the mouse as it rolls across the desk, noise as the computer runs and in general just annoying spurious hiss that is driving me nuts. Particularly when I compare it to ANY of the older computers I have used from Cubase 2 SX and every upgrade until now Cubase 6. It is NOT Cubase but anytime the audio monitors are on. Clearly a power problem of some kind but I find it odd that the mouse movements are picked up in that noise.
On playback it is not varied by the volume levels, just a low level background hiss . If you are turning up the volume to a typical inside speech level, you wont really notice it but if there is nothing going on in the room, it is like the tinnitus in my head when I try to go to sleep at night.
THANKS for any thoughts…AL
