Onboard networking chip (not a soundcard). You're in ACPI mode so they may or may not be sharing at the hardware level. Before moving the card again though, go into your BIOS again and make sure you have anything unnecessary disabled (parallel, serial, floppy if you don't have one etc). After that (or if you've already done that) find the 'reset ESCD data' option and use it, then save & reboot. That will clear the information stored for IRQ sharing and you may get different sharing on reboot. If that doesn't work you can try moving the card again.

but my old cpu was a Pentium 4 too and never happens this kind of things....the diference is just more 800 mhz

It's easy to test. Unplug the keyboard, work in your project for about an hour. If it hasn't crashed, you identified the problem & know the solutions from this thread. If it does crash then it's something else, and you've eliminated a possibility. It's been crashing on you while working anyway it seems like...just remember to save frequently and protect your monitors.

Most importantly, when you test I would test each thing at a time. Or better yet, unplug the keyboard for now and work on the IRQ sharing. When you can successfully run a Scope+Cubase project without crashing, try hooking the keyboard back up and see if the crashing returns.

You'd also have to insure that you've got the thing properly mounted, using proper amounts of decent thermal paste and a cooler that's adequate for the new cpu etc etc.

I still have this thought though...I have *never* been able to get Scope fully stable with hyperthreading active and a synth that uses active sensing. It will eventually cause the whole thing to fall over, and in ways that are not clearly understandable. My solution was just to not connect synths with active sensing to scope, use a USB midi i/o instead and reserve Scope's midi for a control surface or another synth/controller.

You can try disabling hyperthreading in your bios to see if that helps too.
