Sonar X3 soundcard crash when bouncing and bussing

Hello,
 
I have two bass audio tracks I recorded simultaneously, one distorted, one clean. I set the send levels on each bass track to -8 and 0 respectively, and sent that signal to a bass buss I created. On the bass buss, I have compression, limiter, EQ. I want to now bounce that audio from the bass buss to a new track. I selected the original two bass audio tracks, bounce to bus tracks with the source category as buses. But, when the new audio files show up in my mixer tracks, upon playing them, my sound card crashes via making either no sound, or popping/squealing/distortion, etc.
 
The same occurs if I omit the bus and just bounce the two into one and add the comp, lim, and EQ on the new bounced track.
 
It also does it when I select all the channels on EZ Drummer and try to bounce them to one track.
 
I'm running Win 7, Sonar X3 with the latest E update, intel core i7-3770 CPU @3.40 GHz, 16GB memory, 64 bit OS. I'm going through a Scarlett 2i2 into desk mounted speakers, and using that as the in/out on Sonar. (Though the same problem happens with my IK Stealth Pedal). Audio driver is maxed at 10ms buffer via settings, sample rate 44100.
 
Not sure what else I can do to stop the crashing. I'm getting to where I'm trying to mix/master this thing, and would like to eventually use the same setup to play out live.
 
Thank you in advance for any feedback.
 
 
 
 
 
 

Thanks for the reply,

T-Racks for classic eq, quad comp, and quad lim plugins. Amplitube for guitar/bass sounds, EZ Mix for drum effects and EZ Drummer.

I bounce mostly as I'm reading on what to do during the mixing/ mastering process since this is my first go around, and that's what I read to do. I figured it should be powerful enough but the hangups I've had made me question it.

I would eventually like to be able to play out solo with this system backing me and be able to send seperate signals to the house for venue mixing (bass, kick, snare, backing vox, etc) along with MIDI controlled lights, so I was hoping to have something more simple down the line with only a few tracks as opposed to the numbers i have now.

You must have some kind of bottleneck going on or some other problem. Your computer should be able to handle much more than that. Are you using ASIO drivers? Have you tried another usb port and cable? I would think you should be able to raise your buffer size more than 10ms for bouncing and playback.
