Sonar Producer 8.5 is crashing with no error

I had been running Sonar 8.5 Producer with no issue.  I decided to upgrade my computer hardware and now Sonar crashes all the time.
 
My system:
AMD Phenom II 3.2 GHz Quad Core
MSI 870A-G54 Motherboard
NVidia GeForce 8600 GT
4 GB of RAM
Windows 7 Professional (32 bit)
EIDE Hard Drives
AKAI MPK25 midi keyboard
Sound cards: I have tried M-Audio Firewire 410 and E-MU 1820 running ASIO driver mode in Sonar
I unplugged all USB devices to try and issolate the problem
 
Before I upgraded my computer hardware, my system config was:
AMD Athlon 3500+ 2.2 GHZ
Asus Motherboard
NVidia GeForce 8600 GT
2 GB of RAM
Windows 7 Professional (32 bit)
EIDI Hard Drives
AKAI MPK25 midi keyboard
E-MU 1820 sound card running ASIO driver mode in Sonar
 
The old configuration worked fine.  Never crashed!  The new configuration is very unstable.
I'm starting to think that Sonar 8.5 is not compatible with my new MB and AMD Phenom II CPU. 
Yesterday I formated my HD and reloaded Windows 7 to rule out any conflicst with other software.  After installing Windows 7 I loaded up the E-MU 1820 sound card drivers.  After I got that working, I installed Sonar 8.5 Producer.  I started a test project and loaded up a couple of loops.  I pressed the spacebar to start playing and after a few seconds I pressed spacebar to stop.  Sonar crashed as soon as I hit the spacebar.  The audio stops playing, but Sonar stops responding.  This is the exact issue that I have been having with Sonar ever since I upgraded my hardware. 
I ran Windows Memory Diagnostics  to test my RAM chips and no problems were detected.  Before I whiped my system, I was running StarCraft on this machine with no issues.  Starcraft is resource intensive and the system handled it just fine.
I'm using ASIO drivers. 
 
I am out of ideas.  Let me know if you have anything I can try.
Thank you!

Thanks for the tip.  I'll  let MemTest86 run tonight. 
I am running a 32 bit version of Windows 7.  I'll update my post to make that clear. 
Thanks for your help!

I'd 1st recommend running "Prime95" to check if your system/hardware is working correctly.

I'm starting to think that Sonar 8.5 is not compatible with my new MB and AMD Phenom II CPU. 

Yuor looking in the worng place. Try looking at your hardwareand it compatabilty with your new upgrades. Soanr works fine with  AMD phenom and Sonar doesnt care about mobo. Any decent modo will run sonar.
 
Look at your hardware!!

Firefox has a built in spell checker and it's free. It automatically spell checks as you type so you don't have to click on that pesky spell check icon.

Thanks for the tip guys.  I'll try Prime95 when I get home tonight.  I'm glad no one is having problems with the Phenom chip. I'm really happy with it and don't want to get rid of it.

I'll post the results of my test tonight.
Thanks!

I only used there A hole checker and guess who it flagded? (Insering no smileys)

Spoken like a true professional.

Just updated video drivers.  Rebooted system.  Started up Sonar. Opened a project and worked on it for a little while before it crashed.

After Sonar crashes, I open up Task Manager and it tells me that Sonar is not responding.  I can see process SONARPDR.exe and the it is taking up CPU cycles.  Between 5 and 6 cycles.  I right click on the process and select "End Process".  This causes Sonar to close but the process remains in the list of processes.   However, the process is no longer using CPU cycles.  I then select it again and select "End Process Tree".  This causes the process SONARPDR.exe to end and it is removed from the list.  I can then reopen Sonar normally.  However, I normally reboot before trying it again. 

Anyone have any other ideas?

The SONAR process hanging is sometimes indicative of a MIDI device not allowing SONAR to close. I notice you have an AKAI MPK Keyboard attached. Ytr diconnecting it and seeing how SONAR behaves.

Have you tried lowering or raising your ASIO buffers?

Does you system run unstable with the Firewire or USB sound card or either. Don't connect both?

Do you know what Direwire Chipset you are running? I'm assuming its on your Mother board

More questions to come but that will do for now.

I'll chime in for a bump....

And underscore what mudgel says.
I'm still on SPE 5.0 and use the Opcode 8port SE...yes, still works flawlessly.
I have to turn on my midi rack power strip or Sonar won't open at all.
If I forget and open Sonar it hangs....as soon as I turn on the midi power strip it open asap.
I guess some other hardware device may cause a similar problem.

EDIT: just realized that maybe my response was not as applicable as I thought....I need more coffee.

Hope you find the culprit.

have a look at what your sharing IRQ wise, that might hold some clues.. I turn off my network card on my AMD machine.. otherwise it messes up the timing.

you have run the rego thing in ccleaner? see if you have anything left that shouldn't be there

but there are logs (maybe silent ones that aren't displayed) that need looking at

I would contact tech support also, maybe they can find out something. Since what part of what you paid for was support

I found the problem!!!!
It turns out the problem was caused by a combination of motherboard and brand of RAM.  I learned that the MSI 870A-G54 Motherboard has stability problems with Corsair RAM. 
The problem was extremely hard to troubleshoot because the RAM didn't show any issues when I ran MEMTest86 and Prime95.  However, a few days ago, I started getting errors in other programs and my machine started bluescreening.  I ran MEMTest86 and this time it found errors right away.  I took the RAM back to Fry's and they told me that lots of customers have been having stability issues with this RAM when using the MSI 870 motherboard.  It is also unstable with some Asus boards.  They recommended I go with Patriot RAM.  I swapped out the RAM and Sonar is no longer crashing!
I can finally get back to work on some projects!!!  Thanks again for your help!
