Please, any suggestions welcome!
I just put together a new recording PC:
Win7/64 Core i5, Zotac motherboard (Intel H61 chipset).
Star Tech PCI1394MP firewire card.
Nuendo 4 software
StudioLive 16.4.2

I'm very computer savvy, and this one I think must be a hardware issue, but its still a little odd.

I'll be connected to my StudioLive, recording in Nuendo, playing stuff back, and out of the blue the machine will hard lock instantly. No mouse, keyboard, nothing. No bluescreen, no errors. I have to hard-power-off the machine to reboot it. After rebooting, I've checked all the system logs and can't find ANYTHING logged at the time of lockup or just before it. I've even tried disconnecting the StudioLive cable while it's locked up and I still can't get it to come back to me.

I've tried using the TI 1394 driver, and the Legacy OHCI 1394 driver, no difference.
I am suspecting RAM or hard-drive issue to cause it. But, I've been using that same hard drive as an external drive for months with no issues, so I'm suspecting more RAM being the problem. BUT, if I never launch Nuendo, I can use the PC all day long, play video games, office apps, whatever, and I've never seen it hard-lock like that. Only when I open Nuendo, and start to play back a multi-track project through the StudioLive.

Has anybody experienced anything like this?
Any suggestions welcome. I have another machine with "extra" RAM that I intend to try out next week, but I really need to get to the bottom of this.

Greetings,

The setup you describe appears to be workable. I have something sort of similar and it has been running for a couple of years with no problems. I am guessing that you may be on the right track with RAM. The other thing to consider is shared interrupts. If the firewire interface is sharing with something else, that may be the source of the problem. If not for the video games, I would suggest that the power supply may not be adequate. I have had similar behavior related to high powered video cards on CAD systems, but gaming is pretty taxing so I doubt that is happening here.

Best of luck with this. It is an odd one.

Regards,
Milton Davis

Thanks Miltondavis, I guess I have not really "game tested" the system. I was only playing 1980's MAME games... haha.. I don't think that counts.
My point to that was just that the computer can be used for other stuff for long periods of time, and hasn't shown any other lockup symptoms. It seems that when I playback a multi-track project in Nuendo on the StudioLive, I am rolling the dice each time and sometimes it just completely locks up.

I haven't checked for shared interrupts, but how exactly would you "un-share" an interrupt in Win7 w/PCI? I think it's all hardware-based and I don't know that there's many options for it.. The motherboard has only two PCI slots for the firewire card. I'm not sure that I've tried the other slot, but I will try that as well. I have already completely "stripped" the PC and disabled everything that isn't being used, including the network port. I have also stripped down all Windows services so there's no automatic scheduling services running, no auto updates, or any other non-essential background monitoring services.

Depending upon what is sharing you simply right click and disable it.

I tried 3 things:
Moved 1394 PCI card to other slot
Tried completely different RAM
Check Dev Mgr

In Dev Mgr, it was sharing IRQ with two things, one is a USB host, the other was a system component, so I left them alone.

I restarted and played around in Nuendo, within 5 minutes it hard locked up.

I then started poking around the BIOS looking for ANYTHING. I found the SATA hard drive mode was set to IDE emulation instead of AHCI. I don't really know if that affects anything serious in Win7 or not, but I changed it to AHCI (you have to first change a reg key before changing the BIOS otherwise it will not boot), so now it's running in AHCI mode and AHCI drivers in Windows.

I played around some more in Nuendo, and I was able to use it for about 40 minutes without a lockup.
It doesnt' mean anything to me YET because I've successfully used it for periods of up to 2 hours without lockups so far.

I can tell you this, that it seems that EVERY time it locks up, it is when Nuendo goes to start playback. The timeline cursor moves for a second and stops and the whole PC is locked. This seems to be the recurring symptom. It can happen in any project at any timeline point. I have seen no other clues.

But, this AHCI mode is interesting. I don't know if it will solve anything, and I have my doubts. I would imagine that if it were really a hard drive/bus issue that I would still get an event log error or a blue screen.

You probably should disable that USB bus. It may be the entire cause.
