Snow Leopard crash problems

I posted a topic yesterday (19th) about the constant crashes on my desktop Mac since I upgraded to Snow Leopard. I also included a crash report. The problems I'm experiencing appear to be similar to what many other users are reporting. I installed from scratch and I've tried all the fixes available without curing the problem. I also have a Mac book that is running absolutely perfectly with the same applications.

What seems clear to me though is that my Power Mac runs fine so long as I don't put it to sleep. So now, I switch off at night and have the 'put computer to sleep' option set to "never" and "hey presto" everything is running fine.

Clearly there is a problem, but I'm posting this in the hope that it might be helpful to the more knowing users in helping identify WHY its happening,

Power Mac & MacBook, Mac OS X (10.6.2), Power Mac Dual 2.8 - Macbook intel

... my Power Mac runs fine so long as ...

There is no PowerMac that is capable of running Snow Leopard. If you have upgraded the machine to meet system requirements (Intel processor, 1 GB RAM minimum, DVD drive), you've still got an unsupported setup if you have installed Snow Leopard on it. It wouldn't surprise me to learn that it doesn't work perfectly.

If I'm on the wrong track here, can you clarify?

Ahh, okay... that makes more sense. While I don't have any experience with what you're seeing, you may want to try [resetting the SMC|http://macosx.com/forums/howto-faqs/302002-reset-system-management-controll er-smc.html], which manages all power-related functions (including sleep).

Well, things appeared okay for a day or so, then problems started again. Always after sleep mode, applications hang and computer crashes. The only way I can avoid the problem is not to let the computer go into sleep mode. Annoying and frustrating,

I would recommend backing up all your data and doing a fresh install of Snow leopard, to eliminate any corrupt files.

The problem has been solved and it was a hardware problem. Specifically a 7 port USB hub! I suddenly experienced problems with Ilok keys not being recognized, so I changed the USB hub and since then not a sniff of a problem. It was responsible for all the issues - no more "sleep issues" leading to crashes, nothing at all, everything back to normal!

Spoke too soon, problem has persisted and even sent to apple dealer who has done all the checks on drive, memory etc but when I got the Mcc Pro home the problems continued. The ONLY thing plugged in is 30" apple monitor and apple mouse and keyboard. Back to the apple dealer on Monday!
