Sleep mode is really difficult for drivers to handle properly, they tend to come back up in somewhat random order, and often dependencies that were resolved in the initial startup aren't properly resolved exiting sleep.
Lots of drivers have this issue, it's not even all that uncommon for machines not to come out of sleep at all.

There is nothing easy about developing a working kernel level device driver for windows, and while the mach driver isn't perfect it does work.

Yeah modern processors will get so hot touching the heat sink will burn you.
under no load the processor is pushing ~50 degrees C and they won't shut down until they are over 80 degrees C
That's why I said load up a temperature monitor and check what the actual temperature is.

If it's the CPU overheating it will most likely restart.
What will usually happen is windows will blue screen with some random error and the default behavior is to immediately reboot.

If you believe it's the CPU overheating, I'd put thermal paste between the CPU and the HeatSink.
But I'm suspicious that it's taking 2 hours to shutdown, usually thermal problems are pretty immediate when under any significant CPU load.
As I said above I would verify what the issue is.

There are a whole host of other things that could cause a reboot, from PSU problems to RAM and bad components on the MB.

General Mach Discussion / Re: quick question about the demo version of Mach

In my case I generated the code from a wizard, so that might have something to do with it.

You should be aware of what the demo version does if you exceed the 500 line limit.
It still runs the code, but turns every command after the 500th line to a G1 move to safe Z, this is a bit disconcerting if you happen to be in relative mode when it happens, since the head keeps moving up until it hits the top of the column or the stop.

Took me a month to bother upgrading, just check the end of your program and make sure it's what you expect before you run it.

General Mach Discussion / Re: Windows shutdown driver hang
« on: September 07, 2011, 04:48:31 PM »
There is nothing else on my machine except Mac, which is why I always assumed it was the mach driver.
I built the machine installed XP Pro, installed Mach and put it in the garage.
Not a big deal just a reference point.

FWIW Even after exiting Mach, I commonly (maybe 1 in 4) can't shutdown XP because of some driver preventing a shutdown, end up having to hold the power switch down.
I've always assumed it's the mach driver, but I haven't verified.

I'd load up one of the temperature monitoring apps and verify that the CPU overheating is actually the issue.
Heat sinks will get hot even in normal operation.

Did you put thermal paste on before remounting the heat sink?

The reset could be any number of things.

No idea if this will help, but I had 2 issues when I made the transition, the first was not realizing that valid port numbers started at 1, and they all defaulted to 0.
The second was that for some reason the default acceleration setting in the motor tuning which was stupidly high stalling my steppers instantly, I actually moved the settings over from the EMC2 xml file and it still wouldn't jog until I drastically reduced the acceleration. I suspect EMC is using a different shaped ramp.

General Mach Discussion / Re: Damaging Geckodrives G540

I've been turning the handles on my steppers for going on 2 years with nothing but the E Stop pressed and I've yet to damage my G540.
