Windows 10 64 bit guest, randomly restarts

I'm running a windows 10 guest on an osx host (10.12.3) and the guest os keeps crashing every now and then. occasionally running into BSOD which shows "system service error"
I tried fiddling with the vbox settings like using hyper-v in acceleration and assigning 1cpu (instead of the default 2CPU's), disabling audio, but to no avail.

I should probably mention that even though I've allocated 3gigs of 6gb of total ram to the guest os, my hardware's pretty weak (2.26 GHz and a 256display memory)

If someone could please take a look at my log file and give some insight,
thanks

You're coming close to exhausting all of the host's free RAM. I think you should not allocate more than 2048MB RAM to this VM.

I'm not familiar with this error. It seems to be caused by the guest using a newish CPU instruction. In which case there should be nothing random about the crash - as soon as you hit the code, it should crash. I don't know Mac models - is yours an old one?

yes it's pretty old, macbook unibody late 2009 model

About the RAM: 3794 - (3072 + 128 + overhead) = not enough left on your host. I have my Win10x64 running comfortably with 2048 MB, just like mpack suggested. If you really want to have that amount of memory to your guest, then close a couple of applications in the host.

00:00:03.394704   Path      <string>  = "/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso" (cb=67)

You should remove the Guest Addition CD from the VM once you're done installing them, which you have. Otherwise you're going to have problems in the next upgrade. BTW, since you have them installed, you should also enable 2D and 3D acceleration in your VM Settings.

Of course that's not your problem. As mpack said, this is your problem:

00:00:02.681351 OS Product: Darwin
00:00:03.098169 Guest OS type: 'Windows10_64'
00:00:04.389979 Full Name: "Intel(R) Core(TM)2 Duo CPU     P7550  @ 2.26GHz"
00:06:13.985110 !!         VCPU0: Guru Meditation -5300 (VERR_IEM_INSTR_NOT_IMPLEMENTED)

Combination of: OSX host + Core2 Duo + (Win>7) => Guru Meditation. This is due to the fact that 1) your computer is old and 2) VirtualBox has not implemented yet a workaround for a missing instruction: stmxcsr.

See https://www.virtualbox.org/ticket/15801. There are some potential workarounds, but not something definitive. I wouldn't hold my breath. But, I would add my logs, mainly so that you subscribe to the ticket in case there's an update.

Thanks guys, I'll just downgrade to a windows 7 32bit. I started using vbox in the first place was to have a platform for using Primavera 16.2 (which I've been introduced to just recently)
Anyway, I understand that it works just as well on a windows 7
Thanks for your time n effort y'all

Maybe it's the same problem that caused me to downgrade VirtualBox - not Windows.

Sorry for the late reply,
I downgraded to win 7 32bit, took all of the advice mentioned above (limited ram allocation, eject guest addtions), and voila! Haven't had a crash since.
I'm using the latest vbox version (5.1.14)

Thanks guys, you've been a big help.
