Windows 8 system locks up

[xilience]

Recently installed Win8 on my home server. It has an AMD X2 CPU, 2GB Ram, nVidia 8400GS, SATA 1 PCI card, and a bunch of disks. I've done my best to update all drivers/firmware.

For some reason, the system locks up every few days. It seems that it always happens WHILE I AM ACTIVELY USING IT. (locally or remotely) I use the system as a server so it's running all the time.

Let me clarify what I mean by the system "locking up". The screen will freeze, no input is recognized, and no network response. Even the CD tray will not respond to the hardware eject button. No BSOD or error message of any kind, just a system that is completely unresponsive.

How can I go about fixing when I have no error messages? This system worked fine with Ubuntu 12.10 Server Edition, WHS v1, and briefly Win7.

Did the event viewer have any errors reported? Might try looking there first and see if it has anything. Also what task or tasks are you doing at the time it freezes up? General web surfing, watching a movie, encoding a video ect.

Nothing stands out in the Event Viewer. (but I'll give it a more thorough check when I get home)

There is no obvious cause to the freezing. Once it happened while I was browsing files, once while resizing a window. Once wile saving a file. It just seems completely random.

Also check in Action Centre then Maintenance then Reliability History gives you a graph ,just click on the circle with white X(ones with problems) for more info.

I am somewhat reminded of the symptoms with a failing CPU core, but I would think the fact that this did not occur until Windows 8 would rule that out.

Thanks. I actually have a spare AMD X2 series CPU, so I will try and swap it out if nothing else works.
