ARGGGGH!

Now that I got that out of my system... it seems something has gone sour on my none-to-old SFF. When I built it, I tested and stabilized my OC and it has been performing pretty much flawlessly ever since. I had a few occasions when I'd get a hard lockup, usually exiting from a 3D application like a game, but that was about it. And then today happened.

Upon exiting from a game it locked up again, ctrl-alt-del didn't work so I did what I normally do and just threw the power. Waited a bit, and turned it back on. Now the POST screen has slowed to crawl. It only gets to listing the proc... not even the memory test, and just hangs there. Turned it off and on a few times, same thing happens.

One time I left it alone for a bit and it came to the Windows Login screen, but as soon as I clicked my name and actually got into windows, it rebooted itself. Hasn't done that again since.

What the hell could this be? I was thinking heat, but even after leaving it cold for 30m or so, no change.
 
The first thing that I would do is get a multimeter and check the power suply voltages. Make sure things are getting accuarte clean power. :)
 
I have a multimeter but I really don't know how to go about testing it. Is there a tutorial somewhere?
 
Thanks. Good tutorial, but as it turns out my multimeter is not sensitive enough for accurate readings. Guess I'll go with plan B and RMA the power supply? I heard these Enermax Liberty 620s had some problems...
 
You could try. Enermax might tell you its not there problem though if you arent for sure its a PSU problem. You could try swaping in another PSU, if you have one, and see if that corrects the problem before RMA'ing it.

Use a scope and see how much crap is getting through the VRM filtering;)
