Some of you may remember me from a few months back. I was asking for advice about building a new PC, and up until recently it's been running great. A few days ago, I was playing Fallout 2, when the computer locked up completely. I had heard of the game causing this in the past, and thought nothing of it. Just reboot and everything would be fine, right? Not so lucky. I held down the power button so it'd turn off. After it did, I pressed the power button again, just as the computer was turning itself back on for whatever reason, causing it to shut off just as soon as it began starting up. Thought it was strange, but didn't think anything of it, until I tried turning it on again, and it refused to post. I turned it off again, and let it sit for a moment before trying to reboot. Still didn't post. Tried a few more times, nothing. After nearly crapping myself thinking I had just bricked my $1,300 PC, I decided to take a look inside. I saw nothing out of the ordinary other than a few cobwebs and dust, which I cleaned out with compressed air. After plugging everything back in again, I tried starting it up one last time, and for some reason it worked. Now it has refused to post AGAIN three times within the past few days, however turning it off and on again causes it to post and start up without problems, however tonight it needed to be restarted twice before it did so. I'm worried something is dying in the damned thing, and I'd like to hear what you more experienced users have to say about this. One last thing, after it does start up, it still runs beautifully. No errors or problems of any kind, just doesn't want to post every now and then.
