|This is driving me insane...|
A long time ago I got an ASUS P2B motherboard (I hate these things more than words can describe; single most unreliable board I've ever used in my life) for free (and now you see why I got it).
Matched it with a 333MHz Celeron, however much RAM I had, a hard drive video card and all that. Friend wanted it, bought it for $30 or something like that. Fantastic.
Then he calls me up and says it just randomly reboots for no reason. I of course give him his cash back and he gives me the computer. At seemingly random intervals, it would just randomly power off and run the POST again. Then, after booting again, just shut off again and over and over and over.
I tossed it in the extra parts bin and promised myself I'd destroy it.
Fast forward to now, I'm trying to turn it into cash again. While it's gone through many other uses since, the exact same CPU is installed in it again. New RAM (128mb PC100, used reliably in other systems). An old PSU - but not the same one used with this board in the past. 20GB WD hdd. 4x toshiba cdrom.
I had this thing running for over an hour non-stop earlier. I installed Win2000...I let it run. I got on the internet. I did stuff, and it sat idle for a combined period of at least 45 mins. No issues
It's spread out on my desk since I don't have a case for it yet (don't want to invest if I can't get a return on it). I repositioned it slightly.
Now, I turn it on, and it'll get halfway through the 2000 loading bar, and then boom...the spontaneous hard reboot (no BSOD before either). It will do this in approximately the same point during the loading bar every time.
Safe mode, it loads windows, gets to the bar where it does such things as "preparing network connections", "loading personal settings" and the like, and it'll reboot then.
I've reseated all of the hardware twice, same results, but it seems to do it two notches later on the loading bar? I have no clue the relevance of that but it made a difference.
Funny thing is, if I boot to the Win2k CD (which takes much longer than booting OS itself due to 4x CDROM), it runs reliably during that. I just don't want to reinstall OS to find it does this yet again.
Any suggestions? Anything at all? lol
My own knowledge and research suggest PSU...but it did it with another PSU in the past, and on top of that, it isn't "random"...it happens at the same general interval every time.
