Strange things are afoot with my computer. Here’s the deal. I went on vacation, came back, and my computer was acting all weird: it would POST but fail to load the OS, sometimes fail to POST, bunch of weird stuff. The mobo, an Epox EP-9NPAJ, gave an error code, which, according to the support site, was Very Bad.
That’s odd, I thought, I wonder what happened over my vacation, but hey, I’ll just get a new motherboard. I buy an Asus A8n SLI Premium. I hook it all up, the onboard power LED lights up, press the power button, but nothing happens. Fans don’t spin or nothing. I take it out of the chassis, leave only the video card, one DIMM, and the processor, hook the power up, and do the little thing in which I touch a paper clip to the two prongs that attach to the power button, and everything works fine.
I turn it off and try again. I keep touching the prongs, but nothing immediately happens… after a minute or two of fiddling, it turns on again.
I return the mobo to the chassis, try again by connecting the power button, it doesn’t work-- power LED on, but fans won’t spin, won’t POST. Again with the paperclip, it takes a little fiddling, but it starts once. Hm… maybe a bad power switch? I try the paperclip again, fiddle around, bu it just won’t go again.
I’m extremely puzzled here. Can anyone suggest what might be wrong here? Could this be a power supply problem? (It is an Antex 400W that is just about a year old… seems kinda soon for a failure?)
