First, thanks for looking at my thread.

So this is the problem:

This isn’t my computer, but unfortunately I am the most ‘tech savvy’ person around this place so the chore gets shoved onto my shoulders when it comes to fixing things. Words of the user, “The PC was working fine; suddenly the dang thing starts going into hibernate/shutting off every now and then.” User tinkers with power management settings, things seem to be fine for a couple days. User returns after lunch today and PC is off; won’t turn on. Calls me in. I go through very general troubleshooting steps and what we end up with is the PSU fan does not spin during any part of the boot, green mobo LED is on, CPU cooling fan has power, NO display or response from keyboard/mouse.

System specs

Windows 2000
Asus p4sp-mx se motherboard
Phoenix D686 BIOS
Processor: P4
RAM: 512 MB DIMM
PSU: 230W (cringes…) ViewTech model VP-500

The POST boot occasionally (i.e. when I first give the machine power the LED’s light up power to CPU fan, but no POST boot beeps, when I flip the PSU pw switch and it boots I get the POST beeps) it gives me continuous individual long sustained beeps 1-1-1-1-1-1-1 etc. I tried looking up the beep code list for phoenix BIOS but those didn’t seem to match with any of the initial results I received. The pw_switch doesn’t seem to respond but the reset button works fine. There are other functioning computers here, I could swap PSU’s to narrow things down, but out of curiosity of learning more about hardware I prefer coming here and asking more experienced people on what should be my course of action.

Any suggestions would be greatly appreciated. I’m slightly above average as far as computer usage goes, but that probably isn’t saying much. I realize PSU problems are the #1 hardware issues and the fact I’m asking for help shows I really don’t know anything. However, be as technical as you want in your explanations; I’m here to learn from experience.

Whenever someone has time to get around to this, thanks!
