ABIT IS7 Beeping?

I just got a new computer yesterday and already am wondering if I should'nt have....its an ABIT IS7 motherboard, pent4 3.2 ghz prescott, 350W power supply with 3 extra fans, one intake and two output plus the power supply fan, 512 ddr ram, etc....At first, I was getting alarms from the motherboard whenever the load on the comp was high, which i traced back to a high cpu temperature. I corrected this with a new set of bios that dropped the temp down to roughly 45 when idle, 55-60 when full load, which I've heard is ok for a prescott.

However, I'm still getting the beeping now at random times, the comp will sit idle for a couple hours and randomly give an alarm, a sort of eery siren noise. Any ideas what this could be from? It isn't temp warnings, i've changed those in the bios so they aren't going off....I'm thinking its a low voltage warning, considering I've got a prescott 3.2, 5 fans, a radeon 9600XT graphics card, etc running on 350W....would this be reason for this alarm, and would a simple switch in power supply correct this?

Thanks for any help....sorry for the lengthy post.

Have you installed the abit Hardware Doctor? It will show you voltages, temps, and fan rpms, which could cause alarms. On my IS7, the alarm was due to a failing northbridge fan, but the easiest way to tell is looking at the hardware doc, it will (or should) flash where the problem is.

I do have the ABIT eq installed, which shows me all of that stuff (voltages, rpms, temps), and I have gotten a few warnings due to a really low CPU rpm (which i'm assuming is cpu fan speed), which drops to roughly 1000 rpms and then the alarm goes off.....i was assuming this was due to a lack of power from the 350 watt supply, as some of the voltages seem really, really low, such as the -12v, which is usually around 7.5. I don't know much about recommended voltages, but i'm assuming every voltage should not be lower than what is recommended, in some cases much lower, which is what EQ is telling me is happening.

So, I guess my question is this - could the power supply be not enough for my system and be causing not only low voltage alarms, but also be causing some fans, such as the CPU fan, to be running low rpms due to a lack of power?

Thanks again for your help.

With big voltage problems like that, I would definitely suspect the psu. You're right on the borderline with your 350w, and if its an off brand psu, its probably not putting out even its rated power. Get a decent 400+w psu and see how far that takes you. I like the ThermalTake Silent PurePower psus, Antec and PC power&cooling are other good names.

Alright....so i switched my stock psu to an antec 430 pure power unit, and the voltage readings did not change in the slightest.....so am i to assume that meant the stock PSU was fine, or should I stick with the antec? Can anyone give me a "normal" voltage list of the major voltages, because I'm wondering if mine are off or I just don't know anything about voltages (i'm guessing the second option here)

Hi,
I had the exact same problem with my abit is7. I don't know why, but I know what happens, when the board beeps like that. Take a look at the PC health in the bios. Everytime you hear the beep, the temperature of the pwr drops to -127 or so.
There's a possibility to stop the board from beeping (the temperature will still drop) and I don't mean to just disconnect your pc speaker. downgrade your bios to version 19. Here's the link: IS7 Bios. (Why did they list it with LGA775 boards?)
This worked for me.
But now the idle temp of my cpu is 62. that's a bit high... v20 of the bios corrects this, so I'm thinking of disconnecting my speaker... or maybe return it and by another one?
