My old PSU burned out the other day, so I bought a new one. The new one arced when installed so I took it back and exchanged it.

Now I can start the machine, but at random times ut will shut off and start beeping high/low tones non stop. I think it may be a RAM issue or a RAM slot problem so I've been swapping each of the 3 sticks out and keeping track of what happens.

So far, only one stick causes the shutdown, but it's only happened twice and pretty hard to repeat.

Thinking it could be a temperature issue, I ran BIOS and my CPU hovers around 55C/131F. The system temp is 31C.

I have an MSI mobo (KT4V MS-6712) with 3 sticks of 333MHz 512MB RAM (PC2700 DDR)

Any ideas? Thanks.

eww, I'd guess your mobo got a good jolt, if you got the money replace your mobo or at least bring it to a shop to get checked-out.

Keep in mind that the bios temps are unloaded. You are probably into the 60's if you run any demanding stuff on your puter.

Download this home version of Everest. It's free. Then after install, start it up and go to computer/sensor section and check temps again. Play a game and come back to the temp section and check temps again.

BTW, It sounds to me like you might already have some third party temp minitoring software already installed on your puter. That high/low beep just caught my ear. Could be a high temp alarm because your temp thresholds aren't set high enough. Just a thought. I assume the alarm turns on after entering Windows. Is that correct?

One other thing. Blow all of the dust off of your heat sink and all fans. This should improve cooling a few degrees.

YO

The alarm starts after the comp shuts down. It happened one at windows load, right after password keying and once after about 30-45 minutes of me trying to load the system heavily by running all sorts of memory intensive things at once.
