A Beep

By accecareanima ·
A Beep with three second intervals is coming from a computer at work. It will eventually stop almost as if it sputters out. I can leave my computer on for a few days, with no problems. Then out of no where the beeping will start back up again. I am thinking a slow falure of some hardware, but I am not sure. Thoughts?

POST beep?

by Fixmeup In reply to A Beep

Is it a POST beep or is it while you are logged into the OS? This sounds silly but we had an issue with a 'sometimes-stuck' key on the keyboard that would beep at weird times and not others. Try swapping out the keyboard.

Beep source?

by jswentworth In reply to POST beep?

Are you SURE of the source of the beep? We frequently get requests involving beeping computers that are actually the UPS next to them, or some other nearby device.

Beep Source

by accecareanima In reply to Beep source?

I don't have a UPS attached to this computer. Thought I should get one for this.

Post Beep?

by accecareanima In reply to POST beep?

Its starts when POST begins, I actually made sure that wasn't the problem because I have had that happen before.

by Fixmeup In reply to Post Beep?

So when the beeps start, are there any on-screen messages?

Try reseating the video card, and RAM to rule out chip creep or dust.
You could also swap components from an identical computer so you can rule out if a stick of RAM is bad etc..

Good suggestions, ill try that and see if I can rule out that hardware.

Maybe RAID

Maybe my RAID controller?
