    Hi guys, heres my problem:

    My comp (basic specs below) will not post. The power light on the motherboard is on and when the power button is pressed all the fans spin up as normal, however instead of the usual short beep at post it gives one continuos tone.

    I have checked the beep codes at ASUS's site but there is no listing for one continuos beep that never stops.

    I've also tried removing each of the gfx cards to see if one of them is the problem, and each of the dimms with no change.

    I did notice that the heatsinks on the cpu and gpu coolers are pretty dusty so i think my first step will be to get a can of air and take the whole thing to bits for a good clean. I'm in the habit of keeping an eye on the cpu and gpu temps even while i'm gaming and i've never seen them go above 60 though.

    Does anyone know if the continuos tone could be because the dust is interfering with the rpm of the fans perhaps? Or does anyone have any other ideas as to what the beep might indicate?

    Any help much appreciated :)

    Is the beep from the video card by chance?

    What is the make and model of your power supply? Have you tried another power supply.

    Nah the beeps from the MB speaker. I've heard the noises those GTs make, definitely more of a whine than a beep XD

    It's a Thermaltake 700w Modular PSU, the only other PSU i have lying around is only 150w so i doubt it'd cut it as a tester, plus it doesn't have the PCI-e power lead. :(

    Have you cleared the CMOS via the jumper?

    Please check your ram modules and remove one of them at a time, then try to post.

    Done, still not posting with the same continuos beep. Got a new stick in the post just in case it is that though, should arrive in the next few days.

    I would suggest taking the system down to one video card for the testing, and try each one separately. Also I'd try to get you hands on another power supply to swap in as well.
