Model s3541.uk - on pressing the power button, beep sounds for 15 secs - nothing appears on screen. After 10 secs quiet, beep repeats. Everything secure/reseated. Can I assume it's the mobo. If so, how do I find a correct replacement. Thanks

Have you tried booting up in safe mode. or maybe make sure none of the keys on the keyboard are stuck down.

Hmm, I don't think one can assume anything in particular - but I would suspect faulty RAM.

  Nontek 09:42 14 Apr 2011

Further to my above comment - I would remove all RAM, then try each RAM stick in turn, if you have more than one stick could be just one of them causing the problem.

If it was a stuck down key, the sound would probably be continuous.

A replacement mobo would be a difficulty, I think hard to find, so much smaller than most - and consequently more expensive than a 'normal' size mobo.

Another thought - the problem could be Overheating - being a small case makes this a possibility, especially if the inside has not been de-gunked in a while. Clean out all dust etc, especially around any fans and vents.

Thanks. Did clean the dust out yesterday (wasn't too bad). Have tried without RAM - same result. Different keyboard to the one normally used. Can't access anything - beep starts immediately the power button is pressed. Have found a source for the mobo (if it proves to be that) fromlink text

Yes, mobo perhaps ...... but a second opinion from a local PC repair shop might be a good idea.

Most likely is a Ram problem, PC will not start without at least one stick in place. So try one strip at a time and make sure that its fully pushed in. Its a none standard beep code you are getting

Check this out, I cannot use the link as the page will not finish loading so you will need to copy paste the link to a blank page Address Bar

Thanks woodchip. That website pretty much ties in with my problem. Don't think it's PSU, as fans run etc. Tried spare (good)RAM. Same result. Different beeps with no RAM (same as the link).

  woodchip 11:26 14 Apr 2011

As to the last post in the Link I gave, you will not get nothing without CPU as that makes everything work. So you will not get no beeps. But you could try some heat paste under the CPU after cleaning the old off it
