sudden power off

I have a Mesh tower pc which is just 3 years and 1month old - 1 month out of warranty.

Whilst I was working on it - it suddenly powered down without any warning. I have done all of the obvious things like checking that the leads are in and hoovering out the inside of the chassis - it was very dusty.

When I try to power up again - the power up sequence goes on for between 5 and 20 seconds before powering back off again. During this time, all of the fans are working.

Help please

Have you added any new hardware? It could be the psu (Power suply Unit) is failing.

I had a phaze of this happening when I added a new dvd drive. I just bought a higher wattage psu. Seems to be working fine now.

either faulty PSU or overheating - fans may be running but are the blades clean ? are the heatsinks on the cpu clean of dust?

Do you hear any beeps at all while it's trying to boot? If yes, do they resemble any of these click here?
