Hi, I've searched the Forum for any other similar posts but could not find any. I hope someone can offer me some advice please.
I've have been using a HP Pavilion A6652 Desktop for only a month. I have used the computer for half an hour this morning and suddenly I heard a noise coming from the CPU. It was a burning noise that got louder very quickly. A small light was flashing near the Power button, where the noise was also coming from. Before I had a chance to do anything, the computer made a loud POP noise and it cut out of power completely. I switched everything off at the mains. An hour later, I switched the computer back on it is working normally as if nothing has happened. According to the HP Troubleshooting booklet, the computer can switch itself off if it is overheating. I am surprised that this is the case for me, because I only had it switched on for half an hour. The CPU is not enclosed in any way to cause overheating and from my observations, the fans seem to be working fine right now.
Does anyone know any other possible explanations for this? I am concerned that this may happen again, or whether it will catch on fire somehow.

The most likely explanation is a fault within the power supply. Generally arcing sounds like that are only generated by high voltages, and in a modern PC these are only present in the PSU.
It is unusual though for the problem to be temporary - usually if they go pop they have gone for good, but yours may have an over-current cutout that can reset itself.
It's highly likely that it will do it again, but the chances of fire are relatively low because the PSU is enclosed in its own metal case, and the components ~should~ be made from self-extinguishing plastics. However - to state the obvious - don't leave it switched on unattended, and save any work you're doing regularly.0 -
If it's only a month old, I'd be taking it back and demanding it be looked at, and probably a replacement pwr supply. If it's going to start arcing, it's not safe.....sounds like you were lucky this time, however it deffo needs attention.........Gettin' There, Wherever There is......
I have a dodgy "i" key, so ignore spelling errors due to "i" issues, ...I blame Apple
