Broken PSU? motherboard gone?

[Jonathan Cave]

Hi all,

My son knocked my HTPC of it's stand whilst it was turned on.

Whenever i plug a power cable in, the fuse in the plug blows and the PC obviously doesn't power up at all. i.e. the fuse blows as soon as i plug it into the PSU, i dont get the chance to press the 'power on' button i see the electricity jump as soon as i plug the power cable into the PSU.

Does this mean the PSU and/or motherboard is broken ? i'm not clued up in electronics... any help to get this working again would be great. All cables are snug, ram is fitted correctly and the CPU / fan is still on tight.

My bet is on PSU, but you have to take it to someone to check the PSU with tools. IF it did get loose and MBO got full PSU input then you can say goodbye to almost all parts in that PC. Still we can't help without touching those parts with
