I'm still seeing a light on the psu and the postcode on the motherboard is on but the pc won't turn on, also the psu smells like it has burnt out.

what is "burnout", did you mean "Brownout", or did the PSU just Die and you could smell a burn order.

In either case, if you have a "burnt oder, time for a new PSU. The question is did the PSU die, or did a problem with the MB/GPU/HHD/DVD Drive cause the PSU to go into an Overcurrent condition and fail. This is hard for the average person to tell.

(1) If you (or a friend) have a spare PSU, then try it.
(2) If not then get a "good" PSU and start from there.

(3) Should provide your system info
At Min need:
- MB
- Current PSU, And in your case replacement PSU
Would be nice:
- Nr HDDs, DVD Drives, and memory info

Unfortuantely wasn't at home when it happened. I can smell a burning smell which seems to be coming from the PSU.

I'm waiting for a friend to call as I'm hoping I left the old (but unreliable) PSU at his. Will come back with systems specs once I've tried a replacement PSU if it doesn't fix the problem.

Thank you.

Burnt smell? Get a new Power Supply, and hope the old one didn't do any damage to the rest of your system when it suicided...
