Hi sifu, may need some help here. I have a desktop for about a year and seldom off it,maybe once a week. The thing is, when I got back from work, my desktop is shut down and I can't turn it back. No light, no fan spinning. How would I know this is power supply failure or mother board failure? Many thanks in advance.

well, if its me, ill try to replace with power supply nearby (borrow from a friend etc.) to test whether psu is the culprit.
since at least, if mobo failure i guess the fan would spin even a little.
I guess so but just need some advice here as well..I don't have anyone here near me with a desktop to borrow a psu..guess I have to find a computer shop.and bring my computer to them..haishh..as long as it's not motherboard failure then it's okay..
