hi,

me and my dad made a pc and i trashed the PSU, CPU, and the mainboard
they have been replaced and something on the mainboard lights up but when we try to switch it on we get nothing.
the following are new:
the PSU
the CPU
the mainboard
the graphicsboard
the memory

i think its to do with the case itself but i'm very new to all this
please help!!

THere's a good chance there's a switch on your mobo that needs to be changed, or you've got your wires crossed on your main power switch. It happened to me on my very first build, everthing ready to go and nothing. I had to change a jumper switch on my mobo. What kind of mobo do you have?

Hello there

There are alot of reasons in this case. IF the mainboard was changed then you first must check the PSU connection to it and also the front switch buttons connections to the mainboard (power on mainly). Second make sure the PSU switch is on '1' position and try again. If nothing happends then disconnect the PSU from the motherboard and plug it in to check if it's good. If it's cooler starts up then your PSU it's ok so we've got a damaged motherboard. In my opinion i think the front panel connectors are not correctly connected to your motherboard.

Let me know if you solved the issue or keep in touch for more help !

Hi there. I have exactly the same problem! :-(
Os the "Power SW" cable which has to be connected to the MB and powers the whole thing?
