Thought PSU was dead, go back to the shop and they test it, it works perfectly with all voltages correct, bring it home, plug it in , nothing. Again. I'm starting to get REALLY ****ed off at spending 50 + at a time for temporal fixes. Someone please help me. I feel like crying. :(
 
I can't just keep buying new parts! Whats the point when the PSU works, and how am I meant too lug a 7KG PC aroung the tube??
 
what did they test just the psu or the psu and your make/model of mb? left mb battery out for 30mins+ ?
 
they just tested the power supply cos that's all i brought from them, the thing is, my old power supply turns on with the pc but there's no signal to monitor and last time this happened i brought a new power supply and it fixed it. So i go to buy this new power supply in hopes of fixing my problem, No power to psu, so I take it back and they test the voltages and the psu on a motherboard and it works fine. So why wont the psu receive power here but the old psu does?
 
If they just kick started the PSU and put a multimeter as its only load then that's not properly tested.

If they tested in another machine with similar specs then maybe it's something more to do with your rig not passing power good test, there may be a short or something.
 
So the new PSU won't turn on the PC at al but your old one does, but the PC isn't working properly. It's possible that whatever is wrong with the PC is detected by the new PSU and it shuts down for safety reasons, while the old doesn't.

Well basically they tested with a multimeter first and I said show me it work in a rig so he got one of the MoBo bundles behind him and plugged it in. Voila, it worked. Bring it home and it doesn't even spin once, tried 3 different wall sockets aswell.

But even when i plug the PSU in separately the fan should spin right?
 
I can't see it being the psu tbh, the fact that it worked when you took it into the shop pretty much rules it out.

I suspect the issue is either the mobo or a stick of memory has failed.

I suggest you first off reset the cmos see if that fixes it, if that fails disconnect the hdd, all bar one stick of memory and all case fans (not the cpu fan) and try again, if it still fails swap the stick of memory in the pc for one you took out and try again. If you still have issues completely disassemble the pc and reassemble on a sheet of cardboard (check tho mobo for obvious signs of damage), this will rule out any if there are any short circuits.

Try the above and post back the results
