Building PC from scratch but doesn't power up!

MattyLion · 05-12-2009, 05:11 AM

Hi there, I've just built my first PC... everything seemed to be going well until power up!

The switch on the back of the PSU is on and the motherboard led lights up to show that it's getting power. When I try my power switch nothing happens, I even got a cheap motherboard testing kit with a little power switch in case the one on the case was loose/knackered, still nothing.

It didn't blow or bang or do anyting upon first power up. I'm pretty sure the PSU is connected to the 24pin and 4pin slots on the motherboard correctly.

There's literally nothing upon power up though, no fans, no hard drive spins, nothing.

Motherboard problem maybe? Power getting to it to turn on the LED but problems elsewhere?

Any help would be greatly appreciated as I'm slightly worried I've just thrown £500 down the toilet!

Thanks

what is the make and model if the power supply? Have you tried putting a screwdriver across the 2 pins where the case switch gets plugged into the motherboard?

Take everything put of the case and do a on-the-bench test.
Place Mobo on Non_Conductive surface-Install CPU and heatsink on the Mobo-Connect the PSU-install one stick of RAM-Installm Video Card and connect the Monitor-use a small screwdriver to jump the Power On pins.
