RAM, Mobo or PSU at fault?

Brand new PC build, worked fine until half way through windows install then turned off. Now it only turns on from anywhere from 1 second to 1 minute (can get into BIOS) before turning off again.

Removed EVERYTHING apart from CPU, RAM, PSU and behaviour is the same. Tried every combination of ram. With no RAM in at all the power stays on but obviously nothing happens.

I've no other hardware to swap and troubleshoot with so not sure which bit to RMA.

Could be any one (or more) of a few things;

First thing I would check is for overheating. Start by checking the thermal paste is present on the CPU, and making sure that the CPU cooler is fitted properly.

Second option is that the motherboard isn't earthed properly. Check that the mounting points are all present and that the screws are nipped up.

Third, you should be able to check the RAM through Memtest (click here option is that one or more of the components has a fault - a cracked motherboard or faulty PSU are tricky to diagnose without 'spares' to fit and test.

oh dear, more mistakes in a post!!

Third: use click here will test the RAM

Fourth, a cracked motherboard or faulty PSU could be the cause. Not to easy to diagnose though.

Check that you have removed the protection from the heat paste on the heat sync.
