i just build a gaming rig, i connected everything possible and when i when to turn it on the cpu fan spins a little and the power light on the front of the case lights up then every thing just cut's out.

my specs are;

i5 3570k
gigabyte GA-Z77-D3H
Radeon 7870 tl
corsair 600w psu
corsair vengeance 8 gb
1tb hard drive
coolermaster hyper 212


whilst applying thermal paste to cpu, a little amount of the paste dripped on to the side of the cpu. but no thermal paste got on to the pins or the motherboard. apart from that the rest of the build seemed smooth.

could i have some help please, thanks.

if its a new build just double check that the power connectors for the motherboard are all in properly. the next step would be to take all the components out breadboard it with the bare minimum, just cpu, 1 stick ram,hdd, and use on board video. if it starts and stays started, add the parts one by one.

if it doesn't start though, its not a good sign, ive had a similar problem before, twice, and unfortunately for me both times it was my motherboard... i hope this is not the case for you, alternatively it might be the PSU. you can do a simple "paperclip" test to see if it runs, but is in no way a definitive test.

i really hope it is nothing serious, i know how frustrated you must be right now.

good luck, and let us know how you go.

oh, and i wouldn't stress about the thermal paste, i've had some spill over the sides,as long as it doesn't get on the bottom you should be good.
