help with computer, not starting

[lakeyb85]

hi guys

Anyone with any pc building knowledge, have purchased a pc. all new parts. pre built and when I got there I saw it working.

got it home and it wont boot. Not even a light from the motherboard or GPU when power unit is plugged in.

I have tried different plugs just in case and still nothing.
there is a quiet noise coming from the PSU and then when I push the on button it changes tone but the fans on the PSU don't even start or the red/blue lights connected to it. the box was very secure in the passenger seat with seat belt on when I drove.

any ideas what it might be? PSU dead or MOBO? no static or anything got to it either.

Thanks in advance

The only way to be sure is to test with different parts but the first one I'd suspect here is the PSU

yeah that's what I put it down to. I have tried everything, I have a spare pc upstairs but not sure if the psu is powerful enough for this pc. shall I try it with that one?

Well just for a quick power on test (not starting a game or anything) a working PSU should be alright even if not a high end gaming unit (what are the specs of the new machine anyway?)

I5 3.0GHZ
16gb DDR4
gtx 960
SSd 1tb
HDD 3TB

standar cd rom

what would be easier, just unplug the 24pin and plug new one in or unplug it all and just plug mobo in?

 

[SchizTech]

Well all you'll need are the 24 pin and the 4 (or 8) pin CPU power. The rest you can leave alone for now

tried new psu, only had a 4 pin not 8 but still no luck

Well next step I'd suggest is begin to strip down the system. Take out parts one at a time, starting with vid card. Even attempt to start without memory.

I tried with no memory still nothing. I had a ligh on for a moment in the Ethernet port but that went out. Does that mean anything?

Not particularly.
