Help plz, pc wont boot, totally black

[zerodddd]

Suddenly the problem comes.
I press the power button and the light and all fans (fans in front, rear panels and the cpu fan) are on, but then, nothing happens. After a while the monitor enters energy saving mode.
I cant even see the figure of the mobo or enter bios, nor enter windows os. It is just totally black.

I tried in such ways:
1. Switch hdmi cable from my r9 270x (and just uninstall it) to the integrated graphics card. Issue remains.
2. Normally I have 4*4gb ram. Right now I only use 1*4gb. Issue remains.

I wonder if this could be a mobo problem most probably.

And in such state, the restart button losts its function. The only thing I can do is press pw button and hold for several sec to power it off in force.

Mice and keyboard led dont light.

If I unplug all the ram and try to boot it, there is NO beep alert.

Mobo broken, eh?

bump, bump, bump

First thing first, the motherboard speaker is attached?

Second, remove everything except processor, plug in one stuff at the time and see if there's any response.

If all things failed, can bring to Nigel at Sim Lim.

Tried. Not really has any response. But today I took the mobo alone to CDL of Gigabyte and after check the staff told me there was nothing wrong will my mobo.

And after I came back and installed all things again and tried, the issue became the same as described in this thread http://forums.hardwarezone.com.sg/h...s-spin-up-brief-moment-then-quit-5514715.html
I noticed even the fans were on the spin speed was totally different from normal one (really slow). So I wonder the root of the issue is in the psu.

should not be monitor issue. That one can be connected to my other notebook and my smartphone (via MHL) and works well

I do not know which one is more convenient if I take the corsair psu to CONVERGENT or if I take all stuff to Nigel@SimLim

The psu is still in warranty. But I noticed that there was a thing called RMA? What is that? I cannot go to CONVERGENT directly?

If successfully deduce its psu then bringing to convergent is better of coz. If you really have no idea and confirmed every individual part is working as intending but not working then put together, go to Nigel.

Rma is basically claiming warranty for your defective product. Take it this way. Hope you understand what it is. Otherwise Google is your best friend.
