No display but running...

D3T0 · Sep 19, 2015

So my new build wont display anything. Fans wind up, but it doesnt out put anything nothing on my keyboard or screen. I thought i had too weak psu (550w) but it seems it might be something on the mobo since it cant lit my keyboards led indicators nor any other device... Ive tried disconnecting every part, one at a time, yet nothing happens.
(Components: i5 3470, 8gb 3ddr, gtx 760, corsair 550w 80+, asus mobo also aio liquid cooler)

There are two reasons which may include in your problem
(1) Display Wire Problem
(2) Ram Problem
Try to unplug RAM and clean its yellow area with Carbon Eraser Sometimes There is too much carbon on RAM which
is happening this. If not Check Your Cable

Your motherboard should have some type of debug output, either through a 2 digit LED, or PC Speaker beeps (you need to have a speaker installed in the pc speaker slot on the motherboard to hear the beeps of course).

This should let you know exactly what your issue is.

The Psu is plenty power

D3T0 · Sep 19, 2015

I cleaned the ram and checked the cables both vga and dvi. Also i do have a led on the motherboard but it indicates if there is power or not, no speaker installed.

Did you motherboard come with a beeper?

BrandonYoung · Sep 19, 2015

Thanks for the upvote because your phone went crazy

D3T0 · Sep 19, 2015

No, there wasnt any kind of beeper installed or in the box.

D3T0 · Sep 19, 2015

Brandon, im sorry but im on my phone and its kinda out of control

BrandonYoung · Sep 19, 2015

No worries man. One thing you could check is that your CPU is mounted well, and your AIO water cooler is tightened down good. You could also check to see if you have a display from the onboard video found on the motherboard, this may require you to uninstall the GPU temporarily. This would be a good time to check that the GPU is seated in the PCIe slot well (and locked with that tab or slide).

Other things you could check:
24pin atx motherboard power cable is seated firmly into the motherboard, these can be tight and difficult to get seated firmly.
Make sure your 4pin (or 4+4pin) CPU power cable is seated correctly/firmly.
You checked the ram, so that hopefully isn't the issue, but the tabs on either side of the ram should be locked into the ends of the ram stick/s.
As DiegoD stated, make sure your GPU has the appropriate 6/8 pin PCIe power connections connected.

Keep us posted.

Did you check to make sure the 8 or 6 pin connector was plugged into your graphics card? I know the majority of 760's have both a 8 and 6 pin but reading the manual will tell you which one to plug in.

D3T0 · Sep 19, 2015

All wires are connected. Ive teared the build apart 3 times during last 24 hours also ive tried onboard video and the cpu cooling block is inplace tightly.

DiegoD · Sep 19, 2015

It's a leap but have you tried resetting your BIOS? Unplug your PSU and run some metal object ie. screw driver, paper clip, screw, over the CMOS pins a couple times.

BrandonYoung · Sep 19, 2015

I would really try to get a speaker to hear the debug beeps. You could do this with any low power speaker or old headphones, just be careful with raw copper on your motherboard connections... In theory you may be able to do this with a LED as well, and just watch for the flashes instead of the beeps.

If you have some speaker cable, you could cut it flat so you cant see copper exposed, and just push the cable insulation around the speaker pins on the motherboard, this should hold them in place as well..

I did use the jumper but i dont know did it reset.

D3T0 · Sep 19, 2015

I just connected extra case fan and i noticed it spun slow as hell and no torque at all. Could it be that my fans (4case fans, radiator fans, gpu fans) has overloaded the psu?

BrandonYoung · Sep 19, 2015

Fans are pretty low amperage. Its doubtful they overloaded your PSU by themselves. Maybe its just a really slow fan, or your motherboard (the functional bits) initially spins fans pretty slowly.

Go for the speaker, it may be the only way to know if it is a PSU, CPU, GPU, Motherboard, or Ram issue at this point.

BrandonYoung · Sep 19, 2015

Just an afterthought, you are using the motherboard standoff screws that were provided with your case correct? If your motherboard is shorting on case mount, it wont work.
