My computer is turning on.. But the u.s.b ports don't work, Ethernet doesn't work and my displays aren't working either.

I just bought a new mother board and installed it today.. I got it to turn on today all fans working and lights on but nothing else is working. The one before that just died randomly.. No clue whats going on.

What mobo (as well as CPU, DRAM, GPU, etc). Best to set up using on board graphiics if it has them, then change primary graphics in BIOS to PEG/PCI-E if using a discrete GPU, also need to load mobo drivers for things like USB, LAN, etc

Yash2000 · Nov 4, 2015

Mobo- msi z97 gaming 5
Cpu- i7 4790k
Gpu- asus strix gtx 970
Ram- kingston hyperx fury
Psu- seasonic m12 evo edition 750w

Im not able to access bios because theres nothimg displaying on minotor
When i connect the 4-pin cpu power connecter to psu it sparks and the motherboard shuts down

Tradesman1 · Nov 4, 2015

If sparks then bad mobo or PSU, do you have a different PSU you can try

Yash2000 · Nov 4, 2015

I dont have

Yash2000 · Nov 4, 2015

But is only sparks when i connect the cpu power connector. When i connect my gpu with the same wire it dosent spark

Yash2000 · Nov 4, 2015

Sorry the wire does not fit in gpu so im not sure is the psu is bad or motherboard but i have tested all 4-pin coonnecter in psu with my gpu and all of them works. The end that connect in psu of cpu connector sparks

Those are totally different power connectors, the GPU is fine because you are probably using a PCI-E connector from the PSU, the mobo takes a completely different connector, generally it's a 4+4. Plugging the PCI-E connector into the mobo is likely to fry and ruin the mobo - that's prob the problem

Yash2000 · Nov 4, 2015

My mobo has 4 pin cpu connector. So which is the problem mobo or psu?

Yash2000 :

Depends, may be either one, if you are seeing sparks, likely the motherboard is dead now even if you change the power supply. Only way to test is to try another power supply, but since you had some major electrical issues while installing it you may need to swap both power supply and motherboard now. And make sure you have everything hooked up properly. Did you read the manual and made sure the motherboard is in the case properly with the stand-offs all in place and power connections in the right places?

Yash2000 · Nov 4, 2015

Yes it was working fine for a week

Yash2000 · Nov 4, 2015

Is it possible that the procceser is causing the problem?

Yash2000 · Nov 4, 2015

My pc fell from a height of 1 inch by the front face side. And it droped on its foot. Not by side, so does this help?

Yash2000 · Nov 4, 2015

I forget to mention that front panel power led and restart button is not working and the back panel port is not working too.

hang-the-9 · Nov 4, 2015

Let's start at the beginning here, did you replace the motherboard because the system stopped working after the drop or did the drop not do anything and everything was working fine? If the front and rear ports are not working that could mean you don't know how to wire up the case and other things are also not in properly or that the motherboard is bad or the case connections are damaged. Did you install the case stand-offs for the motherboard when you replaced it?

Need details about what happened in what order.

Sparking motherboards are never good and really mean there is either a short somewhere due to a poor connection or bad grounding, power supply is bad or motherboard is bad.

Yash2000 · Nov 4, 2015

When the pc droped it stoped working before the drop it was running execelent, no i didn't replace the mobo. All ports werer workimg fine before thw drop. And the end that is connected to the psu of the cpu connector is spakring very fadly u might even not see it the end that is connected to mobo is not sparking. I have checked all the 4-pin ports of my psy by my gpu 4-pin and all are working but when i connect the cpu power conector in any 4-pin port it spark a bit and shutdown

Yash2000 · Nov 6, 2015

I just saw that theres a bended pin in my cpu socket in motherboard does it effect?

hang-the-9 · Nov 9, 2015

Yash2000 :

Of course, if there is a bad contact it will cause issues.

Yash2000 · Nov 9, 2015

I have RMAed my motherboard

Tradesman1 · Nov 9, 2015

Let us know how the replacement does
