No display, no beeps, fans are working

  JustHACE 16:11 27 Jul 2019

So yesterday my computer was hit and it froze immediately. I have turned it off and tried to turn it on again. Leds were flashing, fans were spinning, but there was no display and 0 beeps.

I have reseated everything few times, nothing changed. I have checked monitor and cables, they are fine. I have tested multiple RAMs, once a lot (30 at least) of short beeps appeared, so I guess that was because of a faulty RAM. I have checked PSU voltages and it shows 5.30V instead of 4.75-5.25, so that may be the case. CPU doesn't have physical damages, mobo is slightly bent, because of a heatsink I guess, but that may be a problem aswell.

Motherboard is Gigabyte GA-970A-D3 and PSU is Tacens Radix V650

I'm assuming you can get into BIOS? or did you get voltages using a multimeter?

Where was it hit?

anything under motherboard shorting to the case?

  JustHACE 17:14 27 Jul 2019

Well, I can't get to the BIOS, but maybe I am doing aomethong wrong. There is no POST sound, no display, no LEDs on mouse or keyboard indicating that PC my turned on. Just LEDs on case and GPU.

Yes, I have used multimeter. It was hit in the front side. I don't think that anything is shorting, but I will try breadboarding tomorrow.

Do you normally get a POST sound? are case fans running? have you removed refitted the cpu?

Try booting without any drives fitted, see if it beeps then or goes to an error message.

I borrowed mobo speaker from my friend after the accident, so I don't really know if there was a POST sound before.

Case fans are running and I have reseated CPU. I tried to boot it without drives and nothing changes. Zero beeps or messages.

Also I have tried breadbording. Still no display, no beeps.

I have just saw that sometimes CPU fan and one of GPU's fans aren't spinning. It's like they work at random.

Also I forgot about one thing. I have had some issues with RAM earlier. I had 3 sticks and all of them were working, but after inserting 3 or 2 of them, my PC had some problems (no display or some RAM wasn't available)

disconnect all power leads to PC press and hold the power button for 30seconds, reconnct power lead and retry, what happens?

  JustHACE 09:46 28 Jul 2019

Still no display, no beeps, some fans are spinning, one of GPU fans is spinning just for a second.

What happens if yo try to boot with the GPU removed? I assume there is no dedicated on board graphics you can connect to?

  JustHACE 10:19 28 Jul 2019

Yeah, there is no on board graphics. When I try to boot without GPU there are no beeps, case fans are spinning, CPU fan isn't. Also LEDs on keyboard and mouse doesn't work.

SOunding like either a power supply problem to the board (easy way isto try a substitute PSU)

or a motherboard failure if CPU fan is not turning.
