Black screen on boot.

[CrystalBalls]

Hi all

I’ve built a new pc this week and while I’m waiting for my new graphics card coming so I’m using my faithful 980 ti.
With the pc spec being a lot higher than my old one I thought I’d overclock the card until my new one arrives. Ive done it to this card before successfully so didn’t hesitate.
I used MSI Afterburner for the oc. I upped the power limit to the max and applied a 100 MHz overclock and the pc ran sweet though the Unigine Heaven benchmark. I then upped it to 150 and again alls well. When I upped it to 200 MHz heaven crashed and the pc froze also . I shut down with the power button and then rebooted. All I get is a black screen. Can’t get into bios, don’t see anything on screen. Just black all the time. Doesn’t show windows login screen or the mb logo.Nothing.
The VGA status light on the motherboard is on constantly as it tries to boot.

I’ve tried the 980 ti in my old system and it works fine.
I’ve taken the cmos battery out for 24 hours to no avail.
Tried 1 bank of memory and swapped them over. No change
Tried GPUs in the other pci slot which makes no difference either.
Disconnected all hard drives too.

Gigabyte X470 gaming 7 WiFi
Ryzen 2700x stock

EVGA 750 Watt Supernova G2

You could try remove the CMOS battery again, and you also need to remove the 24 pin and press on the power button a few times to drain the caps. Like was suggested to me to try and fix my past problem.

Also maybe try changing the bios switch on the motherboard to change to the backup bios and see if that changes anything for you, good luck.

Do I have the power supply on or off when I disconnect the 24 pin connector?
Ive already changed to the backup bios but it didn’t work.
Thanks for the reply by the way ����

Power of > remove 24 pin > press power button

If the above doesn't work for some reason try unplugging you monitor from the plug socket and leave it for 5 minutes then plug it in and see if it boots. I had to do this with my 1080 once

I’ve ended up sending the motherboard back and I’ve ordered Asus ROG HERO board. Reading reviews on websites it appeared to me that this issue happens a fair few times with the gigabyte board. Better to be safe than sorry..
thank for your input guys..
