Stuck at motherboard screen unless I remove GPU

Been a Linus watcher since the NCIX days but no general interest in computer hw in the past several years, hence first time poster, only know about the forum as I listen to the WAN show every week.

For quite a while I've had problems when i turn on my computer, it would get to the Gigabyte splash screen and then sit there for a couple of minutes before booting into Windows, at which point everything is fine.

Yesterday though this changed and it would sit on the splashscreen indefinitely and would never boot, I am unable to get into the BIOS or the boot menu etc, the F2/Del keys etc just do nothing.

During my troubleshooting I removed the graphics card (GTX 970 - 4/5 years old) and then I got past the splashscreen immediately, though I ended up hitting Windows repair screens - long story short I had to reinstall Windows as I was in a loop of 'repair screens'.

 

I replaced + cleared the CMOS battery yesterday and tried a different PCI slot but I still have to wait a few minutes before it gets past the splashscreen, but then it booted up again like 'normal'. 

 

I have 4 sticks of RAM, though if removing the GPU seems to fix the problem, I decided to not try and remove sticks with the GPU plugged in to see if i get further. 

I potentially have access to another computer next weekend that I could try and plug the card into, probably need to power it from my PSU but i don't think this matters. If it works on a different motherboard, then potentially not an issue with the card? 

I'm happy that things are working "as normal" (like they have been for the past couple of years, waiting on splashscreen), but worried that it might stop working all together again like i experienced yesterday. 

 

Appreciate any help anyone can give thanks for your time

if other slot, or removing cmos battery did not help this is likely motherboard problem. 

you can try with other gpu but that is not likely the problem. 

 

 

full specs please?
