Try reseating the GPU

I had a similar issue a few weeks back and that fixed it

You've re-seated it, but have you made sure you're 6 and 8 pin power connectors are fully in? Sometimes they can push against each other and not be connected properly and that can lead to power issues. On my PSU it's actually 2x6 pin and 1x2 pin so that can be a tight fit.
