Hi, I've just installed a new Asus gtx 780ti and a new corsair cx750 power supply to replace my 560gtx, now the computer freezes at the first screen where it asks you to press del to enter BIOS. When I put the 560 back in everything works fine.

I'm running windows 8.1 pro 64bit and the rest of my set up is:

AMD FX-8350 eight core
8Gb RAM
Asus M5A97 with latest BIOS update (Had to install it a couple of months back when I installed a new SSD and have checked, there have been no new updates since 2012)

I'm not the most computer literate person but I know a bit and can usually get the job done if it's explained to me as if I'm thick haha. Any help would be massively appreciated

Thanks, Kris

Make sure the power plugs are all in for the video card.

It may be an issue with the power supply aslo, the CX series is not the best power supply and most people do not recommend them. They are cheaper than most other "gaming" grade PSUs which is why so many people seem to buy them.

The system locks up at the BIOS screen, it's not a driver issue at all. Either your motherboard has issues with he video card (possible but rare) or the card is bad or the power supply is bad. If you can test the card in another system that can run it, will help rule things out.

Uninstalled all my graphics drivers, still the same, I'll try and install the drivers for the new card before I put it in. Reason I hadn't done anything with the drivers is I was told I shouldn't need to and the geforce experience would sort it, I realise I probably should have tried before coming to beg the web for help though lol. I'll go and see what happens.

Hi, thanks for the replies, power seems to be fine, tried it with all nvidia drivers gone and new ones in and got no change. Ended up taking the card round a friends and it didn't even post at all in his machine, his board is an asus but older though. I've just decided I'm going to get in touch with the supplier tomorrow and get it replaced. Then if I still have an issue it looks like I'll be looking into a new motherboard... There's a cost I need days after buying a 780ti lol, joy :/

Thanks for the help though, it's appreciated. If anyone else has an idea in the meantime though I'd still like to hear :)
