Unable to boot after replacing the graphics card

3 posts in this topic

Hi Guys,
 

Any advice on this please? I've swapped out the graphics cards from my girlfriend's PC and when powering on, the fans all come on (including gfx card), lights all come on the motherboard for about 3 seconds, then suddenly powers off, then after 3 seconds the lights flick on and instantly off. It then stays off.
 

ASUS SABERTOOTH X58 motherboard ATX LGA1366
i7 950 Intel CPU
1000W PSU
EVGA GTX 770
 

Previous card was a GTX 480. When I plug the GTX 480 back in, it boots up. The GTX 770 works in my PC just fine still.
 

I'm guessing a power issue? The GTX 480 uses 8+6 pin connector and the GTX 770 uses 8+8 pins. I've used different cables too. Tried removing all but 1 memory stick, all additional drives, checked connections all over. As mentioned it works fine with the old card back in and the other card works fine in my PC.
 

I just can't get it to boot at all. I work in IT and built these PC's, so I'm wondering what else could have been missed.

Hm that's strange,

Have you tried clearing the CMOS?

Did you try using compressed air in PCIE slot?

Did you check if there's a new BIOS for this card and motherboard?

I think this might be related to X58 only supporting PCIE 2.0.

Disable UEFI in the BIOS (return it to legacy) and it should boot. All 700-series and above are UEFI enabled.
