BIOS freeze on boot when I install an EVGA GTX 760

[sthackrey]

Hello,

I just bought the EVGA GTX 760 4GB (previously ran a GTS 460) . I have tried to install it on my machine but it keeps freezing at the BIOS and doesnt boot up. I have updated my BIOS to the newest version but that hasnt solved the issue. My PC spec is as follows

Motherboard: ASUS M4A88T-V EVO/USB3
Processor: AMD Phenom II 3.2Ghz
Power supply: Coarsair GS800
RAM: 16Gb
HD: 2TB SATA.

Really appreciate any help you can provide as I am totally at a loss and dont know how to solve this.

Cheers,
Scott.

did u connect the Graphic card power supply "Two 6-pin" connectors properly?

GTX 760 requires 30Amps on the +12V Rail

yes, I connected the 6 and 8 pin power connectors. My power supply is 12v with up to 65A.

Cheers,
Scott.

I had a response back from ASUS saying that the motherboard wont support the card. They say that because its a PCI-e 3.0 (despite the cards being backwards compatible) that some of their motherboards will not support these cards even if they have pci-e 2 x16 slots. So I bought myself a new MOBO, its christmas! hahah.

but, i heard ....PCI-E 3.0 has backward compatibility with PCI-E 2.0

i see....it's not true in all case huh ....

yeh, apparently not for older mobos. New mobo comes tomorrow, hopefully. ASUS were not very helpful to be honest.

So my new motherboard came and I installed everything and I get the same problem. However, the card does work on the PCI-e x4 slot which is bizarre. It doesnt work on any of the other slots. I got the Sabertooth 990FX R.20 motherboard which I know others have running PCI-e 3 cards. I am totally vexed as to why the card works great on the pci-e x4 slot with amazing performance BF4, so I know the card is working fine. I have also flashed the mobo with the latest BIOS version. Any thoughts?

Cheers
