No signal after install Gigabyte GeForce GTX 660 OC 2GB GDDR5

[mrpolley2012]

I cannot seem to get my computer to work after installing a new Gigabyte GeForce GTX 660 OC 2GB GDDR5 and also a OCZ-ZT 750w psu. I can't even access the bios as the mobo won't post, the monitor shows no signal but all the fans including the graphics cards and hdd comes on.

Here is my system as it is now:

Intel i7 3770
GA-H61M-DS2 DVI r. 3.0
Gigabyte GeForce GTX 660 OC 2GB GDDR5
16GB RAM


I have gone back and reinstalled my old graphics card and the whole system works fine. I can't see any reason why the system wont work with the new graphics card. I tried turning off the internal vga and setting the priority to the pcie in the bios prior to installing the new gfx card....

Any ideas? I spent a lot of money on this new card and am very anxious :S.


Many many thanks for any answers.

Make sure you sit it properly. Have you checked the external power needed for the GPU (PciE )

I have just sat the new card in and it is all completely in and also I have plugged in the pcie power cord from the psu. In fact I have changed the pcie power cord just in case it was that (the psu is modular).

What is the other card that is working on your pc.?? Maybe the card is faulty. Try it on another PC if possible ? Ask a friend to borrow his pc .

the other card is an MSI GeForce 630gt 4GB. I do not have access to another PC as all my friends have laptops .

Well i wouldnt send it back w/o testing it. Try to find a local shop maybe ? And turn on the pc w/o the GPU and check the voltage in bios.

 

[mrpolley2012]

check the voltage? of what? do i need to increase it if it is too low? what should I increase it to?

 

[prototype18]

The 12V voltage. Maybe Psu dsnt deliver good 12v. But im more on the dead GPU side

 

[mrpolley2012]

turns out my motherbord doesnt like new graphics cards ^^. Compatibility issue i guess although the mobo manual states it should work. Well anyway I ran to the shops and bought a more up to date mobo for £55. Transferred the cpu and installed the new gfx card.

IT WORKS!!!
Thankyou so much for your help anyway.

I still have the same problem. I am stuck with my 8800GTX since my MSI 650GTX TI Boost or GV-N66TOC-2GD (Gigabyte 660GTX) is not working. Please don't tell me it's my mobo, I mean the other GPU's are working.
