Hello i have installed a new GPU on my motherboard , GPU is working 100% on other PCs.
When Gpu plugged , fans spins but no signal via DVI/HDMI .
I switched from UEFI to Legacy bios while testing without results.
A lot of Bios options are greyed out .
therefore the only thing i can suspect now is the IRQ configuration of my bios.

Specs : (acer veriton m6610g)
gtx 750ti (plugged but using integrated graphics )
i5 2400 3.1ghz
7 gb ram ddr3
3 HDD ( 2x Seagate barracuda 7200 + Western digital )
corsair VS 450w

IRQ conflicts are a thing from the past, and is a non existing issue on modern systems.
I suspect that either your Acer is using a proprietary motherboard that cannot work with that GPU or your PSU cannot deliver the needed juice. The VS series is not really a good PSU.
What you can try first is to make sure BIOS is updated to latest version. Also make sure the extra power connector is connected to the GPU if it has any.

I think was running that GTX 750ti on a crap 300w acer psu , and the recommended watts for my gpu are 400w.
I have read something similar about acer proprietary motherboards on a slightly similar topic about Gpus.
i think im officialy out of ideas i'll try to get a cheap mother board with 1155 socket if you have some suggestions i would be thankful.
