So I bought a GIGABYTE graphics card on Amazon, it had great ratings everywhere. I took out the old card, put in the new one, and the computer won't even reach BIOS. The fans all spin, but nothing loads at all, as a simple push of the power button turns it all off.
Tried in a 300w and 500w setup, same results. Tried in an older PCI 1.0 system, the computer boots and shows GRUB, but at the OS the card shows about 16 pixel rows along the top and nothing else.
The motherboard on the intended system is a PCI 2.0, the card is 2.1. The problem is almost certainly not plugging something in wrong.
Got a replacement from Amazon, same no-boot as the first card. GIGABYTE tech support is less than worthless.
Any advice or knowledge would be greatly appreciated.
