New graphics card in and old computer. Not working plz help!
I recently purchased a new video card (MSI Radeon HD5670 512MB) for my 5-year-old system. I made sure to research that the product I was buying would be compatible in my PC. The power supply should be sufficient, the card fits snug in the backwards compatible PCI-E x16 expansion slot, I was also very careful with installation itself.
After installing the card and powering on the computer, the card's fan spins but the monitor stays black (like in sleep mode).
Other than a dead card, what are some other things that could be causing this problem? I saw something while searching the web about a Gigabyte BIOS update for pci-e 2.1 cards, but its 'use at your own risk' and the update isn't posted on Gigabyte's website so I'm a bit hesitant on downloading it.
Any and all help is greatly appreciated!!!
