I recently received a new GIGABYTE Radeon HD 7950 graphics card for my birthday. I removed my old Radeon HD 6850 ICEQ X Turbo and connected the new card, through the PCI-E and GPU slot, I started up my computer to install the drivers and make sure everything was working dandy. But I didn't get that far. My monitor was unrepsonsive, and detected no signal from the computer. I could tell it was connecting with the cable though, as indicated by the light on my monitor that assured me it was "thinking", yet no signal came. I did some researching on my iPod and eventually reinstalled my 6850 to try some things.
As of now, I have two hypotheses. It's either:
A) My power source, which is only 430w where the 7950 needs 500w. The strange thing is that the 6850 ALSO needs 500w but it runs fine (as far as I can tell). I also read that usually when you try to run a card with a power source under the requirements, the computer just won't start up fully. My friend also had that happen to him. It could very well be that though, that I need a larger power source.
Or it's the BIOS in my computer. This one is a bit trickier. I thought it might be that my BIOS needed updating in order to recognize the new graphics card, in case it didn't have any clue what a Radeon HD 7950 was. However, after going on the HP website and finding my model (HPE-410f) there were no BIOS updates available. Now, the last version was 6.07 and was in 2011. So that seems a bit dated to me, that might just mean it's fine and dandy and doesn't need to be updated, but I am unsure of this. I tried to find information about the BIOS itself, which was by American Megatrends Inc. I don't know which lines are important so I'll include them all along with a picture of what I found on my motherboard: 686, AMBIOS®, ©1999, FE74, 9775. I don't even know if that's useful information. In relation, I was informed by the internet many times that my BIOS and motherboard need to match or compliment each other. I can't find any indication on my motherboard of what it is, model or manufacturer. According to HP and a program called PC Wizard, I have a FOXCONN 2AB1. However, my computer was refurbished in the Summer of 2011, not long after I received it as it was a floor model and the motherboard was fried. I don't know if they replaced it with the same motherboard (though I assume they did), but like I said I still can't find any recognition of a manufacturer on the actual motherboard. Anyways, after learning that there was no update for my BIOS I did more researching and stumbled on some forums mentioning "Flashing the BIOS" which looks to me like it updates your BIOS to work with that graphics card, specifically theses flashes were from the GIGABYTE website. On the website I was told to make sure that the flash BIOS version I picked should match that of my BIOS and motherboard, but I have no idea how to determine that. So, I'm rather stuck on the BIOS issue.
If you think that it could be anything else or have information in relation to my hypotheses, I appreciate any input and advice that could get this resolved.
