hi. I've been trying to install my new graphics card for a awhile now but i keep getting stuck at the blue hp logo screen when i install it and try to boot up. I dont know what i am doing wrong, for i thought i had installed it correctly. If anyone can give a good step by step process (not oo much detail is needed) that explains everythingnecessary to get this thing working, i would be most appreciateive. The last graphics card i installled was an amd 7770. I have a 650w PSU, and a gigabyte 2ac8 mobo, but this is the first time any trouble has arisen. I dont think the card is dead either, i can hear its fan going when i start it up, but the computer just wont get paast thte hp logo screen.

also, for my motherboard, where would i go to update my bios as I dont believe they are up to date and this may also be the cause of an error? its a gigabyte 2ac8 model

You haven't posted your specs, and any answer will be detailed, there is no 'quick dirty answer'. Put back in the 7770 card and download / run SPECCY and give us your specs on your computer. Then go to HP for you model PC, and see about a BIOS update OR if your PC even can support the 760.

The HP LOGO screen is your BIOS screen, as that displays on the 760 fine, your hardware is booting okay, but it seems not to 'know' what to do after that (enabling 3D video, handing off to Windows BootLoader, etc.). I would normally suggest the PSU is the problem (enough power for low end b&w text but not enough power to energize for 'graphics') but the PSU seems to be enough, you might want to swap the power with another +500W and make sure that 650W isnt' failing. Otherwise the last thing be the GPU itself got 'shorted' and can't switch from low end display to higher end 'graphics', and need to be RMA'd.

Okay, sorry, slipped my mind. Off the top of my head here is the relevant information. Tell me if you need anything else.

psu: fx-6100
gpu: 7770 (gtx 760)
ram: 10gb
mobo: Gigabyte 2AC8
PSU: 650W
computer model: h8-1214
OS: w8.1

Went to HP page and found my computer, there wasn't an option for a bios update, but a different program i downloaded (BiosAgentPlus) from esupport.com said that my bios were in fact out of date. Bios currently on my pc: AMI ANG_716 4/5/2012, so I assume version 7.16 last updated april fifth 2012. And I dont think my PSU is failing because it runs this card fine (the 7770). If it means anything, I tried running the computer for a few seconds without the case cover to see if the fans on the gpu were turning, so I dont know if that means its not dead or what. Thanks for any help, I am at a loss

I was saying on the PSU, if it was failing it may be pushing 450w or 500w (especially if it was a cheap made one they are notoriously underpowering) where the 7770 uses less power (http://www.legitreviews.com/gigabyte-radeon-hd-7770-oc-video-card-review_1873/10) then the 670 (http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-670/specifications) uses, swapping back to the 7770 wouldn't prove anything. Your best way to resolve this is test the 670 in another PC with a 500W+ (friend, family) and see if it work or not. If it works, then the PSU is probably the fault here, otherwise the card is at fault (fried).

Ok, so you are sure it isnt the fact the bios need updating? It is a card or PSU malfunction? I have no where to test either the psu or the gpu other than my own computer, so I am a little stumped for ideas. If there was a place i could try updating bios to rule that out for sure, do you know where? cause I havent seen anywhere to actually update them. I got the PSU just from best buy, it was around 50 bucks, I dont know if that is high or low quality, but I cant remember the brand name. (I know now never to go to any retail store for anything electronical though). And I have read online other people being fine with 650W or even 600W psus, so I really dont think that is it, but what do I know. If it is fried, do the fans being on not indicate anything? And if it is fried, which if it is it probably was when it was in the packaging, do you think I have good chances of returning it? Thanks for the help so far btw

If HP says no update, then I wouldn't trust a third party site that probably will 'charge you' before you can actually get the BIOS update which may in fact just infect your PC at the lowest level.

First if they repacked it yes it could be fried before you got it, but more then likely a simple mistake on your part (not properly grounded before handling or inserting) EASILY fries electronic parts.
Second, I am not saying 600W or 650W wouldn't be 'enough' to power the card, I am saying THAT specific PSU in your PC may NOT even be pushing out that much (yeah 50 is too cheap) and maybe IN actuality pushing 450W, but without a real set of electronic engineering device (Ohm meter, etc.) to test all that the only option you have is to get a name brand PSU around 600W and test it in your case (since you have no other computer to test with). If that magically starts to work, great, if not then you know the GPU is hosed up most likely.

As noted by what you said, you can turn ON the PC with the 670, it does DISPLAY the HP Logo, but not past that. The HP LOGO is low end graphics, your background / icons on the 'desktop' is high level, if the 670 can't 'power up' to support that either not enough power exists or the chips are damaged. If you weren't' getting ANY display at all or another description of what happen I would suggest a different path, but we see 'power' is getting to it, not enough to push to 'the next step' though.

I am not doubting I could have mishandled it, but man that annoys me if that is the case. I grounded myself literally every time before and after i touched the thing. If it was fried, could its fans still work? Or would they be off too? what would you suggest I do if it is indeed dead?

Fried as in the small chips themselves are 'unprogrammed' and just sit there. Electricity powering the fan has nothing to do with the 'programming' of the chips themselves that process for rendering of graphics.

I already suggested, get a second PSU (new and of good quality) and 'test' the computer. If the same problem still persists then your down to just the GPU and you can only test the GPU by putting it into a 'working computer' and see what happens. Does it work in another computer but not yours? Does it work when a different PSU is tested? these are the questions needing answering.

Okay. Do you know if there are stores or places i can test the card where they can pop it in a computer? My friends that I game with on the computer live across the country and my friends that are close by arent into PC gaming, so I am kind off stuck there. What would you suggest I do about testing it? in the meantime i think I will get a differnt PSU. What brand/wattage would you suggest? I am not experienced in PSU brands as they are not as popular or mentioned as much. I will do my own research too, but what would you reccommend?

Only thing you can do is bring it to a mom and pop IT shop and see if they can test if it works or not, since you have absolutely no other resource available. But if your going to do that, then you should just take the whole thing in and let them service is, since you really don't know what is the cause of the problem at this point and the 'results' are inconclusive (one video card works fully, the other works to a point then stops).

This right now is the risk with self-builds, you are 'on your own' literally, and a good reason when in your position to instead just go with a pre-built, alot less hassle. Just a word to the wise going forward
