Just installed a new Powercolor Radeon HD 7850 for my system. Also bought http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...
to supply it.
My computer was originally this:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en...
Installing the new graphics card gives me a "No Signal" screen that I can't seem to get past.
I've removed and reinstalled, updated BIOS, deleted previous graphic drivers, tried booting in safe mode, tried installing drivers from provided cd before installing card.
The fans are spinning, it's detecting that I'm plugging in the HDMI cord but not giving me anything. It's on the correct input (I switched back to my old gfx card with no issues with the supply or other)
I need help quite soon, because my card came in while I was on vacation, so I only have until the 5th of August to send out my rebate information. Or have some sort of solution.
Thanks in advance.

The problem with prebuilt computers is that they don't always suppourt any graphics card, this is quite a common issue. Have you considered buying a new motherboard the one you have is complete garbage you can still use you ram and CPU which will save you money though you should consider a new CPU the bulldozer CPUs are horrible you should get a pile driver CPU atleast like an 8320 or a 6300 atleast

That PSU is not sufficient for your GPU and I recommend replacing it with at least a 500W PSU ASAP. You could also try using a program called Display Driver Uninstaller to completely remove any trace of old drivers before you install your new card, a quick google and you will be able to find that application, I needed to use it when I installed an AMD card after using an Nvidia card.
I would not be surprised if it's the PSU not being able to provide enough power to the GPU, and even if you get it working there is a good chance it will shut down when gaming because the PSU won't be able to provide enough power.

as said above and heres my disclaimer on that issue
some models of store bought computers [dell.hp,acer,ect..] may come with a ''locked or fixed'' bios and may not allow you to change certain hardware as a video card.. this is done to protect them from undue warranty claims and refunds .this is not done to hurt you but to protect them. you really need to see if that upgrade has been proven to work in your model first before you invest money in it .. there are a lot of these threads here at toms to look at some models will allow upgrades and some dont.. and a lot of guys here say ya ya ya when is really no no no...it would be sad you spent $200 on a card that wount post after you installed it as most find out. then get told its your psu and you spend more and end up right back where you are now, but its up to you good luck..
you got to know the the boards in these computers are not like the ones we use to do custom builds witch are open to upgrading with in the boards compatibly . the bios is custom made for there design and just for the parts they authorize to be used on there computers

Make sure the GPU is getting powered by the GPU power cables. See if you can find updated drivers for your GPU on AMD's website instead of the outdated CD.
If its' installed correctly and the drivers are installed. and you've updated your motherboard's bios you might just have to RMA your graphics card.
another thought, you might want to try using different types of cables, for instance a DVI instead of HDMI.
I'm thinking your card is broken though because it sounds like you've done everything right in the installation and troubleshooting. If you bought it from Newegg the RMA process is smooth.

If you read carefully I mentioned I have a new 700W psu. Thanks though.
As for a new motherboard, I was hoping to not have to spend more money, but are there any good cheap options that would work with all of my current pieces? I've bought most of my stuff off Newegg.ca if that can be done..
Thanks.

Ahhh, I'm sorry, I missed that! I highly recommend you try using the Display Driver Uninstaller then.

There is a 6-pin slot for the power which I connected, and I guess I could've mentioned I tried installing drivers from AMD's website as well, after the cd updates failed to work. I thought I had DVI cables, but can't seem to find them, I'll see what I can do to try that out.
Thanks.

It was one of the HPE H8's so I don't think it's your computer limiting what card you use. It might be a good idea to test in on another motherboard but make sure your 30 day return doesn't run out before you have a chance to make sure your GPU isn't broken.
In fact I even added a Tuner onto that mobo and it works. I think HP is good about leaving room to change parts.

hp can reduce the pci-e slot power from the full required 75w to what ever they want it to be [most times 25-35w] this is why most high end card cant work but a low end card [like what most times came in one will] so if the card need the full 75w slot to initialize the card at start up it will fail to do so
but lets hope this or some other reason is not your issue and you can get it going ...

HP's website says it accommodates PCI Express x16 graphics cards. I would assume that means there is room to upgrade.
But they wouldn't just tell you they limit the power on it either.
I found another forum with the exact same problem they said they got a new card and had the same problem, so it's probably your mobo like junkeymonkey said.

look at it like this 7850 needs 150w so hp pci-e = lets say 35w + pii-e 6 pin from psu = 75w now its giving 110w 40w less then the card requires
also I see these high end AMD cards that load up to 280w at full load but just have a 75w pci-e slot + 75w pci-e 6 pin + 150w 8 pin = 300w now if the board or the psu is falling short in anyway things start to degrade from there
this is why I look at boards vrm set up's and psu quality in my builds first

That does makes sense to me.
Are there any suggestions you can make for a cheap board that can cover everything I need it to handle? I can't be pushing out too much more money. But I'll do what I have to.

Best solution
I guess just need to look at the top 5 and decide on one .. not much to choose from am3+ is pretty much a dead end and stock is dwindling

Basically, if I'm going to be replacing half of my stuff, I might just save up and do a huge rehaul. I'll return the card and PSU for now, and buy it all when I can afford a new tower, mobo, cpu etc.
Thanks everyone for what help you could provide.
Cheers

well if you can determine that the card or the psu is not at any fault just box them up until you get all you need for the new build .. I'm using a powercolor 7850 in this now that replaced a sapphire card that was just not too good and it was $100 bucks cheaper then the sapphire and runs circles around it nice frame rates cool it was a surprise just for a cheap ''get by'' card, and now its not a get by ..
