I recently purchased an HIS 2GB GDDR5 PCIe 3.0 Fan Radeon HD 7850.

I installed it several times before taking it to BestBuy's Geeksquad. I have done quite a bit of research but it seems that everything I read is quite contradicting.

I have an Angelica 1.2 REV. mobo with a Radeon HD 7450 with 10GB ram and a 6100 FX series CPU (Ialso replaced my 300W PS with an 800W PS).

now after installing my new 7850 everything on the inside of my PC looked correct and in running order including my new GPU's lights and fans BUT my monitor was non responsive.

Now after about 20+ careful instalations and talks with HIS customer support I decided to take my PC to BestBuy and have them figure it out. After 2 weeks they figured out as much as I did. they think it might have something to do with the new UEFI BIOS, or that my current GPU is 2.0 PCIe and my new one is 3.0.

If all this is true its been hard to find a mobo that is Micro ATX, AMD 970, AM3+, with MIN. 1330 MHZ, and PCIe 3.0.

Any help?

I agree with k1114. PCI-Express is completely backwards-compatible both ways. You could install a PCI-Express 3.0 card in a PCI-Express 1.0 slot and it would still run (at PCI-Express 1.0 speed, but it would work). As an aside, I would NEVER buy a card from BestBuy. One tech working at Tiger Direct or Canada Computers has more expertise than three entire Geek Squads. I once overheard a "Geek" at BestBuy telling someone that Radeons work better with AMD CPUs and GeForce cards work better with Intel CPUs which as most of us on this site know, is complete BS. Sometimes I think that the only requirement they have for their "Geeks" is the ability to turn a screwdriver. I mean, if they tried telling me that the problem is PCIe3 in a...

I mean, if they tried telling me that the problem is PCIe3 in a PCIe2 slot when all modern cards are PCIe3 but 90% of motherboards are PCIe2... Well, I can't use that kind of language on this site....LOL

I never bought the GPU from BestBuy, I got it off NewEgg. I brought the PC into BestBuy cause I pretty much gave up trying to figure it out. and I kinda gathered that I knew more about computers than they did but they have more resources than I do.

I looked into it a bit more and found that HP make a proprietary mobo that limits what you can upgrade on your store bought machines. Now I have to figure out if the CPU is Proprietary or not.

I have gone to 3 different computer repair places and even BestBuys Geeksquad and no one can figure it out. My old GPU works in it just fine and we have pluged my new GPU into multipul different PCs and and it works fine. I do have a Security option in bios for the PCIe slot which has me puzzled. but when I disable the slot security it saves, restarts, but everything goes blank and not even the old GPU will work. That was remedied by removing th CMOS battery for a while.

Well, Come to find out the motherboard was proprietary. only the graphics card that came with the computer will work with it... We put every GPU known to man in the damn thing and none of them worked except the one that came with it. So... time to build my own computer.
 
I have the same motherboard but its in a computer that looks like it was refurbished by newegg and sold without the HP name. IT says its a heavy metal, so maybe thats who refurbished it. But my gpu is a AMD Radeon HD 7570. Is that what card yours came with? Also how did you find out about the motherboard being proprietary. I don't really have a need to upgrade the gpu yet but I am hoping I have the option in the future if I get into some intense gaming or something.

Although others may have solved this issue that way, we, the owners of this mobo, cannot. The option simply isnt there. Disabling secureboot changes nothing on my behalf and the all you can do with legacy mode is rearrange the order of which devices it boots first. I know this post is old the problem is still here. Im trying to install a XFX R7 240 and am receiving no signal however the original card still. I dont have integrated graphics so that options out the window. Everyone is saying pci-e 3.0 cards will work on this mobo but one newegg review said he couldnt get that card to work in any of his pci-e 2.0 computers, and he has 20 of them
