Okay to make quick, I'll ask this, Why isn't my graphics card ,(Sapphire Radeon R7 240 1 GB) working with my desktop!? Desktop is a (Compaq Presario CQ5500F)... Things to know beforehand: I replaced the CPU with an (AMD Phenom X4 9750) and the PSU with an 800W PSU. I'll be MORE THAN WILLING to provide more information if what I shared is insufficient to your understanding on why this graphics card isn't working. I mean it fits in its slot and the little fan even spins... I'm really frustrated and just want to game it.

I've removed the integrated graphics already and seated the graphics card properly.
Here's the motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?cc=dk&lc=da&dlc=da&docname=c01925534#N117

His model does support GFX card ---ya the one hp put in it

dude there hundreds of these threads here at toms and I just went to hp site on his computer and for what I see just memory is allowed .. that's the way these store bought computers are. as I said these are not nowhere near the type of open motherboards like we buy from asus or whoever I really hope he gets it working but just like the rest I don't hold my breath on that.. now I sent him a trick to try that can fool the bios into accepting the card may work may not ... now I said what I had to on this as I try to do others in this mess and some have taken theres to a shop just to find what I said above is true . all I can say now is I hope he finds good luck and does...

none taken. plugged the VGA cable inside but no picture. I don't know what you mean 'enabled in BIOS'. I've installed the disk that it came with but that doesn't work. maybe I'm doing something wrong? I can't even find the driver info on my computer after I've installed the driver.

When you turn pc on, keep pressing F10 until your PC goes into the BIOS screen, browse through the menus until you find an option that says 'use onboard vga / use pci-e'. Make sure its set to PCI-E. Remember it may not say exactly that but something similar. Once you save the settings your screen may go black, don't worry. Unplug VGA cable from your motherboard and plug it into your GFX card and reboot.

~ Is the card showing in device manager as it is?

some models of store bought computers [dell.hp,acer,ect..] may come with a ''locked'' 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

Thx for the feedback, so is there a way to bypass this 'lock' feature? or should I just find a whole new board?

So before it was set to what, onboard graphics?? You saved the BIOS settings, plugged the display cable into your graphics card and it's still no picture? Is this in windows only or boot screen?

When you turn the PC on with the graphics card cable plugged in, does the Compaq logo show? Or nothing at all? Also try a different monitor, or try using the DVI or HDMI connectors on back if you can.

If you go back into bios is it still set or has it changed back? You have to be sure to save it, then turn off pc, attach cable and try again.

I've made sure and saved it. Used a different monitor using the hdmi cable instead but nothing... I think the 'lock' feature may actually be causing this... It does sound plausible when you think about store warranties and all the bs that comes with that.

Whats relevant? Upgraded CPU is working for him. 2nd link is unrelated to our problem, and the OP of that post solved his own problem anyway. Although the 2nd post does point to something interesting.

~How much RAM is installed on your PC?

Shop bought Compaq Presario CQ5500F bought in 2010 fitted with aftermarket Radeon HD 5450, Worked fine.

Do you see the Compaq logo with Your graphics card, or nothing at all? Do you have another card you can try?

It seems that this motherboard you have does support cards but theres A LOT of different revisions, with no BIOS updates. The board is perfectly capable of Running a PCI-E 3.0 but requires the later revisions of which you can't upgrade too. Which is why i'm seeing some running newer cards (With newer BIOS), and others (Like my old family PC) with the 5450 running fine.

I'm not saying junkey is incorrect but just with this exact PC it does support Cards, but seems to be picky on what you put in it.

ya the board supports but hp controls what is supported they manipulate ''there'' bios to what they want and how the board will be used lets take that pci slot and say hp don't want it to get full power to it to feed cards over there set voltage limit so with there little get by home/office card they put in it it works fine but you want a nice gaming card for it the slot may not provide the full pci voltage for it and now you got a fans spinning and looks and sounds like its on but you got that black screen cause you not getting the juice to fully power the card... hp and them got it all figured out they don't want you to upgrade they want you to but there new better than the one you got computer that's how they make there money ..

I'm done here your on your own I said what need to be said on this so I really hope I'm wrong and you get it going ...... good luck
