Hi! I recently purchased a Sapphire HD 7870 for my prebuilt computer. I plugged in everything and now when I try to boot up my computer it just beeps. 2 short beeps and 1 long beep. My computer is http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en...[1] with the nvidia gtx 260 and 9gb ram and the 2.66 i7.
Should I uninstall completely the nvidia drivers? It has some drivers left over, would that interfere with the card working? i plugged in the HD 7870 and the fans are spinning and its working just fine. Any help on addressing the beeping? Should I install the AMD drivers before plugging it in? Any help would be appreciated.
i've also tried plugging in my previous graphics card and it worked just fine.

My best guess would be that the 460w PSU that comes with that pre-built system is just not enough to push that new GPU. The PSU's that come with most pre-built systems are just enough to run the system with the hardware they come with and that is about it. You need to get a better PSU from a good company like Corsair Antec XFX Seasonic PC Power & Cooling.

Check with the paper work that came with your PC it should tell you what the beep codes really mean but my best guess would be something like graphics hardware failure which could mean not enough power. One last thing did you plug the PCI-E PEG connectors into the GPU?

Better to completely eliminate drivers with Driver Cleaner Pro before changing the video card to avoid drivers issues while on windows, install drivers after booting with the new GPU.

Your issue however is at the POST so no drivers at that point, the 2 short beeps and 1 long beep is a signal of a video card problem, you sure you plugged the two 2x6 PCI-E power connectors?

Also, the info on your PC says it has a 460w PSU, maybe it doesn't have enough amperage on the +12V rail to support your GPU.

I agree with the others. Be sure that all the correct power plugs are connected from the PSU to the GPU. However, I'm pretty sure your 460w PSU might not be providing enough juice

The GPU "requires" a 500W minimum. But, check to be sure that you have power plugged into BOTH 6 pin power ports.

WAIT! You need to have both PCI-E connectors PLUGGED IN? I would need to disassmble my PSU then to try to attach the extra cords..I'm not quite sure on how to do that. Both fans are spinning already though when I plugged in the graphics card, wouldn't it mean that is it enough juice? Excuse me , I'ma total noob t_t

Edit: I plugged in One connector but I need to have both connected?

sounds like you will need to get a new power supply.

Yes you need to have both PCIE cables connected to power the card correctly but only running on a 460w HP standard PSU will not be enough power to the run that particular card as it probably does not have the required amps on the +12v rail to supply it enough power.

I would recommend a power supply upgrade of atleast 550w with an 80+ silver certified output from a quality branded power supply, Antec,Corsair,OCZ,Seasonic are good ones, Make sure they have atleast 32 or above amps on the +12v rails and is going to fit in your pc case

Nice! I got it to work! With just the 460WPSU. I plugged in both pci-e and it works. I'm just going to hope it doesnt burn down.

Nice mate good stuff and i had a bit of a laugh at i hope it doesn't burn down lol but keep an eye on things still as running on a generic PSU is not really recommended for a mid-high end card best of luck with everything and happy gaming :)

Thank you sir! Should I keep an eye out for warning signs that the PSU isn't keeping up? I'm really not looking forward to replacing the PSU any time soon unless forced to. I'm floating around 40~c on idle, hopefully thats normal.

Keep an eye on it means if you start to get computer lockups/restarts/blue screens that would be a good indication your psu isn't handling your card and requires an upgrade but for now play games and do tasks as you would normally.

40c on idle would be normal on that card as your case would have limited fans if any being a HP system. Even my 7870 oc sits around that temp but never passes 65c but my case has plenty of airflow just keep an eye on temps when gaming using a program called HWMonitor and you should be fine :)

Thank you once again for the reply. I just played a game of League of Legends and the max temp was 55 and avged around 50~. I am going to try to try bf4 now. ;D Fingers crossed.

Also please note that just because it is working with the default PSU does not mean it will keep working under load. And if that PSU goes it could very easily take the whole system with it CPU RAM GPU all could be destroyed if that PSU blows. Just something to keep in mind.
