Well as the title says I recently bought this new card and my PC meets the minimum specs but when I turn it on the fans kick in on the PC but it won't even post. If I unplug the eight pin power connector it beeps twice but goes no further.

My specs are:

Asus M5A88-M Motherboard
8gig of DDR3 Ram
AMD FX-6100 CPU 3.3ghz
My PSU is something like 800w but certainly powerful enough for this card.

I've tried changing the bios settings to make it use PCIe first but still nothing, no post at all.

Any ideas?
 
Solution
What is your EXACT power supply model number? You will find a label somewhere on the PSU itself with the specifications and model listed. 800w, means nothing. There are 800w units out there that can't adequately sustain 450w and even a good 800w unit could have problems. The biggest red flag I see is that there are actually VERY few, if any, 800w units still being made that were of any decent quality at all. That means it's either likely a poor quality unit OR it's very old. In either case, it could absolutely be related to your problem.

It might NOT be, but it certainly COULD be and you shouldn't assume due to a paper specification that the unit is either capable or healthy.

As far as the legacy bios setting is concerned, if you have...

Bread Board your PC:

Take out ever part and try run it with, start with:
- CPU + Cooler
- Motherboard
- 1 Stick of ram
- PSU

Try get a post with just these components (use the on board graphics), if this works add a stick of ram and see if that affects anything. If that works add the GPU and see again. Make sure everything is plugged in correctly and fully (pushed all the way down and such).

2 beeps usually is a memory error, so start by re-seating and trying them in different RAM slots, if that fails try 1 stick and so on.

Good luck and let me know if you need anymore help :)

Thanks for your reply I will try that. The PC boots just fine with the onboard GFX and I tried updating the mobo bios too. I'll get it to bare basics soon and let you know. :)

Well the PC boots and posts just fine with whichever combination I have hardware wise until I plug this new card in. There's no beeps, no post and no boot but there is power. The company are saying I'll have to have them send it off for testing before they will replace it and I am fearing they will say it's fine and I'll be stuck with it.

I don't know what else I can try because it can't be software based as it doesn't even reach post and unless I am missing something it's pointing to the card, I think.

EDIT - Well I took the card back and they tested it and it is working fine so now I am wondering if my motherboard is simply too old for the card?

Try one more thing before your reset.

If you have isolated the problem to the GPU then try this setup.

-CPU + Cooler
-One Stick Of Ram
-PSU
-GPU (Make sure you can change PCIE slots if possible on your mobo, its fully pushed into the slot, and the PSU is plugged into the card properly as well).

Before you boot however, take your CMOS battery (silver circle) out of the motherboard. Leave it out of the motherboard for a minute or two (go have a cup of tea or something). After a while, put the CMOS battery back in and then try again. If this doesn't work, i'm 99 percent sure its the GPU that's at fault.

Besides, you have tried everything that you can do on your end to fix and diagnose this issue. I had a similar problem a few years back with some RAM I got, I just detailed my process of troubleshooting and they didn't question much else so dont worry about it :) Good luck and I wish you the best, let me know what else happens :)

Hi just saw your edit:

If it works fine then try the CMOS reset. Getting the GPU to work with the bare minimum outside influences is your current goal. It could be a dead slot in your motherboard etc. It wouldn't be because your motherboard is too old. I ran that exact setup, except with an FX-8350 for 2 years!

Nope the ah heck won't post at all under any combination of parts installed. The one thing I'm thinking is when the old card burnt out it's screwed the PCIe slot as well. I can't think what else it could be at this stage so I'm going to try save up and buy a mobo/CPU combo which I'll check deffo works with it.
Unless you can think of anything else to try we might as well call this closed. Thanks for your help my friend, we tried at least. :)

Respect and peace bro.

HA just looked up my MOBO. It says it takes PCIe 2.0 and my card is 3.0 so could that be the issue? If not then it must be a burnt out socket.

OK I have my eye on this bundle. In all honesty even with my last 2GB GeForce 660 I think the PC was bottlenecking and especially when I had an 8GB Radeon for a while so I would think my new card and older hardware would cause me issues later on anyway so I was due an upgrade for sure.
With you being clued up on hardware etc would you say this is a good MOBO and CPU combo to go with this new card and also will my current ram work in it? My RAM is 8GB of G.Skill RipjawsX F3-12800CL9D- (I think that was what it said on it when I took it out earlier)

AMD FX-8350 8 Core 4.0GHz Gigabyte GA-78LMT-USB3 R2 Motherboard Bundle

I don't have any money so if I can gather the funds for that mobo and CPU and my ram will work in it I'll be made up. It took me a year to save up for the GFC card and my damn mobo won't accept it lol.

Thanks again buddy.
 
I've seen about 50 DOA RX 580 threads, myself, alone, here on this site alone, since December, so I'd seriously make the attempt to try a DIFFERENT card in the same system that is KNOWN to be working fine in another machine.

Did you actually SEE them test that card when you took it back? If so, then I'd agree you may have a motherboard issue but I wouldn't assume it. That board is certainly a UEFI board and is not too old for that graphics card. It may however need to have a newer bios version than what is currently installed if one is available for it. It's also possible that you may need to do a hard reset of the CMOS WITH the card installed, as follows:

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

If the system will not POST after resetting the CMOS, then there IS a problem with SOMETHING hardware related.

I think when the old GFX card burnt out it took the socket with it and I don't have another card to try. I think I'm just going to grab a new mobo from the same place I bought the card and take details of my hardware and see that they say it will all work. Seems like the only issue with this new board I'm after will be configuring it to run my higher speed ram but it's doable. If it doesn't post on this new board then I'll be demending my money back.

The only thing left to try is the legacy thing but I have no idea how, is that setting in the bios cos I looked for anything to do with it and couldn't locate it. Also I upgraded to the latest bios too.

I'll search for a vid on how to change the legacy setting thing.

Thank you.

EDIT - Hm I see a lot of comflicting info about this legacy stuff for windows 7, talking about having to reinstall windows if I enable it etc. This new mobo is looking more and more tempting.

It might NOT be, but it certainly COULD be and you shouldn't assume due to a paper specification that the unit is either capable or healthy.

As far as the legacy bios setting is concerned, if you have Windows 7, you MUST have the BIOS configured to CSM enabled and "Other OS" rather than the "Windows 8/10" UEFI setting. Windows 7 is a legacy operating system. Honestly, you need to seriously consider ditching it and upgrading to Windows 10 which is far superior anyhow. Obviously, to do that properly you'd need to do a clean install of Windows so I wouldn't necessarily worry about it right now until you figure out and resolve your current issue, but I would certainly plan to do it at some point.

There are too many reasons to list, not least of which is much better driver support and memory management, besides the fact that come next December, Windows 7 is 100% done anyhow. There will be no further support, not even for critical security updates, after that.

I'll be honest about the motherboard, I think it's a waste of money. If you're going to spend money on a new motherboard, it should be something a lot newer, but then of course you're going to also need a compatible CPU and memory as well. I just can't see recommending the purchase of a motherboard for a platform that was weak to begin with, plus is about 5 or more years old. It's money that would be better spent towards an upgrade, not a sidegrade, but you gotta do what you gotta do I guess.
