Hi, one week ago I have bought an GPU - Gigabyte Radeon RX 460 Windforce OC - which I installed on my - ASRock H81M-VG4(BIOS P1.50) - motherboard.

MOBO - http://www.asrock.com/mb/Intel/H81M-VG4/

GPU - http://www.gigabyte.com/Graphics-Card/GV-RX460WF2OC-2GD

The problem is while I boot the computer using the RX 460.

It won't show the POST Screen and won't boot to windows loading screen(Its simply giving me a black screen and stay that way) unless I swap the RX 460 with my old GT 630.

While using the RX 460, computer shuts down instantly when pressing the power button (usually I think it should take around 4-5 seconds).

After I changed the RX 460 with the GT 630, It succesfully shows the POST Screen and I can use the BIOS so I can go to CSM and disable it then shut down the computer, remove the GT 630 from the PCIe slot, put the RX 460 back into the PCIe slot and it kinda works.

It does boot with CSM Disabled.

When it boots with CSM Disabled I hear 3-4 beeps and after those beeps a message shows up on the screen saying :

When I took this picture the bios version was P1.30 I succesfully updated it to P1.50 yesterday.

Please can you guys help me do something about this? I've been changing GPU's between GT 630 and RX 460 for 1 week.

It looks like when you set CSM to off on the old card and then shut down and swap in the new one the board flags an error that is related to the old GPU. The RX 460 does support GOP where the GT 630 may not (some do some don't). If you have not tried to clear CMOS yet I would do so and post back. 

I don't know if I installed Windows 10 for UEFI, where do I check that?

Would installing Windows 7 fix all this problems ?

No, not installed in EFI/UEFI mode it won't be.



Is this a new build, or one that's been running fine on you H81M-VG4 motherboard for a while now?

These are the partitions I have. I don't see any EFI System Partition so I guess its not EFI.

It's a build that have been working fine with the H81M-VG4 untill I changed the GPU.

If installing the Windows in UEFI mode would fix the problem, how can I do it ?

So, before I reinstall the windows I must clear the bios, right? should I remove the CMOS battery and put it back in or just Load UEFI Default in the BIOS ?

I wouldn't say that a 15$ PSU is adequate  gonna change it most probably on friday or early with a Sirtec - High Power EP-500BR II

could this be an accomplice too ?

Accomplice? If it is not the outright cause of your issues I will be amazed.

Yea. Toss that Delux one in the garbage.

Yeah that's what I plan to do with it, Toss it into the garbage.

But would Sirtec - High Power EP-500BR II do its job?

Are there any other decent PSU's in the 45-50$ price range?

How about a Corsair NEW VS Series VS550 or Super Flower SF-550K12XP v2 550W ?

Edit: I'm trying to make a Windows 7 bootable USB Stick and I don't know what to choose between these that would eventually boot with my new GPU without disabling CSM in the bios using the old GPU.

The Corsair would probably be the better bet. 

Should I reinstall the windows now using that GPT partition scheme or wait for the PSU and see what happens with it?

Thanks for all the help so far, see y'all in a week or so.

Where I live those are the available PSU in my price range.

Corsair NEW SERIES VS550

Corsair Builder Series CX430

Super Flower SF-550P12XP 550W

Super Flower SF-550K12XP v2 550W

FSP HYPER 500W

Well, I changed my mind and I probably ain't gonna buy that Sirtec anymore.

Instead I would've think of Corsair Builder Series CX430 ->

What do you think about it ? Could the CX430 handle it without any problem? the system is being used mostly for gaming(not the most demanding games out there) (usually I spend like 5-6 hours playing games)

Is the PSU better than any of the above and if it isn't which one from the above list should I buy ?

Full PC Specs (might not be the best CPU ever, but still gets the job done in one way or another);

I put the specs here so you guys can make an idea if the CX430 would be enough for it.

I checked if my HDD could support GPT, but seems like it only supports MBR, is it fine if I would go MBR UEFI partition scheme ?

GPT works on just about any SATA drive, I used it on an old 5200rpm 2.5" SATA II laptop drive without any issues for an HTPC I built a while back.

I've been using the DELUX 'PSU' for 7-8 years. 

I never bought a PSU before(DELUX came with the case) and if I buy one I want it to be atleast a decent quality one.

I wanna say that I reinstalled my windows using GPT partition scheme for UEFI and it works like a charm. Thank you for all the answers, you guys are awesome.

also I bought a Seasonic S12II-520 Bronze I hope it is a good PSU, I'm also curious if that PSU can handle an i5-4590 + RX 460 and if the CPU is compatible with my ASRock H81M-VG4 (regarding BIOS compatibility).

Awesome to hear and thank you

PERFECT, Seasonic are one of the best money can buy, even their cheaper units are great.

How about i3 4170 + RX 460? would it slightly bottleneck? and its the i3 a decent CPU for my system? Most of the time I use my PC for gaming.

In most games however the i3 is quite capable and shouldn't bottleneck the RX 460 much, if at all. The problems start with games like GTA 5 that are exceedingly CPU heavy and thrive on higher core counts. What's worse is that with Ryzen becoming available tomorrow and 6 core 12 thread variants coming a little later in the year we are going to see a LOT more games taking advantage of higher core counts which could see the i3 go the way of the pentium and other dual cores (inadequate). 

Honestly, I would not recommend a dual core to anyone at this juncture unless it was for an ultra budget build in which case I would suggest an H110 motherboard (with a Kaby Lake supporting BIOS) and a hyperthreaded Kaby Lake pentium. This combo would be cheap, offer almost identical performance to Haswell i3s and be upgradable to an i5 or i7 later on. 

So to answer your question:

No, don't waste your money on the i3, you will regret it. You will be by far better off with a lower clocked i5. Now if you are willing to wait and save a little longer we should see Ryzen 4 and 6 core parts at some point this year as well as price drops from intel when that happens. If you need something now do yourself a favor and save a little more to get an i5.

Moral of the story, save up a little longer and don't cheap out on core components (including PSU). It is way better to be stuck with a piece of old junk for a month longer while you save up than have wasted money on another piece of junk that will disappoint you in less than 6 months.
