Hey guys,

I recently upgraded my graphics card.My old one was a AMD Radeon HD 6570 and now the new one is a Diamon AMD Radeon HD 7770 Ghz Edition.I've done everything correctly(Installing the card+Installing the latest driver from the website),but whenever I start any game up,it would play for about 3-4 seconds,freeze and crash the game.Sometimes it even restarts the computer.

My PC Specs are:

Windows 7 Ultimate(64 bit)
Diamon AMD Radeon HD 7770
4GB Ram
AMD Athlon X2 250 3.0Ghz Processor
500W Power supply(Yes it does have a 6 pin cable for the graphics card)

Any help would be appreciated. :) 

Thanks.

Express uninstall the driver then re-install it again. Is there any sound loop during freeze?

Well you got a nice card (series at least) but many people have trouble with Diamond brand.

I am also thinking that there is video card issue.

Nope,no sound at all.Only sound I get is the PC restarting sound >.< and yes,I've tried that many times:Uninstalling the drivers and re-installing them again(Express mode).

Then it is the gpu that is faulty. Most of the time game freeze due to gpu issue.

@ akshayghai29785, Is it happen while gaming? If your driver is up to date then its the faulty gpu.

Negative.I went to the store where I got the card from,explained them the issue and they exchanged it with another one.Came home with the new one,installed it.Still the same problem.

Can you check with your old one? Make sure mobo's pci-e slot is good.
October 3, 2012 12:50:35 PM

Yep,I just did,uninstalled the 7770's drivers,shut down my pc.Took it out,put my 6570 in,started,installed latest driver,restarted.Results: Works fine. No problems with this one

What is you mobo? Is it support pci-e 1.1 or 2.0?
October 3, 2012 5:09:22 PM

Yes,it supports 2.0 PCI. It's a Motherboard from GIGABYTE S-Series GA-M68M-S2P

Then there is no problem with mobo. Can you check the new 7770 to another pc? Looks like the new one is also bad.
October 3, 2012 6:02:18 PM

I'll give it a try on my friend's pc.I'll let you know what's going on.
October 3, 2012 9:59:13 PM

I tried it on my friend's PC.Results: Works perfectly fine.

I think you should give a fresh installation of os. As 6570 is running fine then there should be no problem with system. See if you have luck.

I have a HD 7770 too, and I can tell its a great card! :) 

In this case, I can probably think that it could be a Accidental Overclock of the GPU or the PCI-E slot.
Or it could just be a bad Power Supply. (It has to be very bad since I have a 300W PSU using a 6-Pin adapter and it works fine)

FYI,I installed windows 7 two days ago,and I have the card's issue since the past week.Even when I had Windows XP,I had the same problem.

Overclocking isn't done in Windows, it is done in the BIOS. But assuming what you told me, you shouldn't had gone in the BIOS anyway...
Then I can only suppose that you have a bad Power Supply...

I would be surprised...really.I also checked the minimum requirements for this card.It sais it needs a 450W power supply at least.So I don't really think it would be my power supply the problem.

Its not about watt, its about quality. Maybe your psu is bad quality. Which brand it is?
October 7, 2012 3:24:04 AM

Its a MIOS model: 400U

So I guess that there's no solution to this?

I am not sure about psu quality. Never heard of it. Both your mobo and gpu is fine. You can try with decent psu. Can you check your system with your friend's psu you checked before?
October 11, 2012 12:22:31 AM

Nevermind guys,it finally worked.This time I downloaded the driver with a BIOS update,but I still got a problem.Switching from the 6570 to the 7770 wasn't really a difference for me...I mean,I get the same amount of FPS and I still can't really record with fraps without lag.Maybe it's because of my dual core processor that my card isn't giving it's 100%? Do I need a better power supply or a quad or more core processor?

By the way,thanks for helping me.

If it can run then the PSU can give it enough power. As for the processor that's more likely the issue.

Good for you, you solve the problem.

You cpu is bottlenecking your gpu. Its not giving its 100%. To check how many % of gpu you are using, use GPU-Z soft.

But non-cpu intensive games will give you full performance boost of 7770 like Dirt3/Alan Wake/BF3 in SP.

What is your mobo? You can upgrade to a phenom ii x4 cpu which will not bottleneck your gpu and will be very good for you.
