After GPU Change Pc Stuck On Boot Screen,And thats it....

[shifter5]

Hi!

First of all,sorry for my bad english.

Two days ago I got a new graphics card,(''Gigabyte radeon 7770 OC rev 2.0'')and i cant get it to work.Have read alot of forums traing to find the solution.Tried a lot of suggestions,but no luck...

The problem is that,pc freezes on boot screen,after i connect this video card.
I bought it compleatly new from the store.

Everything is connected properly,i have triple checked everything.

Video card is in pcie slot,power cable connected,video cable connected.Btw my PSU is 750w.
Have updated my bios,same thing happens,updated all chipset drivers,same thing..

When i put my old nvidia 8800gts,pc boots nicely and everything works fine.
But when i try to put radeon 7770,pc just freezes on intel boot screen.

It freezes and i cant access bios and nothing cant be pressed.
When i press,for about five times any key on keyboard.After fifth time pc beeps every time i press something,if i press and hold it beeps,untill i let go.
It stops on intel image where it says press f2 for bios setting.And there is code in right lower corner 5A.
I found what it means,(5A Resetting PATA/SATA bus and all devices).

I Have tied to disconnect HDDs no change...

Another thing,i have tried is to change sata settings in bios.There is like IDE or ACHI.
When i change to ACHI,and power my pc,it cant go till boot screen and freezes on black text:
system memory check 8 procents compleate,press esc to cancel.(same freeze as on boot screen)

But when i power it up the same way again with ACHI,press and hold f2.It accesses the bios,but when i navigate throu menu pages.There's like prints from other bios menu pages bacground color and text.And all bios menu backround is not fully blue,its like bits of blue and black bits from sistem memory check screen.


Pc specs:
CPU: Intel 2 duo q6600 quad
Psu:750w (note,worked nice with nvidia 8800gts,it consumes more power)
2 HDDs (dont remember exactly) Win xp and Win 7 installed.
Old Mother: Desktop Boards DG33BU
Latest bios i could get: bios: DPP3510J.86.0572.2009.0715.2346


I really need your help!
Thank you!

With your old 8800 plugged in, boot to windows and uninstall the GPU's drivers and related progs (like GeForce experience if you have it etc...) Maybe even use something like driver sweeper to completely remove all traces of NVidia drivers. Once that's complete power down, remove 8800gts and install HD 7770. You should be able to boot up to windows and then load the proper drivers for your new GPU.

Hope this helps, Cheers!

Thank you for answer!

But i have allready done it.I uninstalled the drivers and uninstalled the card from device manager.
I have two OS,so i did it from bouth,win xp and win 7.
Gona try,driver sweeper,see if it helps.

Driver sweeper found a lot of nvidia drivers.Removed all nvidia drivers,restarted to recheck if there is no left.Everything is clean.
Tried to boot with 7770,same thing happens...

Crud. Sorry shifter5, it may just be that your motherboard is not compatible with your new GPU. Older, more generic (and I mean no offense by that) motherboards do have issues like that from time to time. Even some name brand mobo's made for pre-builts have those kind of hardware compatibility issues.

A general rule of thumb I use in this kind of situation is if the latest bios was released before the GPU was that's usually the problem. And by general I mean there are many more factors that will come into play but that's the starting point

Thanks,i really appreciate your help!

But now im,kinda lost and i dont know,what should i do..
First i wanted upgrade to nvidia 650ti,than i discovered,650ti Boost.And i was like,650ti boost is way to go.And than i couldnt find in my country for a decent price,was way to overpriced.
So i decidet to go with radeon 7770,because it was almost the same performance as 650ti and i could save some money...

Now,i dont even know,will 650ti work.
It should work with PCI 2.0,like radeon should,but in reality..no.?
What should i do?
I hope i will get my refund for 7770,should i try 650ti?
Cant buy both,mobo and GPU right now...

Nvidia 8800gts served me really well for like7 years,untill it started to make artifacts,but it still boots.
Yeah its a long time no upgrade ha.
Good that i still have VGA output in old mobo.

Thanks!

It's hard to say if the 650Ti would work shifter5. I would just wait and save up for a new CPU+motherboard+GPU+RAM. It's not really worth finding another motherboard since the 775 socket is dead and is becoming outdated, even though it isn't now, it will be in the next year or two (so why invest in something that is not going to meet your needs soon is what I'm getting at).

Just to be clear, it isn't the fact that it is a PCIE 2.0 slot on the motherboard that makes it incompatible. Graphics cards are downward compatible (so GPU PCIE 3.0 would work on 2.0 or 1.0 slot). It has to do with utilization and communication instruction set(s) that the motherboard uses to work the GPU. A bios update MAY have fixed it if the manufacturer had bothered to make one, but they seem to have abandoned it do to age and possibly chipset limitations.

I know how you feel with this whole situation of wanting to upgrade. I was in nearly the same position myself last December.

I had an E8400 3.0GHz in a Dell OptiPlex 760 (not as good as your rig but still the LGA 775 socket ) and I bought my GTX 650Ti. Problem is that the GPU is double slot (takes an extra slot for cooling) and the case would only fit single slot.
I also purchased more DDR2 RAM (8GB 800MHz) and my EVO SSD. When I got ready to install everything I WAS going to modify the case so I could still use the 650Ti (not knowing if the motherboard would support it) and realized how important it was for me to always have a working computer. So I put in an old NVidia 8400GS and the RAM and decided to build the computer I have now.

All that to say, sometimes when you are looking for just a little bit more performance you need to step back and look at exactly what you will need to do the upgrade and see just how much it will cost vs. build something new.

Whew! That was long. SO all that to say I'd recommend just tolerating what you have now while you save up to make the move to a (basically) whole new computer. Since your 8800GTS is failing you may want to consider getting something like a 8400GS (if available where you are). It will most certainly work (although nowhere near as good performance) and will be pretty cheap, to hold you over while you save up.
Or you could really just "bite the bullet" and put up with onboard graphics and save quickly

Again I'm really sorry this upgrade didn't work out for you and wish you the best of luck with whichever upgrade path you take.

Yeah,you are right.Its time for a new build!

Thank you for your help and advices Dom_79,the best support!

With best regards,
shifter5.
