I apologise for the length, but this has been quite a lengthy process
I have been trying again to make this card work over the last 2 days.
Hopefully with a bit more information someone can advise me
To recap. Whenever I install drivers for the card and reboot, I just see a black screen after the Windows logo and Windows doesn't finish booting up.
If I then reboot into safe mode I can remove the drivers using DDU and try again.
I have tried the following things in roughly this order with the following results:
- Reformatted and reinstalled Windows 7 - Same black screen after Windows Logo
- Reformatted and reinstalled Windows 7 with all other drives unplugged - Same black screen after Windows Logo
- Reformatted and installed Windows 8.1 with all other drives unplugged - Same black screen after Windows Logo
- Went back to Windows 7. Tried a multitude of different driver versions and methods of installation (installing only the driver not CCC etc)
- Flashed the BIOS to a newer version
- Tried a different monitor & cable using a different port on the card.
- Installed the drivers manually via device manager and the "have disk" thingy - this actually got me into Windows for about 1 second before I saw the black screen again. Upon subsequent reboots I just saw the black screen as usual.
Now after all those things I started to get a bit creative in the things I tried.
- I first tried a different power cable from the PSU which didn't change anything.
- Unplugged all other fans in the system - no change.
- Removed a stick of RAM - got into Windows for a few seconds and then black screen. - That kind of tipped me off that this could be a hardware fault rather than some sort of weird software clash.
- Swapped the sticks of RAM over so I was using just the other one - a similar sort of result. Trying each stick in different slots also had the same result.
- I then removed my sound card (which has been playing up recently) and holy crap the system booted and remained stable. I rebooted again and it worked again! So I fired up Dark Souls 2 for about 15 minutes and everything seemed fine.
At this point I honestly thought I'd cracked it. During this whole time the PC has been lying down on it side. So I stood the pc up and booted again. Now this is what really bothers me.
The system wouldn't boot at all. It wouldn't even POST. I just see a black screen and after 10 seconds or so it rebooted itself and the same happened again over and over. No amount of plugging in and out of things would change it. I reset the CMOS and it showed the BIOS splash screen then immediately rebooted again.
At this point I kind of gave up and put my 7970 back in - which fired up first time.
During this time also, the onboard network adapter on my motherboard ceased to work anymore.
I don't really know what to think about it. Part of me thinks its the motherboard because of a few recent issues (soundcard intermittently, getting stuck in boot loops as soon as I touch the voltage to overclock, onboard lan breaking). But then I wonder why is it working right now with my 7970? The model of the board is Gigabyte Z68AP-D3.
Then I think could it be my PSU? But its a pretty good PSU and I haven't had it very long. I dont know...I'm at a complete loss now.
I could buy replacements things but I don't really want to unless they are actually broken. OCUK Tech Support assure me that the card was tested as fully working before it was sold to me and I personally don't think its the card at fault - but I could be wrong.
Does anyone have any suggestions or pearls of wisdom for me? Please! lol
