I've gotten a new graphics card, and it seems the drivers have messed up my computer.

Hello,

I've been looking around on the net for awhile now to find solutions. I have done graphic card installations before, but this one just seemed to of failed too many times. I recently brought an asus radeon HD 7770 graphics card since my old one broke, after dusting out my computer, fitting in the new graphics card and then putting the case on and plugging it all back in. Once I did that, the computer loaded perfectly normal, got to the log-in screen, logged in and all fine. The windows detected the new graphics card and instantly downloaded the "driver", of course windows would do this. Didn't have chance to use the CD which came with the card. It then restarted my computer and the first problem came up, was unable to boot normally, ended up having to go into safe mode or the last known configuration. I then downloaded the lastest drivers from the asus website for this model, and once I did that, more problems, my computer would load, once it got past the windows logo screen it would stay on a black screen forever. After seeing people say I should use the display driver uninstaller from Guru3D, I noticed my old driver was still there, uninstalling that and the new one, I used my CD to install the drivers. Went perfectly fine installing them until I got the black screen problem on the reboot. So in the end, some people were saying to once uninstalling the driver, to CCC, so I uninstalled the 7770 driver, used CCC, rebooted my pc, and this is where I've gotten to now.

I am unable to boot the pc normally, or in any of the safe modes if I try any of them I'll get a BSOD, sometimes it'll say bad_pool_header, and then sometimes nothing but stop: 0x00000019. I've tried to use the command prompt chkdsk comes up saying there's no problem, and sfc /scannow comes up saying "There is a system repair pending which requires reboot to complete. Restart windows and run sfc again." So I was told to do sfc /scannow /offbootdir=c:\ /offwindir=c:\ and that comes up with "Windows resource protection could not start the repair system". I've looked but I haven't found any answer to how to fix this without being able to fully log in.

UPDATE:
As of now, normally booting the computer doesn't BSOD me, however it will just stay at the "starting windows" screen and the windows animation repeats.

If you can help please reply, if you need any more details I'm happy enough to give as much as I can.

Thanks,

Treerou..

You should always uninstall the old gfx driver before swapping cards and installing a new driver for the new card.
1) Go to Control Panel and find the current gfx driver and any older driver and uninstall them.
2) Run CCleaner and do the Clean and Registry portions both: http://www.piriform.com/ccleaner
3) Run Driver Sweeper from SAFE MODE: http://www.techspot.com/downloads/4266-driver-sweeper.html
Have it remove any remnants of AMD, NVIDIA, and ATI graphic drivers it finds.
4) Re-boot and install the latest driver for your card and operating system.

Thanks for the reply, I should of gotten my mum to check before she logged in, I wasn't at the computer at the time so I didn't get the chance to uninstall the old one when it went. However, thanks for your solution but as of this moment, I cannot even boot up in safe mode, right now I'm testing safe mode with command prompt, due to it's only freezing on "starting windows" however that's also just froze on the "Loading Windows Files".

Alright, I'm having to download an ISO for the windows I have, once it's done and when I'm back I'll try repairing it with the installation CD, thanks for the help. If anyone else knows a solution I could try aswell - I'd much appreciate it, thanks in advance.
