Need help with 7770 Driver

[Overly_AttachedGamer]

Well... I've bought an EVGA 2Gb GTX680 recently, and I went to install it in my rig of -
AMD fx4170 4.2Ghz
Gigabyte GA 78LMT-USB3
Artic MPS550 550W
former GPU (problem) MSI 7770 1Gb
And so forth; I deleted the old GPU's driver as it told me to in the EVGA manual, I disconnected everything, got ready for the swap & put in the 680, only to realise I didn't yet have the 8 pin connector, so I unplugged it after an attempt to find enough connectors to make one, and re-installed my 7770 & my pc refused to load up the login screen, it just says "Input not support" can you guys help?

Check your cable between the video card and your monitor. Power-cycling the monitor may help.
The current (12.x) AMD drivers have an OpenCL bug as well; I'm using the Beta (13.3?) drivers without difficulty.
I don't think your current PSU can handle a GTX680.
If you have this: http://www.kitguru.net/desktop-pc/gaming-rig/luke-hill/cyberpower-gaming-battalion-502-windows-8-pc-review-fx-4170-radeon-7770/
...then no, it can't. Based on its 20GBP price on Amazon, and the fact that it has no PCIe power cables, I'm guessing the PSU is a piece of cheap Chinese junk with a liar-label slapped on it.

^ What Onus has said


You haven't uninstalled all the remnants of the driver yet.

Follow the steps in that link or there are many other step by step instructions out there but the one above is quite thorough.

My apologies, I've made a mistake - I didnt manage to re-install my 7770, I re-fitted it* however I didnt install the drivers, I didnt get the chance as it comes up saying "input not support" before I get the chance to log-in.

Apart from an updated case, yeah that's my PC, I'm getting a modular PSU anyway, that's my next purchase.

Make sure it is a quality PSU, such as something made by Seasonic, or Enermax/LEPA (they make a lot of modulars).

Boot into safe mode first and then try.

 

[Onus]

I don't think he gets any signal.
OP, if you do see a POST screen, pressing F8 repeatedly as it starts to boot Windows should give you a chance to go into Safe mode.

Ambiguous. Do you get display during any part of the boot process?
