So i was tinkering with my graphics card settings under the catalyst control pannel. I accidentally messed with it too much and now i have a D-SUB out of range error. it says 68. 0khz / 60Hz. So i booted windows in low res mode, and un-installed my driver software. Now im trying to re-install the software and right when it should be done installing I get the D-SUB error again. I then restart my computer and it boots but, the driver software is still uninstalled. I tried to re-install but i keep getting the same DSUB ERROR

actually when it boots, it goes back to DSUB error. I have to press f8 and open it up in low res mode to even get back to my desktop

take your gpu out so that you re activate mobo video output, Uninstall catylyst completely and then re intsll a fresh copy this will default any of the changes you have made. After you have catylys working properly. Then put your gpu back in.

sorry let me be clearer. after disconnecting the gpu use your mobo's video output to do the uninstalling and reinstalling.

Im sorry but im relatively new with computer assembly and hardware, I dont know where that is. Are you talking about plugging in the D-SUB cable into the motherboard? Sorry that i don't know this

Yes when the gpu is powered up it disabled video output form the motherboard but you have messed up your gpu drivers. To fix this take your gpu out. This re enabled your motherboards video port. i am assuming this is dsub. so plug your monitor into this and you should get a video feed. Uninstall all your catalyst stuff and do a fresh install. This should clear the messed up drivers and let your gpu work again properly.
