OK. First off hello. Second, thank you to anyone that reads this. And third, I could not find anything with the search function to fix my problem so sorry.

Alright, well my problem is as follows. I can see my bios loading and the Windows logo then it just goes black. I can load safe mode, safe mode with networking (this is how I am posting this) and safe mode with command prompt. I have no other safe modes. I can load everything fine if I switch to a TV. I can also change my resolution to whatever from there even to something that I know works on my monitor. Switching it back doesn't fix anything.

The cause. I was trying to change settings in my AMD Vision Engine Control Center to allow Dark Souls II to work. Going through several options only made my screen either flicker or go multi-colored. No biggie. But my last ditch effort was to alter the refresh rate AND resolution from the default 60 Hz 1920 x 1080 to 75 Hz 1280 x 720. Well that made my screen go black.

So now I figured I would change it through safe mode. Yeah, that doesn't work. Alright then. I tried reverting to previous drivers. Nope. Next I tried uninstalling all the AMD stuff and starting from scratch. Nothing. Hooking to an HD TV set at my native monitor resolution. Not happening. None of the changes made effect anything but what they are changed on.

At this point I don't know what to do. I don't have restore points or anything that could take me back to a working state. No longer own a windows disk. Too tired at this moment to list anything else I fail at.

If there is anyone that can give me a simple fix or tell me where Windows or the AMD programs might store a profile per monitor/tv so I can delete this I would be immensely grateful.

*Edit* < sorry btw

Okay, there is a very very small chance, that while you are in windows, turning the monitor off and then back on again will reset the driver. (the problem I think, is your monitor driver, not your GPU driver)

Also you can try enabling low-resolution Video (640 x 480) in the Windows 7 Advanced Boot Options(F8)

That seems like it would work but my graphics card only has one HDMI port and I do not have any DVI converters.

Well I had been hitting F8 all night. I only had 3 options and all were safe mode. For whatever reason I hard reset my computer and this time F8 brought up the advanced boot options you mentioned. Loaded it up on low res and viola! Thank you.

You need to press F8 many times at startup then select low resolution
