Hello All, hopefully you can help....I have a feeling I have bricked my HD4870
I was using riva tuner to underclock my GPU- I wanted to get the settings as low as possible to silence my PC while browsing the internet and doing less intensive tasks.
I moved the memory frequency slider to the minimum setting and applied it- after that, the screen flashed and since then, I have not been able to boot into Windows (correction- the computer boots, but there are blocks all over the screen so I cannot see the desktop) I can boot into safe mode, but there are 'lines' all over the screen, so it's difficult to see what's going on.
I wouldn't usually be worried, but blocks and lines are appearing all over the screen, even when POSTing....have I damaged my card?
I cannot get into the Catalyst Control Center because it says it cannot load the driver (although Windows does say a driver is present) If I try and download the driver to install I'm unable to do so because safe mode won't allow me to install....basically, I'm after a way of installing the driver so I can get into the CCC- once there, I hope to be able to reset the frequencies to maybe get things back to normal.
It's ironic that I appear to have bricked my GPU by under clocking...!
Any help really would be appreciated, otherwise I have just made a big £140 mistake!
