He was using his PC fine till after he installed catalyst 9.8 for his HD4850, but then half way through the installation his screen suddenly turned blank, like as if the computer was off, when the computer is actually on.
And then he restarted his computer hoping to at least see those bios things everything you start your computer. But he see nothing, completely blank, he tried plugging the power cord out and in again, tried and still nothing.
He cant even go to safe mode, and he was wondering whats the problem. When he's updating his ATI driver he didn't uninstall the 9.7 though, so is that the source of this problem?
Anybody care to help? Thanks~
