I have aHP Pavilion 23-b090 All-in-One Desktop and I made the horrible mistake of updating to Windows 8.1 and now my Video card will not work. I can't watch videos that I've made or use my dual monitors.Iwent into "Device Manager" and I found that I have a "Code 43"... I have a AMD Radeon HD 7540D Video card. I'm also operating on a 64 bit system.
I've tried to update drivers but to no use. I still have that yellow triangle on my video card.
I contacted Microsoft and they were just about useless... I have a TON of digital art programs on my computer so I'm not trying to do a system recovery because I'll have to re-install all my programs.
