Bad Graphics Card? Replacement?
Over the last 2 days my computer has been very, very sad 😟 Bad graphics glitches. Freezes. Bad startups, etc.
All my RAM seems to be okay, and my startup disk does, too.
So I was wondering if my graphics card had gone belly up?
I have a GForce 8800.
My buddy at work had a fairly new ATI Radeon HD 2600 HD, and he gave it to me today to test.
I came home, and swapped them out. But I get BLACK on my monitor. Nothing. Nada.
The Nvidia still works (although it gives me the glitches and the now-frequent panics).
Do I need a DRIVER for this ATI?
If I can't boot up 100% how can i hope to install it?
