I have had this problem ever since I got my computer, and I really do not know what causes it. Whenever I use a graphics-extensive program, such as a game or a program like After Effects, or even watching movies on the internet, my screen flickers. It is not because of my refresh rate on my monitor, because I have tried different settings, and I have also tried different monitors, which rules that out.
When I first got my computer about 16 months ago, I was about to return it, because for a week I couldn't figure it out. What finally worked was downloading older driver for my video card, which somehow fixed the problem for games, but if I tried to watch a dvd, then the flickering would return. Also, I noticed the screen flickering was much worse when I first got my computer than it is now; then I had XP 32 bit, now I have Windows 7 64 bit (not sure if that's important or not).
I just installed Windows 7 a few days ago, and tried the same drivers that helped the problem when I was running XP, but that did not work, even though I downloaded the 64 bit version of it.
As of now, I have the latest driver installed for my graphics card, which is a Ati Radeon HD 4870 PCI-E 16x 1GB DDR5.
The screen flickers when I play any games, when I use Adobe programs, like Photoshop and After Effects, and when I watch videos or dvds.
If anyone could help me with this problem, I would be truly grateful. If there is any information you need from me, please ask and I will respond asap.
