I bought a new Dell Inspiron 660 desktop about 3 months ago. Recently the CPU randomly stopped communication with the monitor and I had to hard reboot to fix the situation. I posted my problem on the World of Warcraft Tech Support Forums and one of their MVPs said "you have no display driver for starters" and posted this link for me: http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_win8-64.aspx.
So I downloaded the driver and it fixed the problem with my CPU not talking to my monitor. It has, however, caused another problem: my in-game Frames Per Second have dropped from 50-60 to 15-30. I will list as much computer infomation as I can below in hopes someone can help me out. I'm not a Tech guy by any means, so use kid gloves with me
Here's my computer info:
Operating System: Windows 8 64-bit (6.2, Build 9200) (9200.win8_gdr.130410-1505)
Processor: Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz (4 CPUs), ~3.3GHz
DirectX Version: DirectX 11
I hope this helps, but if I need to provide more information I will.
Thanks for your help,
