I dealt with "Display driver stopped responding" error prompts and blue screens for about three months before finding the solution for my Gateway desktop FX6860 with Windows 7, i7 processor, 8 GB RAM and an AMD Radeon HD 6750 graphics card. I tried everything.
Finally after reading and rereading what seemed like every tech forum on the planet – and trying out every fix known to mankind -- I found a post that said it’s a RAM issue. The poster, who had a computer similar to mine, said he simply removed one of the
memory cards and that all of his problems disappeared.
So in a process that took less than 10 minutes, I unplugged my computer and opened the tower to carefully remove one of the four DDR3 memory cards – leaving me with 6GB of RAM instead of the 8GB that came from the factory. When I reconnected everything and
started up the PC, it worked perfectly. That was about two weeks ago. I haven’t experienced a blue screen or “Display driver” prompt since. I also haven’t detected any difference in my computer’s speed despite the absence of 2GB of RAM.
Apparently, my computer was unable to produce enough consistent power for 8GB of RAM without me messing with the clocking of my CPU (something I didn’t feel comfortable doing). But
by reducing the RAM, my computer is now able to produce the necessary power with consistency. In other words, my graphics card isn’t “timing out” or freezing any more. Hope this helps!
