Hello, this is my first post here. I have a Gateway Desktop that was working fine until I changed a registry entry for System Pages Value Data. I changed this setting following instructions to solve a delay write error that one of my external HDDs was having. I did not write down the original value. I changed the setting to -ffffffff- eight "f"s per instruction.
Now my computer hangs at the Gateway F2, F10 screen and will not accept keyboard input. My immediate but temporary solution is to pull the CMOS battery and re-boot. Then the computer starts fine. I just have to rest the system time.
I will really appreciate any help that will solve my situation permanently
