My friend has Windows 7 installed on his PC but he can't start it normally because the monitor goes black and displays the error message, "OVER-FREQUENCY" with the V=60.*Hz, H=70.*Hz (something like that, not sure of the numbers) on the screen.
I did the following things hoping that they will fix the problem:
1) I restored the monitor's factory settings by using the recall function.
2) Started the computer on Safe Mode and picked the lowest possible resolution and refresh rate--640X480, 60Hz, 16-bit color.
But to no avail.
I tested his CPU on another monitor (which is my monitor, not same brand) and it did fine. Windows 7 started normally.
What could be causing this error/problem? I'm thinking it's the monitor since his CPU worked on my monitor but not on his.
Your help will be much appreciated. Thank you!
