Dear all, I have a strange problem with my display. Symptoms are as follows, flickering at a high rate Undulating pictures. My system is Evesham axis rk 1900 xp radeon 8500le graphics card samsung syncmaster957df.
What makes this strange is that it only seems to happen at night and is not dependent whether or not the computer has been on during the day. I have checked drivers and settings in display also I have run virus and spyware software Could anyone help please
Not that I can think of spartan. Unless there is a strong electrical field near your monitor, but this would affect the display in the daytime as well as night.
Can you pinpoint the timing of this? Does it happen when you turn on your PC at or after a certain/exact time of day? If it's only at night, is it because some other appliance has come on that is not so in the day?
Depending on where in your home the PC is situated and plugged into the mains power supply, it may be on the same "Ring circuit" as something that is causing the interference.
To test this, use an extension power lead to take the power supply from a different circuit in the house. Try this and please post back with the results, and any more information you can think of.
PS. Is there any reason that you may suspect the power supply?
