Dear Friends, My dell desktop and flat panel have been very good for ~ 4 yrs.However, recently, when I switch the system on, the panel does not display the images.I have to switch it off using the main button a few times and then the no signal message flashes--> eventually, it starts up normally.Notably, there is no problem one it starts to display the images. I am worried it may affect the HD if I do this more often. Is it related to the flat panel life or some other component. Please advise Thanks Seth After Post Test, the Computer keyboard, Mouse and all other activities of the system will just be hung.

Could be a problem with the monitor or it could be a problem with the video card (or onboard video). Do you have another monitor you can try? How about a different PC to try the flat panel on?
