I am working with a custom built computer, the motherboard is an MSI ms-7030, processor AMD Atholon 64, 2.01 Ghz, with a NVIDIA GEForce fx 5500 graphics card. my problem is. Sometimes when I put a picture uploaded from a digital camera as my desktop background then start the computer back up there is a BLANK screen with an error message "no video input". the computer boots normally but this error message with the blank screen will keep comming up. If left for a few days the computer will start up without the error, I will restore to a point before the picture was used for the backgound an it will work normally again any thoughts on what the problem is would be appreciated.

ThanksNo Video Input generally is that the monitor is not getting a signal.. What do you use for screen resolution, and have to checked your video cable etc. Also how old is this DISPLAY and have you tested with a different display to see if the display is not syncing up to the video out. Also your graphics ADAPTER is an older GPU...how healthy is this card ( does it play games fine etc )...Also you stated that it boots fine but no signal... does the display show after a short while or something to GET to a good state? Sometimes weak power supplies will allow for the system to boot, but black screen ( no video ). So many things can be the cause...more info is NEEDED to go in a direction. As far as the image itself causing this...that is very unlikely. No Signal is NO Signal when it comes to NO Video Input. I think you are looking at a power supply that is tired or weak or inefficient for the power demand ( how many watts by the way ), a monitor issue, monitor cable issue, driver issue with the graphics adapter ( what version of nvidia Geforce are you using such as version 84.xx, or 192.xx etc, or the graphics adapter may be on its way out.

I'd go to NVidia's web site and make sure you have latest drivers for that card and not using Windows Default Drivers... see what happens and report back.
