3 and 4 for that model correspond to a memory issue. There is possibly a chip that has come loose or has gone bad and needs to be replaced.

Does the monitor go out completely, no power? Or just lose a signal? Check ALL cables, AC and Monitor cables. Could be a Graphics adapter issue or Monitor , try another monitor.Your computer has a few miles on it , right? You could buy a PCI Graphics card if the monitor is OK.

This is a major problem that crippled Dell. Moels Optiplex Gx260, Gx 280, and Dimensions of whose mdel number i don't remember have this problems. This signal shows that either a power supply or your motherboard is malfunctioning. If you have an insurance better use it now or else get some technical assistance.

Most likely from tripping over cables over


Hi George

I would simply recommend having the board replaced or upgraded as its not wise to have soldered connections flying around. The only problem is that the system being that old is not going to be an easy one to source a motherboard for.

Sorry i couldnt be any more help.

Hi, My name is Todd and I'm a customer advocate at Dell's corporate headquarters. My team helps customers via blogs, forums, and other tech sites online. You said the monitor is 2 years old. Do you have the original order number still? Depending on how you purchased the monitor it may have up to a 3 year manufacturer warranty and I may be able to replace it if it is within that warranty period. Please email me at Customer_Advocate@Dell.com if you can locate the order number and I'll be glad to see if its still under the manufacturer warranty. Include my first name (Todd) in the subject line of the email so it can quickly be routed through to me, and include the order or customer number if you have it. Thank you, Todd Customer Advocate Dell, Inc. http://direct2dell.com/one2one/archive/2006/11/19/3648.aspx
