Hi
I have the same problem as other post on this topic, I have tried another monitor with the same results. It does not do it when res is set to 800 x 600 at either 16 or 32 bits. As soon as you go above this resolution it starts flashing at about 5 second rate. It seems to do it pretty well from cold, well about 3-4 minutes, could it be a heatsink problem on cpu or graphics chip or is this a known Dell Dimension 3000 problem. I am trying to lay my hands on a pci graphics card to eliminate that possibility.

Right, tried that, no problems showing up.
Bios is a bit limited, graphics adapter is set to auto, when I tried a pci card, nethr would work, how do I disable on-board card?

Hi, just checked out your bios setup. it dosen't appear that you disable intergrated video but you select primary video. Have you tried uninstalling the intel video driver & rebooting. You could download the intel driver from DELL & reinstall it

Ok, will try later, I did the driver bit last night, tried roll back as well, no difference, I will try and get the pci card to work again. I am wondering if it is a hardware fault in the graphics processor as disabling some of the direct x and 3d options appeared to slow the flashing down to perhaps once a minute.
Thanks.

Success!
It was monitor, 1st monitor tried was a HANNS-G, flashing still, tried another one, same make, still flashing, put a 3rd one on, good old tube type no flashing.
The people who own the monitors and computer are heavy smokers, so I stripped them and inside they were covered in nicotine. Cleaned with pcb cleaner and sprayed with conformal coating, all now working ok!
Big sign on door now..NO SMOKING !
Thanks for previous advice.
