Question about Dell (002TR) Motherboard
Could you tell me what OS version you are running? I have encountered this issue before and can only provide you with the problem that I came across personally. If you are running Windows 7 you will get what looks like a really annoying refresh flash. I swapped back to Vista and the issue disappeared. Another piece of software that I found caused the issue was Acronis true image 2010 - when loaded the flashing started - I removed it and it stopped.
So it could be a software application - if you have access to another hard disk it might be worth building a clean version of your operating system and seeing if you have the same issue.
