Okay...I am having lots of trouble trying to fix this problem. While on my computer, my monitor just randomnly goes blank, and the color of the light changes to an amber like color. I then press one of the buttons on the monitor, and it comes up with a message that says NO SIGNAL, and shows the three colors. I have to shut off my computer, wait a couple of minutes, then turn it back on, and it works fine. This happens maybe two or three times a day, and it's not at any specific time, I could be playing games, on this internet, or just listening to music. And sometimes, the computer will randomnly restart after the monitor says this. I am wondering if anybody has had this problem, and if anybody knows a solution. It is very annoying when I'm in the middle of something. - Could it be a motherboard problem??? I have an MSI KT-3 Ultra 2 motherboard. -What about a graphics card problem??
