Vga Output Becomes Full Red Or Other Color After 10 Minutes Working.

First have you tested the monitor on another device? If so then suspect the graphics card in the PC if it has an additional one. If you are using the onboard VGA output it will be the graphics chip on the board. It could be a driver fault but unlikely as you say it goes after 10 minutes. One way to test is to obtain an ice pack and put it in a waterproof bag. Start up the PC and when the fault occurs place the ice pack that is bagged onto the graphics chip on the board. If the fault disappears then you have solved it. You then need to decide whether to spend on replacing the chip. It will be soldered in so the cost can be expensive. You could try disabling the on-board VGA and fitting a video card and use that. However I cannot guarantee that will not be affected by the faulty onboard chip.Refer to the PCB guide to identify the graphics chip.

Hope that gives you some help in solving your problem.
