When i turn my dell pc on the fan starts going faster and faster, the power light turns turns orange instead of green and the screen says that there is no cable signal. Does anyone know how to fix this problem.
The fan all the way in the back just keeps going faster and faster. Also when i turn my PC on the lights n the back dont come on either.
I got a new motherboard a bit more than a year ago but the warranty has expired , there is also a orange light that comes on when the computer is plugged up, any suggestions
It sounds like the motherboard (or something in it) has developed a fault. You could try using a spare power supply just in case that's the problem, but it sounds like some repairs need to be carried out.
