Hello, today my friend bought a new video card and tried installing it by himself. He called me up and said his computer would not start up so I went over to his house and checked it out. I looked at the power supply and in the back of his PC there was a blinking green light. I found out that his new video card required a wattage of 300 and his power supply only went up to 215w. My question is could he have fried the video card or motherboard?
