Today as i was installing my floppy drive in my computer, i plugged it in, closed the case, turned on the cpu and learned that i have no video. The weird thing is my video was working fine 3 mins beforehand, i turned my computer off, plugged in the floppy drive and then no video. At first i thought it was power supply related but i tested my power supply in another computer and it worked fine. I have also reconnected the graphics card and memory sticks and still no video. Any ideas to what the problem could be?
