hi, i tried to clean my pc. when i put in my graphics-card again, my moniter just said: no connection or something. I am not sure if my graphics card is broken or?? all of my fans are working, even the one on my graphics card, even though it is now a lot louder. I don't think it is my powersupply since everything else is working? well.. my usb ports doesn't work as well, but i guess they only turn on once windows is started?
