Couple days ago, I installed a new headsink and fan for my processor! After i installed it, and i started my computer, my power supply blew. And now i just got a new power supply today, but my computer still wouldn't boot up. I turn it on, my video card wouldnt' boot up and neither is my dvd rom but everything else is fine. I've tried different video cards but it still wouldn't show up. can anyone help my problem, could it be the motherboard is fried b/c of the power supply incident? or something else, please help i am suffering
