So I’m running an MSI FM2 a55m e33 board, I had a dual core processor, just recently tried to upgrade to a 2.8 quad core, so I put in the processor, went to turn on my pc, and nothing happened. It powered on, screen stayed black. I had a gtx460, and I had a 450w psu, then I realized the gtx460, needs a 500w power supply and upgrading to a quad core sucking more power out, I possibly fried my videocard? Or motherboard? Bought a Used ASUS P5K motherboard, bought a 650w power supply, and an ati Radeon HD 6870, tried to set that up with the MSI board cause it’s a better board, powered on, and it powered on, didn’t display anything, and wouldn’t read the hard drive. Switched boards to the ASUS, and the psu clicks and shuts off right after I turn it on. ? At a loss and frustrated help?
