Hello,I just tried installing a new graphics card and more RAM (another 4GB for a total of 8). After installing both I tried booting up my computer to find no signal being received by my monitor. Neither my keyboard (backlights) or wireless mouse reciever turn on either, both of which are hooked into the the USB ports in the back. Thinking it was the new card I put my old one in as well as tried connecting to the motherboards DVI. Neither one worked. All of my fans work and the LEDs on the mobo light up. So I don't belive its the PSU. My hard drive will start spinning on start up but will stop seconds later. I have tried resetting the BIOS by removing the watch battery on the motherboard as well. I'm of the mind that either the CPU or the motherboard were fried somehow, but can't be sure. Any suggestions?
