Back in May, my hard drive (Seagate Barracuda 7200.10 ST3250410AS 250GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive)crashed so I turned it in under its warranty. When I got the new one, I plugged it in only to find I had no video. I bought a new video card (GIGABYTE GV-N250-1GI GeForce GTS 250 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card)and when I plugged it in, it seemed to work fine. Two days later, I tried turning on the computer, got a quick flash of power to the fans but that was it so I bought a new PSU (APEVIA ATX-CW500WP4 500W ATX Power Supply
), thinking that was the problem.
I got the new PSU, plugged it in and still no power...until I unplugged the video card, then it started right up. I tried plugging in the video card and unplugging all other accessories but that didn't make a difference. Is it likely a MoBo (GIGABYTE GA-MA790FX-DS5 AM2+/AM2 AMD 790FX ATX Ultra Durable II AMD Motherboard)issue? It's quite perplexing that all these things are going wrong at the same time.
