So, I plugged everything in correctly and the power is working fine to the video card and everything but there is no display. I get it to work after I unplug the card, unplug the pci, replug and then after a few times of repeating this AND tilting the case on an angle while powering on the display and keyboard will turn on... I can't tell if its the card because I have replaced the motherboard and power supply and neither helped. I got it to work a few times and it worked for about 2 weeks so I didn't return it and it passed the 30 day return. Not sure what I should do, I have the Radeon R9 270x video card, an ASUS P8B75-M/CSM LGA 1155 Intel B75 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard, and a Corsair 750w power supply.
