Just finished building my new computer. I have kind of an odd issue. I plugged in everything and my computer wont boot, after some troubleshooting I found out that if I unplug the 8pin connector on the graphics card with the 6pin still in, it will boot just fine. I have a msi z97-g45 mobo with a asus r9 290 4gb OC and a EVGA 1000w G2.. Power shouldn't be an issue, yes everything is plugged in correctly and I've tried all the pcie ports on the psu.. Let me know if anyone can help! Thanks!!
