I replaced an MSI Nvidia GeForce GTX 750 Ti video card with an MSI Nvidia GeForce GTX 1650 but now the MSI Z97 Mpower Max AC motherboard won't power on and its power and discharge buttons are flashing dimly/lightly. I tried removing the video card but same problem. Didn't touch anything else and made sure any static electricity was discharged before touching anything. Bad power supply? I have an Antec Truepower Trio TP3-550 (Watt). Any ideas? Thanks.
