old system:
CPU / I5-6600k
MOBO / MSI Z170 Krait Gaming 3X
Memory / DDR4-3200
GPU / RTX 3070
PSU / Corsair RM650X
new system
CPU / I7-9700k
MOBO / Gigabyte Auros Elite Z390
Memory / DDR4-3200
GPU / RTX 3070
PSU / Corsair RM750X
About a week and a half ago, I got my I7 and my new motherboard to upgrade my computer. After putting it together with the old power supply (650 watts), I turned on the power, but the mobo lights flashed for half a second then shut off. Turning it off/on right afterwards did nothing, but if I waited around 30 seconds to turn it back on, then I would get another flash. I figured it was a dead cpu, so I put my old computer back together and well, the old computer doesn't turn on either. I have rebuilt both of my systems multiple times, as well as resetting my CMOS on both motherboards multiple times. I have done the paperclip test on both of my power supplies and they both work, I'm just extremely confused as to what might have happened. I have also been grounded at all times when working on it. Any help or suggestions would be helpful, school just started back up for me and I kind of need this thing for my computer science class. I'm working on a <Mod Edit> laptop right now but it is definitely not good. Thank you for any replies.
