Just built this thing (first time in like 20 years so...)
ryzen 5 2600 on a b450 motherboard (so no onboard graphics), RX 580 8gb pulse graphics, corsair 550w psu (details below);
Had all running yesterday. Spent the evening installing, downloading and updating, restarting.. computer slept last night, woke it and then another restart (something crashed when I tried to run a MATLAB installer!?) - then a blank display. POST fails on VGA (mb VGA debug LED is on).
The monitor is getting a blank signal (it comes on with computer power on, but blank screen).
(One hint maybe, it took me a while to figure out that I couldn't get any display with hdmi, after I first assembled it, it posted but without display and waited for input.. had to scrounge up a dvi monitor and cable - thought I'd figure out hdmi later - is it always the case that hdmi out has to be set up with GPU drivers installed? or should they have worked from the outset)
tldr; post fails on vga, no display - computer worked initially
what could it be? what should I try?
thanks
