Details: CPU 9900k, Motherboard MSI MGP Z390, Gaming Edge AC GPU, ROG Strix GTX 1080, 32gb RAM (2x16gb), Corsair Vengeance.
Recent problem: PC freezes or sleeps but won’t power on. RAM stays lit, fans off, no light bar, startup fails. Only possible fix was a full 24-hour shutdown. Suspect faulty capacitors on motherboard. GPU debug light activates during boot. Planning to replace components soon, hoping it helps. No luck with PSU swap; GPU is hardwired and cooling system is watercooled. Looking for advice from others who’ve faced similar issues.
