After a power outage i turn on my computer and it was all fine, so i played a few games and noticed that my fps was higher (average 70 fps instead of 55). So after a bit more gaming then my monitor went black and said no signal. I restarted my computer and nothing happened so i tryed to go into bios and it worked i looked around a bit and saw that everything was fine. Windows does not start at all basically. Can any please tell me what is happening and how i can fix it.
Its a brand new computer at 3 days old.

Rx 5700 xt sapphire pulse
seagate 2tb sshd
