dram light on cannot get screen on now

Hello. I had not updated my windows files in a while, so I started updating them,and when finished it asked me to restart the P.C. so I did, and now when clothe pc is turned on it wont show up on my monitor and theres a bunch of red lights inside. also was in msi "command center" messing with overclocking options and selected "game mode" or something before restarting p.c. and maybe this has more todo with it than the updates. I know nothing at all about computers, and now cant get a picture to show up on monitor when i turn on p.c.
