PS5 Random shut downs

Hello peeps, long time viewer first time chatter. I have this problem with my first gen PS5 (launch console), its been working great up until 2 weeks ago, it mainly happens on motorfest game and i cannot turn it back on unless I unplug from wall and hit power button on unit. Also i use to use my PS5 vertically and then switched back to horizontally. I did a air cleaning 4 days ago and the liquid metal was all balled up to 1 end of the of the chip. Ill tried to spread it out as much as i can but there is a dark spot. I order some last night and should be here soon, but it realy the chip or bad power supply?

thanks
