I had my O.G running with no CD Drive in it. Wifi chip fried, Cooling fan running at 100% and it kept up with the trends. Compared it last night to friend's O.G and mine almost booted x2 faster.. Faster menus and gameplay etc. If it Powers on then off is your HDD cables… wiggle the connectors when powering on… I cleaned under my heatsink today for the first time since ‘14 or so says man. Date..removed CPU. Did everything like you should , And my power brick is on with an orange light and now i have no response from my console… no beep… no light… Brick just stays orange..did power cycle… I'm lost…. any idea, its all i have?? Cant afford a repair shop
