Laptop won't start

[Helsabot]

Replaced thermal glue in my computer put it all back together computer booted making a loud noise from the fan until it shut itself down after about 30 minutes an now won't start at all.

Tried opening up the computer and making sure everything is right but my knowledge of this stuff is pretty limited.

I saw a few troubleshooting threads was hoping someone could help narrow down the problem since it did boot and now nothing.

Edit: I took my computer apart again and went through the whole process (I don't own a TV lol) and took a few photos.

Hi,

Just retrace your path on how you took everything apart and just double check if everything connected into their respected slot or connectors specially the fans, display cable to the motherboard. If everything is well seated and all connected properly you may need to consider on having a professional check it because most of the time this issue can be cause by static from your body if you didn't use an anti-static wrist strap.
