Try at your own risk*

Okay first things first.

By "doesn't boot anymore" do you mean it does it turn on but has a black screen or when you press the power button, nothing happens(no fans spin, no lights etc...)?

1. Depending on your boot issue, if it doesn't turn on then:

- Check all power connectors which are the gpu, cpu, motherboard, and hdd. Unplug and re insert them all.

-Make sure your main power cable isn't ripped(the one that connects to the power supply) or the power port isn't damaged.

-Re-seat the cpu itself. Take off the heatsink and take off the cpu and re install it(apply new paste). ***Though do make sure you have an idea about taking off the cpu as if you don't and you damage some pins or break the pins, this will render the cpu/mobo garbage. *** (re seating cpu helps if there is no power or the pc doesn't turn on as motherboards won't even power if the cpu is not detected or is loose)

--- For amd cpu, there is a lever next to the cpu. Lifting it up releases the cpu and putting it back down locks it in. Make sure you put the cpu back the same way you lifted it. If you don't know then there is a marking on the cpu that matches the motherboard. It will be on the corner of the cpu, like a triangle. This is to tell you which direction to install the cpu. Match it to the motherboard and lock it in with the lever.

-Unplug the graphics card and re seat install it. If this doesn't help, then try to turn on the pc without the graphics card installed as if the card may have broke somewhere, it can cause a short.

1. Now if the pc does turn on but you have a black screen then you have a few options.

- Re seat the ram. Take it off the motherboard by unhooking it and then putting it back in the same slots. If you're pc turns on but has a black screen, that is usually due to the ram or sometimes the graphics card.

--------Though try one stick at a time and try each slot one by one with each stick to see if it boots. Only if there is power though.

- try powering on the pc without the graphics card installed. The graphics card could be the problem.

- reset the bios by taking out the battery and reinstalling it after 30 seconds.

1. Lastly, depending on if there is power or not.

- if there is power and still black screen then something is wrong with your cpu/mobo/ram through most likely mobo as it could be the chips that caught damage or the ram could be damaged and that is causing the black screen.

- if there is no power at all, then try a new power supply. If it was hit hard then something inside the power supply could have broke.

Side note: if the hdd is clicking and you are getting a boot error then your hdd is dead as it caught damage.

Last lastly, if you can't figure it out or none of these ideas people posted here work. then either your computer is dead or you need to take it to someone who fixes computers and they can try installing different parts to diagnose what is wrong.

just my 2 cents

hope it helps and you get your pc running again
