Question PC got hit & won't display so need help troubleshooting ?

[caroccp]

A few months back, someone dropped something on my pc (desktop) and since then it will not display. The pc was turned off when it was hit. I've just recently tried to figure out what's wrong with it and I've taken it apart & put it back together, but it still does not display.

Pc boots, fans spin (except GPU fans). No beep codes. Visually nothing looks obviously damaged or chipped & everything slots correctly.

Things I have tried:
-GPU on the other slot available.
- Switching through all the RAM sticks to see if it'd work with only one of them.
-Checked that the HDMI cable works & the screen works on another pc.
- Inspected visually for cracks

I'm at a bit of a loss, if anyone knows what else I could try I'd really appreciate it!!

PC Specs:
AMD FX-8320 3.5 GHz 8-Core
MSI 970A SLI Krait Edition ATX AM3+ Motherboard
MSI GAMING Radeon R9 380 2 GB Video Card

As I understand your post the CPU does not have integrated graphics:

Reference:

This motherboard?

Use a bright flashlight and take a careful look around the I/O panel and the PCI slots. Inside and out.

Something may have gotten a bit bent or moved out of place and is causing a short.

Failing that, what PSU is installed? Make, model, wattage, age, condition?

Perhaps the PSU took the hit and is unable to properly provide all of the necessary voltages and wattages.

If possible swap in another known working PSU.

Remember if modular use only the cables that come with the modular PSU.

Yes, I do not have any integrated graphics, and yes it is that motherboard (although the EU version, I think there might be a few minor differences)

After checking the I/O and pci slots, I can see there is no damage. If there was a short, would certain components still run? Because the cooler fan runs.

The PSU fan does run. When the pc got hit, the closest component to it would have been the psu.

Make: FX800B
Manufacturer: Keep Out
Wattage: 800W
Age: 5 years approx
Condition: computer has been used intensively for 2 years, then not frequently for the following 3.
Just to add, I do live in a hot place year round.

This is the site for the PSU

I have another computer that runs, can I simply unmount that PSU and use it on this? Do I need to check for any kind of compatibility?

Thank you again

A 5 year old PSU is certainly a potential culprit. The hit may have jarred some internal PSU component (non-repairable by the way) and that led to some failure.

PSU's provide three different voltages (3, 5, and 12) to various system components. A problem with any voltage can cause system failure while other components appear to be working.

I am not familiar with the linked PSU. It is non-modular so you should be able to swap in an other non-modular PSU of the same or higher wattage. Just check the installation intructions and ensure that all connections can be made.

If you swap in a modular PSU then use only the cables that come with/came with that PSU.

Do some planning beforehand and, as should always be being done, back up all important data to another location away from the problem PC. Verify that the backups are recoverable and readable.
